Using Gmail with your business email: what still works after January 2027

Updated

Many small business owners keep their business mail in Gmail because it is what they already use. Google is changing what Gmail will do with outside addresses, and the change lands in January 2027. Here is what stops, what keeps working, and the setups that will last. We are a provider of city domain mailboxes, so we have an interest here, but the facts below come from Google's own help pages.

What Google is changing

The banner on Google's send emails from a different address page says: "Starting January 2027, Gmail will no longer support the "Send as" feature for third-party email addresses, such as @yahoo.com or @outlook.com. This change does not affect Google Workspace aliases or other Gmail addresses you own."

The detail page, Learn about changes to third-party email account support in Gmail, says: "You will no longer be able to send mail from third-party email accounts in Gmail on the web or in the Gmail mobile apps." It also says Gmail-to-Gmail aliases and Google Workspace "Send as" are not affected.

Three things are ending in January 2027, according to Google's timeline:

  • "Send as" for third-party accounts, such as sending as you@yourbusiness from a free Gmail account.
  • Gmailify.
  • POP fetch, the "Check mail from other accounts" feature. Google's page on Gmailify and POP changes says that after the first quarter of 2026 the feature no longer supports new users, and existing users can keep using it until January 2027.

Google also describes a transition period in the second half of 2026 where these features keep working but Gmail "may restrict new configurations." So if you are setting this up now, it may not work, and if it does, it will stop.

What is not changing

The same Google page says: "Access through the Gmail mobile app for Android, iPhone, and iPad will not change. You can continue to add and use non-Google accounts in the Gmail mobile app." Google's recommended options are to use the provider's own site or app, to configure a desktop client to connect to the third-party account through IMAP and SMTP, or to use the Gmail app for Android, iPhone or iPad.

So the line is this. Gmail on the web stops being a place to read or send as an outside address. A mail app, including the Gmail mobile app, talking to the outside mailbox directly is not affected.

Setups that will keep working

A. Add the business mailbox to the Gmail mobile app as its own IMAP account

Google's page on adding another email account in the Gmail app says you can add another account, but you cannot add accounts like Exchange and POP. Google's Gmailify page notes the app uses a standard IMAP connection. The business mailbox shows up as its own account in the app, with its own inbox, and mail you send from it goes through your provider's outgoing server, not through your Gmail address.

Menu names change between app versions, so treat these as a general outline:

  1. Open the Gmail app and tap your profile picture.
  2. Choose the option to add another account.
  3. Pick the option for another email provider or IMAP, not Google, Exchange or POP.
  4. Enter your full business email address.
  5. When asked for incoming and outgoing server settings, enter the ones your mail provider gave you, with the full address as the username and your mailbox password.
  6. Send yourself a test message, then reply to it from the new account to confirm sending works.

Use the settings from your provider, not a guess. Ours are shown on your account page in the Mail app settings card. They use IMAP and SMTP with SSL.

B. A desktop mail app

Outlook, Apple Mail and Thunderbird all connect over IMAP and SMTP, and Google's own list of options includes configuring a desktop client this way. The setup uses the same provider settings as above. This is a good choice if you work at a computer most of the day.

C. Webmail

Every mailbox has a web inbox that needs no setup at all. It is plain and reliable, and it makes a good fallback if an app misbehaves.

What not to build on

Gmail on the web with "Send mail as" works until January 2027, and Google says new setups may already be restricted. If it works for you today, you can keep using it for now, but have a replacement ready before the date. Be careful of outside tools that promise to copy the feature. Google warns that third-party tools replicating send-as often require access to your email credentials or OAuth tokens. Giving a stranger your password to keep an old workflow alive is a poor trade.

If you use Google Workspace

This change does not affect Google Workspace "Send as" or your own aliases, according to Google. If your business address lives in a Workspace account, nothing here applies to you. It is aimed at people using a free Gmail account as the front end for an address hosted somewhere else.

Where our mailboxes fit

Colorado Internet Domains (coid.co) offers a full mailbox at [email protected] on about 39 Colorado city domains. There is no domain to buy. It works in any mail app over IMAP and SMTP with SSL, and in webmail, so it fits setups A, B and C above. A personal name is $19 a month, and trade names cost more.

The honest limits: you rent the address and do not own the domain. If you want an address on your own domain, buy one and use a mail host. Read Gmail vs a business email for how the two compare, and what a business email really costs for the numbers.

A simple plan before January

  1. Decide which of the three setups fits how you work.
  2. Set it up now, while the old method still works, so you can compare.
  3. Send a test to a friend and check that the reply comes back to the right address.
  4. Tell your team which app to use, and remove the old send-as setting once you are happy.
