Building an all-in-one cold email tool with automatic warmup would love early feedback!

Hey everyone! 👋

I'm building PostPalMail — a cold email platform that combines contact search, campaign sending, sequences, and automatic email warmup into one tool. Launching on Product Hunt this Wednesday (Sep 16).

The problem I kept running into (as someone who also runs a small marketing agency) was juggling separate tools for finding leads, sending campaigns, and warming up sender reputation — it gets expensive and messy fast.

A few things I'd love feedback on before launch:

1. Is automatic warmup something you actively look for in a cold email tool, or is it a "nice to have"?

2. What's the biggest pain point you've had with cold email platforms you've used before?

3. Anything you wish these tools did better?

Happy to answer any questions about the product too — genuinely trying to build something useful, not just launch and disappear. Thanks forHey everyone! 👋
