Gmail on your own domain, so mail arrives at your name at your company’s address rather than at a gmail.com one, means a Google Workspace subscription. Two things have to happen together: you pay for the subscription, and you prove you own the domain. Buying the subscription with a gmail.com address does not give you the custom address on its own. Google also documents a second arrangement, and its sending half has a January 2027 end date on it. Both are below.
The setup itself is not hard. It is unforgiving about dates. Three separate organisations run a clock over this setup, and they start at different moments. Google’s starts when you sign up: it asks for verification within nine days, and it deletes an unverified account at 21 days unless billing is set up and the subscription is active. Answer any contact-verification email from your domain registrar, the company that sells and records the domain name. For a domain bought inside Google’s signup, Google documents a 15-day clock on that, starting at purchase, and puts the requirement on ICANN rather than on itself. If you want a .com.sg, Singapore’s domain registry starts a 21-day clock on the day the name is registered.
Before you start, here is the whole job.
- Buy a domain, or use one you already own. In Singapore this is the step that forks, because
.com.sghas an eligibility test before it has a price. - Sign up for Google Workspace and prove you own the domain. This changes nothing about your current email.
- Create everyone’s accounts. Do this before the next step, not after.
- Point your domain’s mail at Google. This is the step that actually moves your email, and a mistake here is visible to everyone who writes to you.
Prices in this guide were checked on 5 September 2026, in Google’s own admin help.
Can I use Gmail with my own domain for free?
No. Getting an address at your own company name from Google means paying for Google Workspace. There is a workaround for anyone whose domain mail is already hosted somewhere else, and Google has put an end date on half of it. Both are set out below, because the two get confused with each other.
A personal Gmail account gives you an address ending in gmail.com. Getting an address at your own company name is a separate step, and Google puts it behind domain verification on a paid subscription.
Paying for Google Workspace and owning a domain are two separate things, and you can do the first without getting what you wanted. Google’s admin help on Gmail-based Google Workspace accounts says that “If you run a one-person business using your personal Gmail address (ends in @gmail.com), you can sign up for a Google Workspace Business edition using that address”. So the payment goes through and the subscription is real. But the same page adds that “To unlock the full feature set for any edition, you need to verify your domain.” The follow-on page is blunter still: “When you verify your domain, you get a custom domain email address.”
Put plainly: the subscription buys you the service, and verifying a domain is what turns it into an address at your own company name. One without the other leaves you paying for Workspace while still sending from gmail.com.
The free route has a date on it now
There is a workaround people use instead of paying, and it still works, for now. You point your domain’s incoming mail at a free Gmail account, and you use Gmail’s Send as setting so replies go out showing your own address. Two halves: receiving, and sending.
Google has put an end date on the sending half. Its help page on sending emails from a different address or alias carries a notice. Starting January 2027, it says, Gmail will no longer support the Send as feature “for third-party email addresses, such as @yahoo.com or @outlook.com”. The notice then draws the line: “This change does not affect Google Workspace aliases or other Gmail addresses you own.”
Read the rule and the examples separately, because they are not the same width. The rule Google states is about addresses it does not host. On its detail page for the change, Send as keeps working “for any Google-hosted identities, including other Gmail addresses or aliases associated with your Google Workspace account”, and the same page adds that “The discontinuation will not impact these addresses, which only applies to third-party, non-Google email accounts.”
The examples are narrower than the rule. Every address Google prints beside the removal is a consumer mailbox: the notice names @yahoo.com and @outlook.com, the detail page names @hotmail.com and @yahoo.com. One non-consumer word does sit beside the removal, though, and it is a category rather than an address. The detail page describes the feature it is withdrawing as one that lets you send “from a different address you own, such as work aliases or non-Gmail accounts”. So a company domain is named in kind, even though no company domain appears among the examples.
The same send-as page points the other way, though, and this is the part to weigh. Where it lists the addresses you can add in the first place, it includes “Your work, school, or business domain or alias, like @yourschool.edu or [email protected]”. So a company domain is plainly inside what the feature is for, while sitting outside every example of what is being taken away.
Which leaves this: if your own domain’s mail is hosted somewhere other than Google, Google’s stated rule reaches it and Google’s published examples do not. That is an uncomfortable place to plan from, and it is the honest description of what these two pages say today. If you are running your domain that way, treat January 2027 as the date to have moved by rather than the date to find out on.
The receiving half survives if it is done by forwarding. Google’s detail page asks whether you can still receive email forwarded from a third-party account, answers yes, and explains how: “You can configure your third-party provider to auto-forward messages to your Gmail address.” It adds that forwarding is independent of the Send as feature.
Pulling the mail in instead does not survive on the web. The same page lists what is going under two headings, and the second is “Gmailify & POP on the web”. Gmailify is the feature that “allows you to get Gmail features applied to your third-party email account”. Under the same heading: “Check mail from other accounts: Gmail will no longer fetch emails from third-party accounts into your Gmail account with POP.” The timeline removes both in January 2027 alongside Send as. The phones are the exception: “Access through the Gmail mobile app for Android, iPhone, and iPad will not change.”
The change is already under way rather than parked in 2027. Google’s published timeline puts the notice period in the third quarter of 2026 and a transition period across the third and fourth quarters, during which Send as for third-party accounts, Gmailify and POP “continue to work, but Gmail may restrict new configurations.” Full removal is January 2027. Setting this route up fresh today may simply not take.
Google’s own advice to anyone whose business relies on the feature lists three options. The first is a desktop mail program that supports IMAP and SMTP, which are the standards mail programs use to fetch and send mail on your behalf. The second is your provider’s own website. The third is the one this article is about: “Use Google Workspace for a custom domain.”
Three deadlines, three different organisations
This is the part that costs people their weekend. Three bodies keep these clocks, they do not talk to each other, and each one publishes its rule somewhere different.
| Who is counting | How long | What you have to do | What happens if you miss it |
|---|---|---|---|
| 9 days to verify; the account goes at 21 days from signup | Prove you own the domain | The account is deleted, unless billing is set up and the subscription is active | |
| Your registrar, via ICANN | 15 days from purchase | Click the link in the contact-verification email | The domain is suspended, and Google says Gmail cannot send or receive for a suspended domain |
| SGNIC, for any new .sg name | 21 calendar days from registration | Verify identity with Singpass or Corppass | The domain is suspended, and its website and email stop working. SGNIC says you can ask for a 7-day extension, once |
Google’s clock has two numbers on it, and they mean different things. Its page on verifying your domain gives the instruction as “You must verify your domain within the first 9 days of your free trial period, or when starting a paid contract”, and warns that “A Google Workspace account with an unverified primary domain is subject to automatic cancellation.” Then, marked Important, it gives the consequence: “If you don’t verify your domain, your account will be automatically deleted within 21 days of signup. However, if you have set up billing and have an active subscription, the account won’t be deleted.” Nine days is the deadline Google asks you to work to. Twenty-one is when the account goes, and setting up billing is what stops it.
Google documents the registrar’s clock for a domain bought inside its signup, and it puts the requirement on ICANN rather than on itself. Its page on purchasing a domain at signup says twice that the check is “required by ICANN (the governing body for domain registration)”, and that the message goes to the address you used to sign up. Then: “If you don’t confirm your contact information within 15 days of purchase, the registrar is required to suspend your domain. Gmail can’t send and receive email for a suspended domain.”
That page says nothing about a domain bought anywhere else, so do not read this as a clock that stops at Google’s door. Answer any contact-verification email your registrar sends, whoever you bought from. That email is easy to miss, because it arrives at the address you are in the middle of replacing.
The Singapore clock is covered in the next section, because it comes attached to a set of rules that decide whether you can register the name at all.
Buying a .com.sg is a different job from buying a .com
For most extensions, buying a domain is a checkout. For a .com.sg it is a two-stage application with an eligibility test at the front and a deadline at the back.
You have to be eligible before you can be a customer. SGNIC is the registry that runs Singapore’s .sg names. Its eGuide on choosing a .SG extension sets the test: “Applicants registering for a .com.sg will need to be either registered, or in the midst of registering, with the Accounting & Corporate Regulatory Authority (ACRA), IE Singapore or any professional body.” ACRA is the government body that registers businesses in Singapore. The allowance for a company “in the midst of registering” matters for anyone incorporating now, because it means the domain does not have to wait for the company.
For a company based outside Singapore the same page adds a condition: “A foreign company which is not so registered may only apply for a .com.sg domain name if it appoints a local agent as the Administrative Contact. The administrative contact must furnish a valid Singapore postal address for SGNIC’s records”. The administrative contact is the person or organisation named on the domain’s record with SGNIC, and the one SGNIC expects to do the identity check below.
Then the identity check, and this is the clock. SGNIC’s VerifiedID@SG FAQ states that “All new .sg domain names need to undergo verification using Singpass/Corppass”. Singpass and Corppass are Singapore’s national login services, personal and business. The administrative contact does the verification, and the FAQ says the process “should take less than 5 minutes”.
The consequence of not doing it is stated plainly: “If a newly registered domain name is not verified by the administrative contact within 21 calendar days of registration, the domain name will be suspended (i.e. its website and emails will cease to function).” The FAQ also gives the general rule as a “grace period of 21 calendar days from the date of registration” to perform the verification, after which “SGNIC will suspend the domain name.”
SGNIC does publish one way out. The same FAQ says anyone can “seek a temporary extension of the verification due date by 7 days”, and that “The due date can only be extended once.” You still have to ask for it, and you still have to do the check.
So a Singapore business that wanted an address at its own name can end up with a dead one three weeks later, because a five-minute login never happened.
What Google’s own domain-buying route does and does not cover
You can buy a domain inside Google’s signup flow, which removes two of the hardest steps in this whole guide. Google is not the seller, though. Its page on purchasing a domain names the partner: “If you want to use Google services with your organization but you don’t have a domain name, you can purchase with our partner, Squarespace.” The domain is then already verified, because Google’s verification page states that “If you purchased a domain when you signed up for Google Workspace, or if your account is managed by a reseller, your domain has already been verified. No further steps are needed.” Mail routing is handled too, because the MX records, the lines in your domain’s settings that tell other mail servers where to deliver, are set for you: “Your domain’s MX records automatically point to Google’s mail servers”.
That is a genuinely easier path, and for a business that is happy with a .com it is the one we would point most first-timers at.
It does not reach a .com.sg. Squarespace publishes a list of the top-level domains it sells, stamped “Last updated July 30, 2026”. Its country-code section enumerates nineteen entries, covering Australia, Canada, the Cocos (Keeling) Islands, Colombia, the European Union, France, Germany, India, Italy, Japan, Mexico, Montenegro, the Netherlands, New Zealand, Palau, Poland, South Korea, the United Kingdom and the United States. Singapore is not among them, and no .sg extension appears anywhere on that page. The page states its own general position as “We don’t offer most country code TLDs, such as .ru, for registration or transfer”, and tells readers what to do instead: “If you’re interested in a ccTLD that isn’t included in the list, you can register one with a third-party provider and connect it to your Squarespace site instead.”
That is a statement about one company’s published catalogue on one date, not about what Google will or will not allow. The practical effect for a Singapore reader is the same either way. If you want a .com.sg, buy it from a Singapore registrar first, then bring it to Google. The domain decision comes before the Google decision, and which extension you choose changes where you have to buy it.
Pick the name as though you are stuck with it
Google puts this in one line on the purchase page, and in our view it is the line on it that matters most: “Choose your name carefully”. Your primary domain is the one every address in the company is built on, and Google’s own warning is that “It’s not easy to change your primary domain name later.” Changing it means changing everybody’s address.
The same page also settles a myth worth settling: “Purchasing a domain from Squarespace makes it easier to get started with some Google services, but it has no impact on your position in Google search results.”
And on the money, because a domain behaves differently from a subscription: “You initially purchase your domain for a year”, and “Unlike your Google service charges, which are monthly, you renew your domain annually. You’ll be charged a higher amount on your invoice once per year when your domain registration renews.” Google also states that “All sales are final”. Its free-trial page adds that you can move the domain elsewhere “after 60 days from when you purchased it (according to ICANN regulations)”.
The setup, in the order that does not bounce your mail
Four steps. The order matters more than any individual step, because one of these moves your mail and the other three do not.
Step one: prove you own the domain, and stop worrying about this one. Verification means putting a short code from Google into your domain’s DNS settings. DNS is the internet’s address book: a set of records at your registrar that tell the rest of the world where your website and your mail live. The reassuring part is stated by Google directly: “Verifying your domain doesn’t affect your email or website.” Nothing moves at this step. Google says that “Adding your Google Workspace verification record takes about 10 minutes”, and that once the record is live, “it can take up to one hour for us to confirm you added the record, but it usually happens quickly”.
Step two: create everybody’s account, before you touch mail routing. MX records are the lines in your domain’s DNS that tell other mail servers which machine takes your mail, and changing them is step three. This is the sequencing fix, and it comes straight from Google’s page on avoiding issues when changing MX records: “Before you change your MX records, create your new Google Workspace user accounts in the Google Admin console.” Mail that arrives for an address that does not exist yet has nowhere to go. Do this first and there is nothing to bounce.
Step three: point your domain’s mail at Google. This is the step that moves your email, and a mistake here is visible to everyone who writes to you.
The value is one line, which is a change worth knowing about if you last did this a few years ago. Google’s page on setting up MX records states it: “The Google Workspace MX record value is smtp.google.com.” Type MX, name left blank or set to @, priority 1, and any other MX records removed, because Google warns that “Your email might not work correctly if you keep old or incorrect MX records.”
If your mail already works on an older setup, leave it alone. Google’s own note: “If you started using Google Workspace before 2023, your domain might have different MX record values that start with “aspmx”. If your email is working, no changes are required. Any account can use the new single MX record value, but the legacy MX record values are still supported.”
Step four: switch Gmail on in the Admin console, under Account, then Domains, then Manage domains. Google’s own page numbers this as the step after the records.
How long the switchover takes, and what to tell people
Google’s two pages give two different figures here, so both are worth having. The MX setup page says “It can take up to 72 hours for the new MX records to be recognized.” The page on avoiding issues says “It can take up to 48 hours for your Google MX records to propagate. Until the new records are active, emails are directed to your previous email provider.” Plan for the longer one and be pleasantly surprised.
Nothing is lost in the gap, but some things arrive in the old place. Google’s advice is to schedule the change for “when your email volume is low, such as in the evening or on the weekend”, to tell key contacts the date and time in advance, and to “Assure contacts that no messages will be lost, but some might need to be resent.”
One small trap on the way in. If you use one-time passwords, Google warns that “they will stop working after your Google Workspace email setup is complete”, and that “You must create a new password for this account before you set up MX records and activate Gmail”. Do that before the switch, not after, or you are locked out at exactly the wrong moment.
Landing in the inbox is a separate job from getting the mail delivered, and it is decided by three more DNS records. We have written that up in why business email lands in spam, which covers SPF, DKIM and DMARC. If you have years of old mail sitting with your current host, moving it across is its own project, and our guide to moving IMAP mailboxes to Google Workspace is the one for that.
If your business already runs on a personal Gmail address
This is common in a one-person business, and converting is a real option rather than a fresh start. Google documents what happens in some detail, including one consequence worth reading before you set up a second administrator.
Your existing mail and files come with you. From Google’s page on verifying a domain on a Gmail-based account: “All of your emails from your Gmail address, as well as any Google Drive files and other data from your Gmail account, are retained in your new domain-verified account under your custom email address. Your custom email address becomes your primary address for sending and receiving emails. You continue to receive emails sent to your Gmail address, and you can choose to send emails from your Gmail address.”
It is reversible. The same page: “When you cancel your Workspace subscription, all of your messages and data are transferred to the Gmail address you used when you signed up.”
You lose some consumer Google services, and they are named. “Domain-verified accounts don’t support some services that work with personal Gmail. For example, if you verify your domain, you can no longer use Google Family, Google Fit, or Google Nest.” If your household runs on any of those from the same account, that is a real cost and it belongs in the decision.
And the one to think about before you make a business partner a super admin. A super admin is an account with full control over every part of your Google service. Google’s page explains that another super admin can remove you and may let you keep your data, then states the other outcome: “a super admin can also choose to delete all your data when removing you from the account. In this case, all the data from your domain-verified account, including any Gmail account data that was carried over, is permanently deleted.”
Read that with a two-founder business in mind. The mail and files you carried in from years of a personal account sit inside the thing the other admin can delete. Google’s own advice is to “use care when making another user a super admin”, and ours is the same: two admins is right for continuity, and the day you set the second one up is the day to talk about it.
What it costs
Business Starter is the lowest-priced edition on the page Google uses to compare its two payment plans, and that page prints two Singapore dollar rates for it. On Google’s admin-help page comparing the flexible and annual payment plans, the Singapore dollar row for Business Starter reads $11.2 on the Flexible Plan, whose contract is listed as None, and $9.4 on the Annual Plan, whose contract is listed as 1 year. Both are per user per month, and both were checked on 5 September 2026. That page carries no statement about GST against its Singapore figures either way, so treat them as figures to confirm on your own invoice.
Which of the two plans to take is a genuine decision rather than a formality, and we have set out the trade in the flexible plan against the annual commitment. Editions and pricing are on our Google Workspace pricing in Singapore page.
The trial is 14 days and has more shape to it than the number suggests. Google’s page on the free trial says “Up to 10 users can explore the features of Google Workspace”, that “Before you can use Google Workspace, you need to complete the payment setup”, and that “When you add an 11th user, you are prompted to end your trial and your paid subscription begins for all users.” It also gives the ending you want to avoid: “If your trial period ends and you haven’t set up billing, your account will be suspended.”
Which loops back to the first clock. Setting up billing during the trial is what protects the account from the 21-day deletion, so it is not a step to leave until the end.
One more address worth setting up early: the shared info@ or sales@ that more than one person needs to answer. That is a different setup from a personal mailbox, and the ways to run a shared inbox in Gmail covers it.
Common questions
Do I need Google Workspace to use Gmail with my own domain? Yes. Google’s help pages put a custom domain address behind two things together: a paid Google Workspace subscription, and a domain you have verified. A subscription bought with a gmail.com address does not give you the custom address until that verification is done. The second arrangement Google also documents is a different thing, and its sending half ends in January 2027.
Will my current email stop working while I set this up? Not until you change the MX records. Google states that verifying your domain “doesn’t affect your email or website”, so nothing before that step touches the mail you have now. The dates still bind, though. Verify inside Google’s nine days, set up billing before the 21-day deletion, and clear the registrar and SGNIC verification emails as they arrive.
How long does the switch take? Google’s two pages give up to 48 hours on one and up to 72 on the other. Mail sent during the gap goes to your old provider rather than disappearing.
Can I buy a .com.sg through Google? Not through the domain-buying step inside Google’s signup, which runs through Squarespace. Squarespace’s published list of country-code extensions names nineteen entries and no Singapore one, and its own page says an unlisted country code has to be registered elsewhere. Buy the .com.sg from a Singapore registrar and connect it to Google afterwards.
What is the MX record for Google Workspace? Google publishes it as a single value, smtp.google.com, at priority 1. Older accounts set up before 2023 may still have several records starting with aspmx, and Google says those keep working and need no change if mail is arriving.
What happens to my old Gmail if I convert it? Google says your mail, Drive files and other data are retained under the new custom address, that the custom address becomes your primary one, and that you continue to receive mail sent to the old gmail.com address.
Is there any free way to do this? Receiving mail at your own domain still works if something else is already hosting that domain’s mail and forwarding it into a free Gmail account. Google answers that question directly with a yes, and adds that forwarding is independent of the Send as feature. Sending from your own address that way relies on the “Send as” feature Google is removing for third-party addresses in January 2027, with new configurations already at risk of restriction during the transition.
Where to start
Settle the domain before you open a Google page. Decide the name, decide the extension, and if the answer is .com.sg check the ACRA position first, because that decides where you can buy it and starts a clock the moment you do.
Then sign up, set up billing during the trial rather than at the end of it, verify the domain, and put the dates in your calendar: Google’s, your registrar’s, and, if the name is a .sg, SGNIC’s. Create the accounts. Change the MX records last, on a quiet evening, having told the people who email you most.
If you would rather not do the DNS part yourself, that is ordinary work for us. Our Google Workspace services page explains how we work. Tell us the domain you want and how many people need an address, and we will tell you what it costs and what has to happen in what order.
