Sending email with Vercel Domains
In order to send emails with a custom domain, we need to:
- Buy the domain
- Purchase email hosting
- Configure DNS records on the domain
We will focus on steps two and three in this post. This post assumes you are using a domain purchased through Vercel and have
now CLI access configured.
You might be asking yourself:
Why can’t we just use Vercel (or other domain provider) for emails? Do I really need to pay more money?
The answer is yes, you do need to buy hosting. Namecheap has a pretty good description of why you need email hosting. Think of it as the same thing as website hosting, except for your emails.
GSuite is an alright product for sending emails from custom domains. To be clear, this tool is geared at enterprise businesses, so the UX leaves something to be desired.
Sign up for GSuite 💰💸
Confirm you own the domain.
In GSuite admin, go to Manage Domains. Click Add A Domain or Domain Alias.
To verify you own the domain, you will need to set a TXT record on your domain’s DNS settings.
now, it looks like the following:
List out your domains
1now dns ls
Using Google’s verification code, run the following command
1now dns add YOURDOMAINHERE.com @ TXT YOURGOOGLEVERIFICATIONSTRINGHERE
Press Validate in GSuite and Google will try to confirm you own the domain. It may take some time before this works, be patient.
Setup MX records.
After you prove you own the domain, it’s time to start forwarding along emails to Google.
This is also done via DNS records on your domain. Run each of these in your CLI.
1now dns add YOURDOMAINHERE.com @ MX ASPMX.L.GOOGLE.COM 12now dns add YOURDOMAINHERE.com @ MX ALT1.ASPMX.L.GOOGLE.COM 53now dns add YOURDOMAINHERE.com @ MX ALT2.ASPMX.L.GOOGLE.COM 54now dns add YOURDOMAINHERE.com @ MX ALT3.ASPMX.L.GOOGLE.COM 105now dns add YOURDOMAINHERE.com @ MX ALT4.ASPMX.L.GOOGLE.COM 10
Verify the MX records with GSuite.
Configure Gmail and GSuite.
Now, head over to Gmail.
Click on the settings gear, Accounts, and then “Add another email address”.
Enter in your new email and select “Treat as an alias”.
You may see the error:
Functionality not enabled. You must send emails through YOURDOMAINHERE.com SMTP servers when you send as you@YOURDOMAINHERE.com. However, this functionality is not available for your account. Please contact your domain administrator for more information.
To fix this error, hop over to the Gmail settings in GSuite for End User Access and enable “Allow per-user outbound gateways”.
Wait a few minutes and add the email address again in Gmail to resolve this issue.
