Over the years, I’ve changed domains a few times and managed multiple websites with their own emails. I always like everything in one Gmail inbox, as it makes it easy to keep track of things. Gmail has a handy “send mail as” feature, which lets you add multiple email addresses as aliases. This enables you to change the from and reply-to address. Below I’ll show you how to get past all the common errors.
How to add alias to Gmail
One of the reasons I’m documenting this is because Gmail’s instructions don’t mention everything, and then you wind up with errors. I typically find myself going through this every six months or so, and by then, I’ve forgotten all the little hiccups that can come up. I hope this helps save you some time.
Before we dive in, let me give you a use case scenario.
- [email protected] (my primary Gmail I use to manage everything)
- [email protected] (send mail as, alias #1)
- [email protected] (send mail as, alias #2)
Your primary Gmail can be a custom domain or a @gmail address. This depends on whether or not you are using G Suite. You can set up to 99 different “send mail as” and or alias email addresses. The alias email address can also be a @gmail address, it doesn’t have to be a custom domain.
This tutorial assumes you have 2-Step-Verification enabled on your Gmail account. If you don’t, you should.
If you’re using G Suite
If you’re using G Suite, you’ll need to follow a few steps first to add aliases within Gmail.
First, go to “Apps → G Suite → Gmail → End User Access.” Scroll down and enable “Allow per-user outbound gateways.”
Next, go to “Security → Settings → Less Secure Apps.” Enable “Allows users to manage their access to less secure apps.”
Note: This does make your account less secure, so beware of the changes. Google recommends setting up a domain alias in G Suite, which you can do. But this won’t let you pass the steps below, unfortunately. To change your “From” address, you have to set this up in Gmail, which requires an App password. Hopefully, this will change in the future.
After saving the above options, it will probably take 20-30 minutes to propagate the changes across to your Gmail. Grab a coffee and come back a little later to finish.
First, you will need to set up an app password. Go to Google App Passwords with your primary Gmail account.
You can pick anything, but I chose “Mail” for the app, and “Custom Name.” For the name, pick something you’ll recognize if you need to reference your app passwords later. I used “Send from [email protected]”
Copy the password they generate to your clipboard or somewhere temporarily as you’ll need it later.
In Gmail, go to the gear at the top right and click on “See all settings.” Click on “Accounts and Import.” Under “Send mail as,” click on “Add another email address.”
Enter the name and the email address for the second email address that you want to use as an alias. Leave the “Treat as an alias” option checked. Click “Next Step.”
Leave SMTP Server as smtp.gmail.com. Enter your primary Gmail email address in the Username field (not your alias email). Then enter your Google App password that you created earlier. Leave everything else and click “Add Account.”
If your credentials aren’t correct, you’ll most likely see a warning like this:
Authentication failed. Please check your username/password and Less Secure Apps access for [email protected]
A confirmation code will be sent to the email address you want to send mail as (use as an alias). Enter the code and click “Verify.” You can also click on the link in the email to confirm.
And that’s it! You now have multiple email addresses in Gmail, and you can send as another email address.
You can also change the defaults and the behavior of replies.
Another nice feature is that you can set up different default signatures for each email address. This way, when you respond, you can keep separate branding for each email address.

Now you can set up multiple emails in Gmail and manage everything under one inbox. Keep it fast and simple and straightforward; that’s the whole idea. It’s awesome for managing multiple websites, brands, changing domains, etc.
