Summary

Emails often end up in spam folders due to various factors, with even seasoned senders occasionally encountering these issues. Key reasons include non-compliance with the CAN-SPAM Act, which mandates transparency in email headers and subjects, and maintaining a good sender reputation by ensuring recipients engage positively with emails. Additionally, keeping email lists clean prevents spam traps, while crafting effective subject lines avoids clickbait and excessive attachments that trigger spam filters. To mitigate these issues, senders can use mail testers, deploy authentication tools such as SPF, DKIM, and DMARC, and consider using dedicated sending services to enhance deliverability. Adhering to best practices, such as sending high-quality, relevant content and ensuring proper email list management, can significantly improve the likelihood of emails reaching recipients' inboxes.
