I have a cold email marketing agency & we just built a cold email SAAS (took us a year). Only issue is we can’t open port 25 we’ve reached out to 10 different ISPs.
I’m using a software development agency that can’t figure it out but when I message others they say they can get Hetzner, Digital Ocean, or Vultr to open it up. How is this possible?
