How Does IP Reputation Affect Email Deliverability and Spam Filtering? or What’s the Best Way to Impr

Oh man, IP reputation is *everything* when it comes to email deliverability. If yours is bad, yeah, your emails can straight-up get blocked—not just spam-foldered.

Tools like SenderScore and Talos are legit for checking your score. Also, MXToolbox has a free IP lookup that’s super handy.

If your open rates are tanking, I’d start by warming up a new IP slowly. And maybe clean your list—sending to inactive addresses murders your ip reputation.
