Most brands have heard of domain warmup. When you're setting up a new Klaviyo account, you don't just blast your entire list on day one - you start small, build gradually, and let inbox providers get to know you as a sender. That part tends to make sense to people. What doesn't get talked about nearly enough is what comes after that. Warmup isn't a one-time thing you do at the beginning and then forget about. It's a tool you can come back to - and for a lot of brands, it's something their account needs right now and they don't even know it. If your open rates have been sliding for months, if your deliverability feels off, or if you've just done a major list clean, a proper warmup might be exactly how you course correct. Because the conditions in your account today are not the same as when you first set it up - and acting like nothing has changed is how deliverability problems get worse without anyone noticing. This episode is also the natural follow-up to last week's conversation about list health. Cleaning your list resets your audience. A warmup is how you rebuild your sender reputation on top of that cleaner foundation. One without the other is only half the fix.
