How does Automated IP and Domain Warmup Feature work?

Having helped numerous customers transition from their old email service provider, one thing's clear: switching to a new email marketing software can be a real hassle. It's time-consuming, stressful, and, quite frankly, it can feel like a mess.

From dealing with CSV file downloads to wondering if you can transfer your engagement history and ensuring that unsubscribes and suppression lists get moved, there's a lot on your plate.
