A little bit about Proofy and what we do:
Proofy.io (https://proofy.io/) — bulk email cleaning service. With proofy you avoid bounces, catch-all, dead emails. You increase email deliverability, save your domain email, enhance the open rate. I suppose the audience is aware of many nuances in email marketing. Each email inbox has a sender reputation associated with our IP address of the sender. If you have a lot of bounces and spam, it affects our reputation as a sender. If this happens, then at best: your mail will not go to your inbox, at worst: email providers will blacklist your IP or domain, and this is not suitable for business.
Here is a question:
Much more our competitors increased service price, should we do the same step or no?
