Ever since I started using Mailspring, my recipients have been reporting that my messages are going to spam. Why is this, and how can I fix it?
Link tracking and read receipts both work by attaching images and/or links which point to the getmailspring.com domain. Unfortunately, some email services assume that the presence of any links or images from this domain means the message is a marketing email.
If you’re experiencing this problem, disable link tracking and read receipts. To learn how, see: Disable Link Tracking/Read Receipts
