Mailspring not sending emails correctly

Description

When I send an email from the Mailspring app in Linux (Arch Linux, Gnome Desktop), I hear the woosh sound but the recipient isn’t receiving the email.
I have tried using my Gmail account (connected via IMAP) and my Outlook account (Connected via Outlook connection).
Furthermore, the email is in my GMail and Outlook Sent folders in their web apps.
I have also tried sending emails between the two accounts but still have the same issue.

  2. Sent an email
  3. Check if received
