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?

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 @paxtonHow 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!
Best,
