Email Warm-up

Both Reply.io and Maildoso offer email warm-up features to improve your email deliverability.

They work by gradually increasing your email sending volume and simulating human behavior, like opening emails and replying to messages.

This helps you build a good sender reputation with email service providers like Google Workspace and prevents your cold emails from landing in spam.
