Re-engaging inactive users is important in affiliate email marketing because keeping your list active can improve your email reputation. If someone hasn’t opened your emails in about 30 to 60 days, it may be a good time to reach out with a re-engagement message. You don’t need to send these types of emails too often, maybe once or twice a month is enough. Sending them too often might lead to more unsubscribes or spam complaints. A good way to go about it is to send a short email that reminds them of the value you bring. You can also offer a special bonus or ask if they still want to receive emails from you. This way, they can choose to stay or leave. It helps you keep a clean list and focus on those who are really interested. How would you approach inactive users if you were handling an email list?
