Hey there,
I'm expert in SMTP Configuration. I will configure server to cold email marketing. Most of freelancers do PowerMTA configuration. But these servers ended in Spamhaus blacklist after two three days or even within an hour. I have more experience in email delivery and issues fixing. I can configure server to send as you want and i can manage / monitor campaigns if you require. Its not Just about SPF DKIM DMAR rDNS and 10/10 at mail tester. There are some more thing has to be know about smtp configuration. I'm ready to provide better service for you. Lets get started.
Thanks
