Email is perfect for nurturing leads and bringing back lost sales. Segment your list so messages feel personal. Send different emails to first-time buyers, repeat customers, or inactive users. Use strong subject lines to increase opens with value-focused copy to inspire action. Include a single clear CTA per email and make sure it links to a well-optimized landing page. Test everything: timing, layout, tone, and offer. You can also use behavior-triggered emails, like abandoned cart reminders or post-purchase follow-ups, to catch people at the right moment in their journey.
