Sending IP blocklisted on UCEPROTECT2

I am investigating why our emails are going into the spam folder in Gmail and I discovered that we are on the UCEPROTECT2 blocklist which is a "listing of multiple IP addresses of your ISP / host / domain provider". I take it this is Hubspot since we send emails from Hubspot via our connected Domain. DKIM etc is correctly set up.

Can anyone give me more information on this?

Sending IP blocklisted on UCEPROTECT2

Hi @Thompson_DHARMA,

Thank you for reaching out to the Community!

I found an article for you "Understand email blocklists" that will provide you with more information and give your preventative steps.

I also found this similar thread "Sendability issues... Hubspot send IP is blocklisted" where the solution from @paxton might be of interest.

Here is a great post from @paxton "How to bring up a snowballing open rate" that can help you improve your deliverability too.

If you'd like more information, I would recommend connecting with HubSpot Technical Support, as Support is included in your subscription and they will be able to provide real-time assistance for this matter, including hopping on a screenshare if necessary.

I hope this helps!

Have a great day!
