Email warm-up was as simple as gradually sending more emails until you reached your daily volume target. Deliverability was much easier back then. Thus such an email-warming process was already enough.

That’s not the case nowadays. A proper email warm-up is now done by gradually raising the email volume AND having a high email engagement rate. Achieving both metrics demonstrates to the email providers that you’re a legitimate and interesting sender who deserves the inbox, not the spam folder.

Fortunately, email warm-up tools can help your email domain be recognized as trustworthy to email servers.

This blog has filtered the top 15 email warm-up tools to help level up your email marketing campaign. But before that, let’s explore what email warm-up is, how to do an email warm-up the best way (whether manual or automatic), and why it’s important.
