I am a professional in the cold emailing industry, serving b2b clients in the US. Got something close to 20.000 inboxes that we manage, most GWS. We are looking to move now to SMTP, hence why I`m here.
I set up a mailcow as a mailserver that connects to my kumo. Its all integrated well, works fine - but I ran into 1 problem.
I`ve set them up on vultr and contabo - but I have an issue buying IPs and attaching them on my server. With vultr I can get max 3 IPS, with contabo more, but they are all ip blocks, ( ending is 141, 142, 143, etc ).
I want to be clean about this. Any recommendations on what to set up and where ?
Thanks.
