When your messages land in recipients' spam folders, it usually comes down to authentication, reputation, or content. Most causes are fixable from your DNS and sending habits.
Common Causes
- Missing email authentication. Without SPF, DKIM, and DMARC records, providers cannot verify your mail and treat it as suspicious.
- Poor domain or IP reputation. A new domain or a previously abused server IP can trigger filtering.
- Spammy content. Excessive links, all-caps subjects, attachments, and certain trigger words raise spam scores.
- No reverse DNS or mismatched server name. Sending from a hostname that does not resolve correctly hurts trust.
Steps to Fix It
- Add or verify your SPF, DKIM, and DMARC DNS records.
- Use the official mail server, mail.yourdomain.com, with authenticated SMTP on port 465 (SSL).
- Avoid sending large batches abruptly; warm up gradually.
- Keep subject lines honest and content clean.
- Test your message with a deliverability checker to see your spam score.
Check Your Reputation
If your domain or server IP appears on a blacklist, request delisting and resolve the underlying cause first. Persistent issues may require a dedicated IP.
