Checks in with an inactive user or subscriber. Real examples from Ecommerce brands, captured from actual signups.
Re-engagement emails go to subscribers who stopped opening. They ask whether the reader still wants to hear from you, and clean the list if not.
"Do you still want these emails?" with a clear yes button is simple and effective.
A weekly digest or preference center keeps readers who only wanted fewer emails.
Unsubscribing people who never respond protects inbox placement for everyone else.
