Here's why you need to use an email warm-up tool:



Think of email warm-up as a shield for your emails. It makes sure your emails get delivered and reach the right people in their inboxes. When you use it, email service providers (ESPs) will trust you more and won’t mark your emails as spam.



Here are 5 ways an email warm-up tool helps you:



1. More emails in the inbox → your emails will land where people actually see them.

2. Higher open & reply rates →  more people will read and reply to your emails when they see them in their inbox.

3. Fewer bounced emails → you'll avoid those annoying delivery failure messages.

4. No blacklisting → your email domain will be safe and won't get a bad reputation with email providers.
5. Beat spam filters → your sending volume will stay consistent, so your emails won't be treated as spam.
