People at Microsoft/Outlook are not receiving my emails from Mailspring

Help
#1

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 !
