If you didn’t prepare for that, sending was excruciating around that time. As a result of the new ownership, they consolidated sending infrastructures between the two ISPs. Still, you can’t help but wonder… What started all of this?Įarlier in the year, a company named Oath took ownership of AOL and Yahoo. Basically, they’ve got their own grievances but they’re taking a hard line with the nonsense. The recipient server has either noticed an increase in volume, high rate of complaints, or spammer characteristics that trigger filters on the ISPs end. The majority of temporary failures get a returned message that says “Messages from certain IP temporarily deferred due to user complaints.” That generic response doesn’t give you much information at first, but it’s actually pretty straightforward. On our end, the most common reasons that AOL and Yahoo throttle senders are because the sender suddenly ramped up sending and aren’t following best practices.

Please note: in the event that a sending domain (and not the IP address) is blocked, that domain’s controller will be responsible for handling the delisting request.The thing is, no one ever talks about the annoyances bulk senders face day in and day out. SendGrid will still be happy to step in and assist with these delisting requests if the listing service requires the IP administrator to take action, or if the delisting form is too complicated. Dedicated IP addresses are only assigned to one account at a time, so we expect these users to take responsibility for all of the mail that is sent through their account. We ask that our dedicated IP plan users submit the initial delisting request if they discover their SendGrid IP on a block list. That said, we actively monitor these listings to ensure appropriate actions are taken to ensure email deliverability. The large majority of these blocklists do not have an impact on your deliverability, and often self-mitigate over time. Other deny lists: If you are using a shared IP plan, and you notice a block message from any other deny list based on one of our IP addresses, please note that blocklists are a natural part of sending email through shared IP Pools. You do not need to make an additional request through our support team.

Others are little more than an annoyance. Some, like the Spamhaus SBL, can bring your email program to a screeching halt. These days, there are hundreds, maybe thousands of block lists out there. Block list overviewĮnding up on a block list can be detrimental to your domain’s email deliverability.

Multiple blocks from the same provider can make it progressively harder to get delisted. Notice: If you request delisting from a blocking service, and don't do anything to change the behavior that caused the listing in the first place, you should expect to be blocked again. This guide gives recommendations for users to help avoid their email getting blocked. Many of the world's largest inbox providers use block lists to help them make filtering decisions.
