If you have not emailed a list in a long time, many people will not remember you. Sending a big promotion right away can cause spam complaints.
Start with a friendly re introduction, a gift and a clear way to stay or leave. Then remove anyone who does not engage.
Do it step by step
- Send a short email that reminds them who you are and why they joined.
- Offer a fresh gift for staying.
- Make unsubscribing easy.
- After a few emails, remove people who never opened.
