There are several best practices to keep in mind: 1. Subject Line: Keep it engaging and relevant to increase open rates. 2. Timing: Donât wait too long to follow up, but donât be too aggressive either. 3. Value: Offer something new or valuable in each follow-up. 4. Clear CTA: Make sure each email has a clear and compelling call to action. 5. A/B Testing: Test different elements of your follow-up emails to see what works best.
