Why use Gmail “Send mail as” aliases?
Why not just use Google G Suite? Which makes it easy to have email addresses that are within your domain:?
Because when compared to the cost of G Suite, it’s really cheap to do so.
G Suite costs $6 per month per user, and while you get a lot more with G Suite than just email addresses that are within your domain, if you need 6 such email addresses, it costs $36 per month.
For a solution using Gmail forwarding and aliases, the is $3 a month, for an unlimited number of email addresses within your domain.
How do you set this up?
Which services might cost?
First, let’s talk about what you have to pay for. You’ll need to subscribe to a mail forwarding service so that email inbound to your domain is properly delivered to your Gmail accounts.
For this tutorial we are recommending the email forwarding service of Forward Email.
Why? Because it works reliably, is fairly easy to setup, and costs only $3 a month.
For Forward Email, they have a free version, but I could not get it to work, so I subscribe to their lowest cost plan at $3 per month which allows for unlimited domains and unlimited email addresses within each domain.
Additionally, if you want a “catchall” email address for your domain, which I strongly recommend, it looks like you MUST subscribe to a paid plan.
Getting setup requires various steps, which are identified below. You can and should test steps where you can, and this too is identified below.
The list of steps are:
Setting up inbound email forwarding
- Setup an email forwarding service (Forward Email).
- This includes setting up what are called the Mail eXchange (MX) records within your DNS, which their instructions walk you through.
- Setup email forwarding within the service.
- Test that email forwarding works.
Step 1: Setup the email forwarding service
- Go to forwardemail.net, and sign up.
- Subscribe to their Enhanced Protection plan, at $3 a month.
- To setup your domain, select your domain, select the button Setup, and follow their instructions.
Step 2) Setup email forwarding within Forward Email
To setup your aliases, select your domain, select the button Aliases, and follow their instructions.
Step 3) Test that email forwarding works
You do this by sending email from an email address NOT within your domain, to the various email addresses which you’ve setup forwarding for, to ensure the email is being properly forwarded and delivered.
Step 4) Double check
By which I mean, until you’re absolutely sure that inbound email forwarding is working for you, do not proceed to step 4. If it’s not working, circle back.
Only after inbound email forwarding is fully functional should you move on to setting up your outbound SMTP relay for outbound email.
Setting up outbound Gmail SMTP relay
- Setup two factor authentication on your Gmail account.
- Obtain your Gmail SMTP relay app password.
- Start “Send as” setup within Gmail.
- Configure the SMTP relay within Gmail.
- Obtain and enter the Gmail SMTP relay verification code.
- Within Gmail, make your branded in domain email address the default.
- Test that mail sent from the Gmail account shows as From the alias, not the Gmail account itself.
Forward Email has a good YouTube video that shows how to do this, but they leave off two critically important things, which matter greatly.
While they do say to “make sure you have 2-factor authentication enabled”, they don’t then say “or else the next step will fail”.
They also omit my step 6 entirely, but it matters.

Step 7) Test
Test that mail sent from the Gmail account shows as From the alias, not the Gmail account itself. You need to do two tests:
7a) Send an email from the Gmail account to another email account and check the “From” field in the email header.
7b) Send a reply back to an email from another email account and check the “From” field in the email header.
