How to Avoid Outlook’s Junk Folder

Microsoft Outlook is a common email client that sometimes uses strict spam and junk filters.  Many factors impact Outlook’s spam filtering settings, but there are a few things you can do to help your campaign skip the junk folder and arrive in the inbox.

In this article, you’ll learn how to keep your campaigns out of Outlook’s junk folder.  


Engage Your Subscribers

Spam filter settings change frequently, and they pay attention to subscriber actions, like opens and clicks. If a subscriber marks your campaign as spam, Outlook’s filters will likely send your next campaign to the junk folder.

The best way to avoid this is to maintain a clean list of engaged subscribers who look forward to receiving your campaigns in their inboxes.

Add MailChimp Domains

Aggressive spam filters may label a legitimate campaign as spam or junk, even when you follow email marketing best practices. If this happens to you, ask your subscribers to import a list of MailChimp’s sending domains to their Safe Senders list in Outlook.

Set Up Custom Domain Authentication

Custom domain authentication improves delivery rates and tells spam filters your campaigns are coming from a reliable domain. If you send campaigns from an address associated with your own domain, set up authentication to help your campaigns arrive in the inbox.
