Frequently Asked Questions
What exactly does email warmup do?

How long does it take to see results from a warmup tool?
With tools like Instantly and Warmy, you might start seeing better inbox placement within a week or two. However, it can take a few weeks to a month to see really strong and consistent improvement in your domain reputation.
Can I send cold emails right after using a warmup tool?
