Setup custom email addresses
Using Mailgun's MX server with your custom domain for emails
⚠️ This post is archived.
It had been a while that I owned my domain and was wondering if I could switch
all my email communication to a custom email address [email protected].
Apart from owning the domain, the only requirement which remains is the that of an
MX (Mail Exchange) server which can route my emails for me. This is pretty handily done via
services like GSuite and Outlook
but I am not in a stage to shell out a few bucks for a custom email address. This
is when Mailgun enters the scene with its free offering of 10000 e-mail transactions
per month which sounds more than enough.
Here are the steps for anybody seeking solution to a similar problem.
Get your favorite domain name
Get a domain name from a domain registrar like
Namecheap. There is
no way you can get this for free (legally at least).
Setup your Mailgun Account and DNS Zone file
After signing up for
Mailgun (you might need to go through an activation process
with the customer care explaining your need), you must add a new custom domain
and make appropriate entries. Here is part of the
Zone File which contains
the Resource Records (
RR) to be managed.
; MX Records
@ 3600 IN MX 10 mxb.mailgun.org
@ 3600 IN MX 10 mxa.mailgun.org
; TXT Records
@ 3600 IN TXT "v=spf1 include:mailgun.org ~all"
YOUR_DOMAIN_KEY_HOST 3600 IN TXT "k=rsa; YOUR_RSA_KEY"
YOUR_RSA_KEY are available in the
dashboard. Most Domain registrars provide a comfortable GUI interface to add
Setup Routing via Mailgun
Setup a new Route which in simple words means directing your new email id to an existing one.
A sample rule is:
This will forward all mails to “[email protected]” to “[email protected]”.
With this, you have successfully setup to receive emails at a custom domain.
Setup SMTP Credentials
To allow sending email, you need to setup custom SMTP credentials under your Mailgun domain. See How do I start sending email.
Setup GMail custom SMTP account
Gmail allows you to add custom emails to your account which you can send e-mail as right within Gmail itself. See Check email from other accounts with Gmail.
The settings needed are:
SMTP Server: smtp.mailgun.org
PORT: 587 (TLS)
Username: [email protected]
Password: <Same as used during setting up SMTP credentials in Mailgun>
You should receive a verification email at the account where you chose to forward
your emails (
[email protected]) before you start sending emails as
Voila! Start sending emails around, send me one at [email protected]!
