Hi all, Does anyone have used tools like AiSDR or Artisan? Any pros and cons?

Not these 2 but a similar product (a YC company) covering prospecting, custom copy for each lead, sending email + linkedin, analytics etc Pros 3% reply, 1.5% demos saves a ton of time and money better copy vs human (for 2k leads) No warm up tool required Cons Rare bit of hallucination in writing Mailbox delivery issues / burning (not specific to this tool though) happy to connect with the founders
