Vendors with Suppression List Management

1 vendor in our catalog is built around suppression list management — including Dotdigital. A further 30 offer it alongside their main job. 31 of the 31 claims cite a page on the vendor's own documentation.

Core means the capability is central to what the product is; supported means it is genuinely offered but is not what the product is for. Most grades come from three separate AI passes over the vendor's documentation, with only a majority verdict recorded; the rest were set by hand. If you already own a tool listed under "also offer", check it before buying a dedicated one.

Most of the vendors here sit on the Customer Engagement Platform, Email Delivery, Personalization shelves. That matters when a capability crosses categories — a CDP and a customer engagement platform can both offer suppression list management without being the same kind of tool.

Shortlist from the core list rather than the full one. 1 vendor is built around suppression list management; the 30 below that offer it as a secondary job, which is usually enough if you already pay for one of them and not enough if this is the reason you are buying. We rank by what the evidence supports, never by company size or spend with us.

This page is it, and it is generated from the catalog rather than maintained by hand — a vendor added tomorrow appears here on the next build if the evidence puts it here. 31 of 31 claims link the vendor's own documentation, and a blank cell means no verdict either way rather than "no".
