What is email warmup?

Email warmup is a process where automated emails are gradually sent from a new or inactive email account to build its reputation with email providers. This helps prevent emails from landing in spam and improves deliverability.
Tools like MailReach or MailTester handle the warmup process by engaging with these emails in a natural way—opening, replying, and marking them as important—so email providers recognize the account as trustworthy and ready for outreach campaigns.

Don’t pay for features that dont make sense. Get real deliverability.

Warmy may sparkle, but your cold B2B emails deserve power, precision, and ROI.
