To send from an alias in Gmail, add it under Settings, Accounts and Import, Send mail as, verify it, and then pick it in the From line when you write. An alias is a second address that delivers to the mailbox you already have, so replies come to the same inbox. It is a good fit for a role address like quotes@ or hello@. It is a bad fit for anything meant to make the reader think the email came from someone else.

Chidi runs a tile installation company in Austin on Google Workspace, using a domain he owns. He writes to home builders about bathroom and kitchen jobs. He wants the emails to come from quotes@ instead of his personal address, but he wants to read every reply in the inbox he already checks. This page follows his setup and the three checks that keep it credible.

What a send-as alias is, and what it is not

There are two things people call an alias. One is an alternate address on the same account: mail sent to quotes@ lands in Chidi's inbox, because both addresses are the same mailbox. The second is a separate account that you tell Gmail you can send from. Both show up under "Send mail as." The first is simple and the only kind this page recommends for outreach.

What an alias is not: it is not a new sender with its own history. It shares Chidi's mailbox, his sending limits and the reputation of his domain. If he sends too many emails from quotes@, the whole mailbox pays. So an alias is for presentation and sorting, not for getting more volume out of one account.

Adding the alias in Gmail settings

  1. If the address is on a Google Workspace domain, add it as an alias on your user first. This is done by an administrator in the Admin console, which for a one-person company is you.
  2. In Gmail on a computer, open Settings (the gear), choose See all settings, then Accounts and Import.
  3. Under "Send mail as," click Add another email address. Type your name as you want it shown and the address.
  4. Leave "Treat as an alias" ticked, since this is another address for the same mailbox, and click Next Step.
  5. Gmail sends a verification message to that address. Because it lands in your own inbox, click the link or type the code it gives you.
  6. Back in settings, choose how replies behave. "Reply from the same address the message was sent to" is the setting you want.

Now open a new message. Click the From name and choose quotes@. Send a test to yourself at a different address. If you change only the default From and not the reply-to, replies can still go to the original address, which Google notes on its help page, so check by replying to your own test.

What the recipient sees under the alias

On a properly set up alias, the recipient sees "Chidi Okeke" with the address quotes@tilecraft-austin.example, as if it were the main address. If the address is a separate account sent through someone else's mail server and not authenticated for Google, some clients show a notice. Google's help page says Outlook users might see something like "From yourname@gmail.com on behalf of othername@otherdomain.com," and Gmail can show "via" next to the sender. Those notices make a cold email look odd to a reader who is already deciding whether to trust you.

Authentication: the check that decides whether it lands

When the alias's domain is a Google Workspace domain, the outgoing mail goes through Google's servers, and it needs the same records as your main address. SPF for the domain must include Google, and DKIM must be switched on for that domain in the Admin console. Without it, the alias can fail DMARC and go to spam, even though the same email from your main address would not.

The test takes two minutes. Send a message from the alias to a Gmail address you control, open it, and choose Show original. Look for PASS next to SPF, DKIM and DMARC, with the DKIM domain matching your From domain. Chidi's first test showed DKIM passing but for a different domain, a sign that his DKIM key had been set on the wrong domain; he fixed it before sending a single cold email. The records themselves are explained in SPF, DKIM and DMARC for cold email.

Good uses and bad uses

A rule works here: an alias helps when it tells the reader something true, and hurts when it hides it. Good uses include a role address (quotes@, hello@, billing@) that tells the reader which part of the business is writing; a second address for a distinct offer line, such as commercial@ for builders and homes@ for homeowners; and a stable public address that survives a person leaving, so replies don't depend on whose mailbox it was.

Bad uses include inventing a person ("Sarah from Acme" when it is you), using several different names from one mailbox so the volume looks like a team, and sending as a domain you have not set up for authentication. The US CAN-SPAM Act requires the From line and sender information to be accurate, and a fake persona fails that and the reader's smell test. Sending from a second domain to protect your main one is a separate decision, covered in can you send cold email from your main domain.

Replies come to one inbox, so watch it

That is the main benefit. Replies to quotes@ arrive next to everything else. To keep them from getting lost, create a filter: in the search box, use the query deliveredto:quotes@tilecraft-austin.example, click the filter option, and apply a label ("Quotes") and a star. Then check that label first each morning. When you answer, Gmail picks the alias in the From line automatically if you left reply behavior on the default. The signature should match; see how to write a cold email signature and keep the physical address and opt-out line in it.

A January 2027 change to check first

Google's help page now states that starting in January 2027 Gmail will no longer support "Send as" for third-party email addresses, such as Yahoo or Outlook addresses. Send as for your own Gmail and Google Workspace addresses is not affected. If your alias depends on another provider's mail server, check Google's current page before building a process around it. If it is an alias on your own Workspace domain, as in Chidi's case, nothing changes.

If you are moving to a routine of regular sending, read how to send cold emails from Gmail for volume and warm-up. Pair a role address with a set of saved replies using Gmail canned responses, and queue sends for the right hour with Gmail schedule send.

One honest From address, on a domain you have authenticated, is a stronger setup than any number of clever ones.
