"I had 600 subscribers I'd never emailed. I was scared I'd lost them. The cohort taught me to write like I was texting a regular — and the first email I sent got 43 replies."

What they said after
the cohort ended.

"I had a list of 400 people and I'd never sent a single email. Not because I didn't want to — because I was terrified. Week 1 of Inbox cured that."

"I recommend Inbox to every junior writer on my team. Not because it's basic — because it teaches the Tuesday-morning discipline that no marketing school covers."

"My re-engagement sequence brought back 47 subscribers who hadn't opened in six months. The instructor reviewed my draft live and caught one thing that would have killed it."

"The segmentation module alone changed how I pitch email strategy to clients. I went from "I do email" to "here's exactly how I'd sequence your list" in three weeks."
