Start by verifying your email list. Remove invalid or outdated addresses regularly. Use double opt-in to confirm subscribers' emails. Avoid sending emails to inactive or unengaged users. Choose a reliable email service provider for better delivery. Ensure your sender domain is authenticated. Avoid spammy subject lines or content. Keep your email size small to prevent delivery issues. Test your emails before sending them to a full list. Use segmentation to target the right audience. Monitor your email analytics for bounce patterns. Consistent effort keeps your email list healthy and bounce rate low.
