15 Best Email Warm-Up Tools (Tested And Compared)

Why Do You Need an Email Warm-Up Service?

When sending cold emails or running email campaigns, hitting the inbox instead of the spam folder is crucial. New or inactive email accounts often have low sender reputations, leading to poor deliverability. Email warm-up services help gradually build this reputation by simulating real email interactions, ensuring that your messages reach their intended recipients. Without a proper warm-up, your emails could be flagged as spam, reducing your chances of successful outreach.
