Warmup Inbox does allow Mailgun inboxes. Before connecting you need to

1. Have a properly configured Mailgun account

2. Locate your SMTP Credentials

1. Your SMTP credentials are different for each domain under Mailgun. For the inbox you are attempting to connect to the platform, you can find your default credentials by clicking through to your domain settings.

Once complete, here are the SMTP settings you should utilize.


Email Provider: MailGun Email

SMTP Settings:

SMTP Username: {{your default SMTP login}}

SMTP Password: {{your default SMTP password}}

SMTP Host:

SMTP Port: 465 (At times Port could also be 0)


Please note, that you can use the SMTP ONLY option only if you have purchased the Send-only plan.

SMTP & IMAP Option

With the Basic, Pro, and MAX plans, you can connect your MailGun account only alongside using an IMAP.

The IMAP username needs to be an email address under the domain you wish to warm up.

Instead of using the MailGun integration, you will connect your inbox using the SMTP & IMAP option.

Note: this option doesn´t work with Office365 inboxes as they don´t support IMAP.
