How often should I clean my email list to boost inboxing?

[Daniel]

Cleaning your email list is an important part of getting better inbox results. When too many of your emails go to inactive or fake addresses, email services may see your list as low quality. This can cause your emails to be marked as spam, even for people who want to hear from you. A good practice is to clean your list every few weeks or at least once a month. Remove contacts who haven't opened or clicked your emails in a while, and try to re-engage them first before deleting. Keeping only active and interested people on your list helps you get better open rates and protects your sender reputation. This is especially useful when sending affiliate offers, as inboxing is already more sensitive in this space. Have you tried regular list cleaning before sending your campaigns? It would be helpful to hear what difference it made for you or what methods you used.
