It's not exactly too hard to read the Reddit post

Yeah, it's a bit hard to say whether they work or not. This is why I added my own website with real users interacting with confirmation emails
Basically, services like Folderly run their own private network of email addresses (on G Suite). Their service opens and interacts with emails, simulating real user behavior, to test and improve email deliverability and sender reputation.
I was really confident that I could maintain a good, positive IP reputation which I did. Until I got banned randomly.
The software that I built has features to combat end-user spam:
- Hourly Limit
- Spam Filter
- LLM-based Spam Filter (runs every 5,000 emails)
- Account Approval (where every user and their use case is verified by having a small chat with them first)
They did not provide any reason and just mentioned that they are unable to remove the block at the moment. Now, my replies are being ignored.
Only I am using the service (warmup + transactional emails sent through my other site) right now. I haven't started selling the service to others yet.
