The January edition of this report estimated changes across 11 platforms. This edition is built differently: CdpHub has now read the public integration documentation of 44 customer data and engagement platforms and recorded every integration each one documents. The directory holds 6,691 listings across 2,365 tools, each linked to the page it came from. The figures below are counts from that directory, not estimates, so they aren't comparable with January's.

This report looks at coverage from the tool's side: which tools the platforms agree on, where the big catalogs have gaps, and which partner products dropped out of the market while the platforms kept listing them.

Key findings

Coverage is concentrated in a small core. 90 tools are documented by ten or more platforms and 30 by twenty or more. 1,653 of the 2,365 tools (70 percent) are documented by just one. A few tools are connected by nearly everyone, and a long tail is connected by a single platform each.

The big catalogs agree on the core. Of the 25 most connected tools, Treasure AI and RudderStack document all 25, and Tealium, Hightouch, mParticle, Fivetran Activations, Amperity and Lytics 24 each. The differences between platforms are in the long tail.

Catalogs outlive their partners. In this edition CdpHub removed 96 listings for 88 partner products that have shut down or been folded into an acquirer, from Delighted (June 2026), Gauges (April 2026) and Acquia Lift (January 2026) back to ClickEquations (2011). Most were still on the platforms' own integration pages.

2026 brought a wave of renames. Census became Fivetran Activations, Totango became Odie, CrossEngage became Spotler ActivatePro, SAP Emarsys became SAP Engagement Cloud and Treasure Data became Treasure AI.

What we count. Every platform names its integrations differently. Segment and RudderStack call them sources and destinations, mParticle calls them inputs and outputs, and Tealium has tags that run in the browser and connectors that deliver data server-side. This report calls each one a listing: one integration documented on one platform's site. A tool is the third-party product on the other end, such as Meta Ads, Snowflake or Braze, whichever way the data flows. A platform that documents both a browser tag and a server-side connector for the same vendor has two listings but one tool, which is why 6,691 listings reduce to 2,365 tools. Of those listings, 4,000 send data out (what most CDPs call destinations), 1,910 bring data in (sources) and 781 do both.

The head is small. The 90 tools on ten or more platforms are about 4 percent of all tools, and the 30 on twenty or more about 1 percent. The tail is large: 1,653 tools are on exactly one platform. That doesn't mean a tail tool can't connect elsewhere. It may work through a webhook, a warehouse or the vendor's own integration that other platforms haven't documented. It does mean that for tail tools, the platform you choose decides whether the connection is documented at all.

The core: what every large catalog covers

The most connected tools are ad platforms, warehouses and the big CRM and commerce systems. Meta Ads is documented by 38 platforms, Google Ads and Snowflake by 35 each, Amazon S3 by 33, and BigQuery, HubSpot and Salesforce by 30 each.

Here is how the 20 largest catalogs cover the 25 most connected tools (the same list as the CDP Market Landscape 2026 report's chart, with a tool's audience, conversion and pixel listings counted as one product):

Klaviyo13Several storage tools, ad platforms and Google's tags
NICE8Its catalog is built around customer service

A gap in this table is a gap in the documentation, not proof that the two tools can't connect. A missing tool may still work through a webhook, the warehouse or the partner's own integration, so ask the vendor and get the answer in writing.

The tail: where catalogs differ

Beyond the core, catalogs diverge fast. The share of a platform's tools that no other platform documents ranges from 7 percent for RudderStack, 8 percent for DinMo and 9 percent for Fivetran Activations to 49 percent for Segment, 59 percent for Tealium, 60 percent for NICE and 67 percent for Klaviyo. Tealium's tail is mostly vendor tags, and Klaviyo's is largely e-commerce apps from its marketplace.

By category, the tail is longest in Security & Privacy, where 81 percent of tools appear on only one platform, and in Analytics & BI (74 percent) and Customer Support (73 percent). Advertising has the most tools of any category, 380, and 66 percent of them are on one platform. Customer Data Platform has the smallest share of single-platform tools, 36 percent: when CDPs connect to one another, several platforms tend to document the same pairing.

For a buyer, this means headline catalog size says little. What matters is whether the specific tools in your stack are documented, in the direction you need.

Retirements: partners that disappeared

Platforms add integrations faster than they remove them. This quarter CdpHub checked every partner product that showed signs of retirement, such as an acquisition, a dead or redirected website or documentation that stopped changing years ago, and found 96 listings for 88 products that no longer operate. It removed them. Some shut down outright, and others were folded into an acquirer and are no longer sold under their own name. 6sense's Drift integration, which 6sense has kept switched off since the 2025 Drift breach, was also removed. The 96 listings came from Tealium (61), Segment (24), mParticle (4), ActionIQ (3), and RudderStack and Adobe Experience Platform (2 each), and most are vendor tags for ad and analytics products from the 2010s. Most of their pages on the platforms' own sites were still live when CdpHub checked them in October. Products whose end CdpHub couldn't confirm, such as Leanplum, which CleverTap is moving to its own platform, stay listed until it can.

Older closures in the list include Kahuna (2019), Netmining (2019), Polyvore (2018), Nextag (2018), Drawbridge's ad business (2018), Chango (2017) and TellApart (2017), and acquired products such as Clicktale, SessionCam, DataXu, Convertro and Custora.

Some products are partly retired but still listed, because their integrations still work:

  • Amazon Pinpoint. AWS ends Pinpoint's endpoints, segments, campaigns, journeys and analytics on October 30, 2026. Sending SMS, voice, email and push continues for existing customers, so the three Pinpoint listings stay, with notes on what ends.
  • Drift. Salesloft announced a gradual sunset of Drift on March 5, 2026 and refers its clients to 1mind. Drift still runs for existing customers, so six Drift listings stay.
  • Xandr. Microsoft closed its Invest DSP on February 28, 2026. Microsoft Curate still documents Xandr segments and the universal pixel, and Monetize still serves publishers, so the Xandr listings stay.

CdpHub will remove these when the integrations stop working.

Renames and ownership changes in 2026

The directory shows each platform and tool under its current name, with the old one alongside, and old links keep working.

  • Census is now Fivetran Activations.
  • Totango is now Odie.
  • CrossEngage is now Spotler ActivatePro.
  • SAP Emarsys is now SAP Engagement Cloud.
  • Treasure Data is now Treasure AI.
  • ActionIQ now documents under Uniphore, and BlueVenn under Upland.
  • Among the tools the platforms connect to, Ninetailed is now Contentful Personalization, Selligent is Marigold Engage and Outbrain became Teads. Older renames now applied in the directory: SmarterHQ is Wunderkind Audiences, Welcome is Optimizely Content Marketing Platform, Usabilla is GetFeedback Digital, Clubhouse is Shortcut, CheetahMail is Cheetah Digital and BlueHornet is Mapp.

What buyers should watch

Check your stack, tool by tool. List every tool that must send data to the CDP or receive it, then look each one up in the CdpHub directory for each finalist. The core is covered almost everywhere, so the decision usually turns on two or three tools in the tail.

Ask about retirements. A platform's catalog can keep listing a partner long after it stops working. Ask each vendor how it marks deprecated integrations and how much notice it gives.

Watch the dated changes. If you use Amazon Pinpoint's endpoints or campaigns, Drift, or Xandr Invest audiences through a CDP today, plan the move now.

How we count

  • Scope: 44 customer data and engagement platforms, and every integration with a third-party tool that each documents on a public page, as of October 2026. The platform's own SDKs, APIs, tags and products are not counted.
  • Listings and tools: a listing is one integration a platform documents, whatever the platform calls it (source, destination, tag, connector, input or output). A tool is the third-party product on the other end. A platform with several listings for one tool, such as a tag and a connector, counts once for that tool. Renamed products are grouped under their current name.
  • Most connected tools: the 25 tools documented by the most platforms; a tool's audience, conversion and pixel listings count as one product.
  • Retirements: a partner product is removed when its own company, its acquirer or reliable reporting shows it no longer operates, or when the platform has switched the integration off. Removed listings are hidden, not deleted, and the evidence is kept.
  • Sources: every page was read within its site's robots.txt rules. Counts change as catalogs change; the live directory is the reference.
