Hey,
All the people to whom I send emails and who use outlook/microsoft for messaging do not receive my emails when I send them from Mailspring.
When I send from another tool, such as AppleMail, I don’t have this problem.
I tried to delete my email signature, which is more elaborate than on AppleMail, but nothing works.
Can anyone help me find the source of the problem?
Thanks
Marie,
Were you able to find a solution in Mailspring sending emails to Microsoft Outlook users?

Hi,
It seems like the Open Tracking mode is detected as spam and put my email adress in blacklists… So be careful !
As you discovered, this is caused by Mailspring’s open tracking feature. When open tracking is enabled, Mailspring rewrites the invisible tracking pixel URL to go through link.getmailspring.com — Microsoft’s spam filters have become very aggressive about flagging messages that contain these redirect domains, and can end up blacklisting your address entirely. The fix is to turn off open tracking: in the composer, click the eye icon in the toolbar to toggle it off, or disable it by default in Preferences → Subscription. Glad you found the cause!
