Sending too much email in a short period of time.Sending from a new IP address or domain.Reputation issues with an IP address or domain.The only idea I have left is to directly ask our customers to take out our messages from spam and put them into updates - really, great for our image and so professional.When your email is being throttled by mailbox providers, there are a few steps you can take. In most cases of throttling, mailbox providers send soft bounce error messages back to the sender, indicating that they are limiting the amount of email they will accept. I suspect that there is some major issue but I cannot find it.
#Ips were throttled by recipient server update#
I have also found out that when we test newly created Gmail account we are spam, but after 10-20 emails we start to be a promotion / update / main inbox on this particular account (without marking it as not spam) I have no idea how GMail identifies it since I tried to change absolutely every variable I have found.

We can clearly see a drop in our web page visits. well, it is 600-700 unique views and 70-100 unique clicks. For us it is a big issue as ~50% of our users use Gmail.īefore problems we had 1300-1500 unique views on average and 200-300 unique clicks (of total ~9000 subscribers). The problem started ~2 month ago without any obvious reason. So, everything seems to be ok (beside low domain reputation).
