This! this is exactly what i was looking for, I've been sending cold outreach emails and I'm always skeptical these are going in spam 😭 will definitely be using this!
Whenever I think of a cold email campaign, I always think about how many of those emails would end up in the spam box. Thank you for bringing this up. Congratulations on the launch @fabian_maume
@fabian_maume Since you support Google, I'm curious: how did you circumvent the crackdown on automated enrichment emails? If it's something you can share of course 🙈 Most providers I see in the articles closed because of it: https://www.dataflo.io/blog/emai....
