Frequently Asked Questions
about IP warming

What is IP warming?

IP Warming is the process of preparing an IP address to build a positive email sending reputation with email providers.

Most of the time, IP warming is done by gradually adding email volume over several days and weeks according to a schedule.

Today, there is a more smart and automated way of warming an IP using an IP warming service like MailReach.

MailReach warms your IP automatically with a complex algorithm that handles dozens of parameters to maximize your sending reputation.

You just need to connect your sending address to MailReach and let it do the job the best way.

MailReach gradually starts email conversations with thousands of high reputation addresses to raise and maintain your reputation and deliverability.

Is IP warming and IP warm up the same?

IP warm up and IP warming are similar but IP warming is the most relevant way of calling it.

By definition, an IP warm up is a process done only before sending email campaigns to prepare for sending. Unfortunately, warming up an IP only before sending and stop warming once sending the campaigns is a bad pratice.

You can warm up an IP during 1 month, then stop the warm up, start sending and land in spam 2 months later. Warming only before sending does not immunize against spam.

IP warming is important before and during your campaigns.

Having a constant engagement (getting your emails opened, read, marked as important, removed from spam) helps you stay away from spam during your campaigns.
