MailGun Configuration

How to Configure Mailgun

Configuring Mailgun for warmup can be a little tricky, considering it, like AWS SES, doesn't have an inbound IMAP.

We permit using SMTP from one provider and an IMAP from another. So you can use SMTP from Mailgun and IMAP from any other service you like.

Outgoing Mail (SMTP) Server

  • Server - (US) | (EU)

  • Port - 465 or 587

  • User - Your email

  • Password - Your API Key

Like AWS SES, SendGrid and SendinBlue, Mailgun does not provide IMAP. So you will need the IMAP of another mail provider like Google, Zoho, AWS Workmail, etc. A general rule is to use the IMAP of where you receive replies to your emails, but we place no restrictions on this. You can use whatever IMAP you prefer.
