Step-by-step Mailgun Setup

1. Sign up for Mailgun.com

2. Check your email inbox to verify the email address

3. Login to Mailgun, Click on Sending > Add New Domain

4. If your domain is companyname.com, you can either set up the main domain or subdomain with Mailgun.

A. Main domain:

If you are adding the main domain, it should not be used with Gsuite, or any other email provider.

Subdomain:

To set up the subdomain with Mailgun, you can type ANYTHING_HERE.companyname.com
Examples:
- mg.companyname.com
- replies.companyname.com
- support.companyname.com

B. Please set up the domain or subdomain under US, not EU.

C. Click on Add domain

The next screen that you're taken to will ask you to add DNS records to your domain. Leave this screen open for the next step.

5. Now log in to your DNS records based on where you get the domain and add the 5 DNS records.

To add the 1st TXT record:

Click on DNS > Records

Click on + Add Record

A. Type: Select TXT from the Type menu options.

B. Name: DO NOT INCLUDE THE ROOT DOMAIN

Depending on the subdomain you are trying to set up:

If you are trying to set up mg.companyname.com, the host name will be mg
If replies.companyname.com, the host name will be replies
If you are setting up a main domain like companyname.com, the host name will be @

C. Content: Same for everyone
Paste the following record: v=spf1 include:mailgun.org ~all

D. Click on Save

To add the 2nd TXT record:

Click on + Add Record again

A. Type: Select TXT from the Type menu options.

B. Name: It's a bit tricky, but the key here is to copy everything from the beginning until the subdomain part, DO NOT INCLUDE THE ROOT DOMAIN

Everyone's 2nd TXT record hostname and value is different.

Examples:

Copy mx._domainkey.helpdesk as the hostname

Copy mailo._domainkey as the hostname

C. Content: Head back to Mailgun and copy the 2nd TXT record here highlighted in the screenshot below.

Content: Paste the 2nd very long copied TXT record here.

For mg.companyname.com, the host name will be email.mg
For replies.companyname.com, the host name will be email.replies
