A Guide to Whitelisting Mailgun on Various Email Platforms

whitelisting mailgun

Securing your email communications against unwarranted spam and malicious malware is of paramount importance. One effective way of ensuring that legitimate emails reach your inbox is through whitelisting. Whitelisting is a process wherein certain trusted IP addresses or domains are given permission to send emails to your inbox without being flagged as spam. One such trusted source could be Mailgun, a reputable email delivery service.

If you are using Mailgun to manage your email communications, it’s essential to whitelist its IP and domain to ensure seamless delivery of emails to your inbox and those of your correspondents. In this blog post, we’ll take a detailed look at how to whitelist Mailgun on Microsoft 365, Gmail, and Outlook – three of the most popular email platforms.

Whitelisting Mailgun on Microsoft 365

Microsoft 365 (formerly known as Office 365) offers robust email filtering options to keep unwanted emails at bay. However, to allow legitimate emails from Mailgun through, follow these steps:

  1. Login to your Microsoft 365 Admin Centre:
    • Navigate to the Microsoft 365 Admin Centre and log in with your administrator credentials.
  2. Access Mail Flow Settings:
    • Once logged in, head to the ‘Admin centres’ section and select ‘Exchange’. Here, click on ‘mail flow’ on the left-hand navigation panel.
