Reducing email rejections involves a combination of technical setups and strategic planning:
Verify your email list regularly to remove invalid addresses and reduce hard bounces. Use spam-check tools to identify and modify content that might trigger spam filters. Implement proper email authentication protocols like DMARC, DKIM, and SPF to ensure emails are not flagged. Maintain a balanced send frequency to avoid overwhelming recipients and triggering spam defenses. Monitor blacklists regularly to ensure your IP address is not listed.
