Cleaning your email list is something that should be done regularly if you want better results from your email campaigns. If you keep sending emails to people who no longer open them, it can affect your deliverability. Email providers may start sending your messages to spam. A good idea is to clean your list every one to three months. This means removing inactive contacts, checking for invalid addresses, and making sure your subscribers are still interested. You can try to re-engage people before removing them by sending a simple email asking if they still want to stay on your list. Keeping your list clean also helps you focus on the people who are actually paying attention. It saves money too, especially if you’re using an email service that charges based on the size of your list. Have you ever thought about how often you should check your own list?
