I am looking for advice on getting my email marketing campaigns to gmail and outlook inboxes. For years I have been running a legitimate company that provides services to professionals. We acquire all of our customers by sending cold emails from the Mumara email program. The emails we send are very professional, text only emails aimed at starting conversations with the recipients. They are personalized with merge tags and spintags. We have a dedicated server with PowerMTA, multiple warmed up not blacklisted IPs with Senderscores of 98, and our DKIM, SPF, and rDNS settings are working 100%. We get 10/10 on mail-tester. Yet despite having an expensive email setup that is configured 100% correctly, we still get 0% deliverability to gmail and outlook based addresses. According to G-lock seed list tests our overall inbox placement is 35-40%. At least half of our email lists are G suite/Office 365 accounts, so we are missing out on a lot of revenue as a result of our emails being blocked. How can we get our emails into gmail and outlook inboxes?
