Users are experiencing issues with emails from Discourse going to spam in Outlook but not in Gmail. ethhaqn reports that emails sent via Outlook consistently land in spam, despite passing a mail-tester check with an 8.7/10 score, noting missing list-unsubscribe and DKIM validation issues. haydenjames suggests using email delivery services like Postmark and references Microsoft’s support forums for similar problems. Jagster points out that newer top-level domains like .tech may be flagged by filters, though ethhaqn notes their domain isn’t the issue, humorously adding that their own notification email ended up in Outlook spam. Decorbuz confirms this is a known issue with non-Gmail providers and links to a Discourse community thread discussing the same problem, highlighting that Outlook is particularly strict with email filtering.
When receiving emails with Outlook, they always go to spam. However when I use Gmail, the emails don’t go to spam.
I ran a test with https://mail-tester.com, my result was 8.7/10:
Any help would be appreciated. Thanks!
I’ve had similar issues over the years. Sometimes it takes a while to build a good sender reputation. I often use services such as:
… or similar. Takes the pain out of delivery worries and there’s a free plan also.
Does your forum use some of new domains, not old ones like .com, .org or by countries? Most mail filters consider something like .co (pure one), .click, .talk etc as possible spam — and too bad, but filters are mostly right.
I don’t use Outlook, but can’t you whitelist senders there? But if you are wondering other users there is not too much to do if a forum has DKIM etc right. False spam alerts have been as old issue as spams that aren’t stopped.
Google seems to be quite generous and is letting thru almost anything nowadays.
Are you using the webmail client? Does the same issue also occur with other non-Gmail email providers like Yahoo! Mail and iCloud Mail?
It’s a well-known issue with email providers that aren’t Gmail. They like to discard emails sent by Discourse as junk/spam.
