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. Usually, it's a handful of folks on your dedicated email marketing team who bear the brunt of this headache, which only makes things more challenging.

Now, here's the kicker: Amid all this chaos, we've noticed a common oversight among customers, and it's a big one. Many forget a crucial element for email success when switching to a new ESP: the proper warmup of your domain.

Time and time again, we see new customers sending emails to their entire list, often numbering in the hundreds of thousands, without considering the gradual approach that tells ISPs (like Gmail and Outlook) they can trust you.

What does this sudden onslaught of emails from a new domain to thousands of subscribers look like to ISPs? Yep, you guessed it—spam. And what does that do to your email-sending reputation? It tanks it.

Here at SmashSend, we're pumped to be tackling this problem and making the whole process a lot easier and less stressful for everyone involved.

Why should you warm up your list?

Sending your email campaign or newsletter to all your users without warming it up is an email-suicide. It's crucial to gradually establish a positive reputation for your IP address and domain to ensure your emails reach the inbox and avoid spam filters.
