Why Are My Emails Going to Spam?

Email deliverability is determined by thousands of factors, but they generally fall into three categories: authentication, reputation, and content.

• Authentication Failures: If your domain lacks valid SPF, DKIM, and DMARC records, inbox providers cannot verify your identity and will route your emails to spam to protect users.
• Poor Sender Reputation: Sending emails to invalid addresses (high bounce rate) or receiving too many spam complaints will destroy your IP and domain reputation.
• Content Issues: Using aggressive sales language, broken HTML, misleading subject lines, or linking to blocklisted domains can trigger spam filters.

How to Improve Email Deliverability

Improving deliverability requires a holistic approach. First, ensure your technical foundation (SPF/DKIM/DMARC, rDNS) is perfect. Second, implement a double opt-in process to ensure your subscribers actually want your emails. Third, regularly clean your list using an email validator to remove inactive or bouncing addresses. Finally, monitor your engagement metrics—if users aren't opening or clicking, stop sending to them.
