Hello, Since 7th of September we have noticed quite a deep drop of open rates to Gmail. Bounce message did not increase, sending domains or IP addresses are not blocked, general reputation on Gmail Postmaster Tools did not change much if any at all but, some senders experienced up to 50% drops in open rates. It's not related to one particular IP pool as well. The result is fairly clear, they ended up in spam folder. However, some clients started to complain that they are not able to see mail messages on their mailbox at all even though when our logs show general "sent" reply from Gmail: relay=aspmx.l.google.com[64.233.163.27]:25, delay=1.2, delays=0.13/0/0.51/0.6, dsn=2.0.0, status=sent (250 2.0.0 OK 1537051207 z2-v6si12644415ljb.127 - gsmtp)
The only probable idea I come up with is that we have gotten rid of 7 domains used throughout our infrastructure and since volume increased from one particular domain that we are using we could have gotten ourselves volume limited. We had few cases where senders confirmed that mail message appears only after searching the affected mailbox for the sending email address. However, some times I was not able to find test mails that are sent to my own personal mailbox as well. Anyone experienced this or would have any ideas what could be the case and how to solve this? Better yet, anyone here from Gmail who could contact me off-list for more details? Any ideas could help at this point as I am out of them. -- Best regards, Vytis Marčiulionis Email Deliverability Manager Mailerlite.com
