People make two mistakes on follow-up nudges to recipients: A) They don't do it at all; B) They send long-winded emails that are exhausting to read. In this email, we sent a three-line email that anyone can skim in 10 seconds. We also used social proof to mention the audience of 1+ million that we have. You don't need a large audience to make this email work either. A few hundred engaged customers is still an extremely compelling offer... or, if you don't have any customers yet, get creative about how you can provide a compelling reason why the recipient should care.
