The best marketing automation and ABM platforms, graded on sending discipline and what they can actually evidence
A marketing automation platform sends more email under your domain than the rest of your stack combined, scores your leads with a model it calls AI, and holds your entire contact database for as long as you pay. Those three facts are the buying question, and the index grades all 15 platforms on them from public artifacts. This page publishes what each one is willing to say.
Assessed 2026-08-29. 249 vendors indexed across the whole index, 15 in this category.
This category documents its integrations 11.4 times more readily than the AI it leads with. 80 percent of the 15 platforms document integration depth at A or B. 7 percent can evidence that the scoring and personalization they call AI would be missed if it were removed, and 7 percent say what happens to your contact database when the contract ends.
Not one of the 15 vendors clears all 6 of the axes this category is decided on. 4 of them carry a D on at least one. The axes a platform demonstrates in a sales cycle, integrations and segment fit, are the best documented on the board. The two a buyer meets at renewal, whether the AI is real and whether the database comes home, are the worst.
What 15 vendors actually disclose
6 of the seventeen index axes decide a purchase in this category, and every vendor in it carries a grade on all 6. A grade of A or B means a buyer can check the claim without contacting the vendor. A D records that nothing was found in public sources on the verification date, which is far more often an absence of disclosure than a defect in the product.

Deliverability and Sending Discipline
The operational craft of sending: warmup, rotation, volume governance, spam rate monitoring, and what happens when reputation degrades. |
7 of 15 | 47 percent | 2 |

Data Privacy Posture
GDPR and CCPA posture: lawful basis, data subject rights handling, DPA availability, subprocessor disclosure. |
5 of 15 | 33 percent | 1 |

AI Centrality
Whether AI is the product or a feature veneer. The removal test: peel the AI label off, and does anything sellable remain? |
1 of 15 | 7 percent | 1 |

Exit and Data Portability
What happens when a customer leaves: completeness of data export, rights to enriched or licensed data after termination, deletion commitments, and auto renewal mechanics, graded from published terms and documentation. |
1 of 15 | 7 percent | 1 |

Commercial Transparency
Whether a buyer can budget without a sales call. Published pricing graded on completeness, not on the price itself. |

Read the AI row against the integration row. Every platform in this lane now describes itself as AI powered, and almost none can show what the AI changes. Integration, by contrast, is documented in detail, because it is the thing a prospect asks to see in the demo.
The 7 platforms that document how they send under your domain
7 of 15These are the platforms graded A or B on Deliverability and Sending Discipline, ordered by that grade and then by how many of the other five decisive axes they also document. It is not a ranking of campaign features, template libraries or ad network reach, and it is not a ranking of price. It is a ranking of what a buyer can verify about the sending, the data and the exit before signing. Several are indexed primarily as CRMs and appear here because they sell a campaigns module on top of the system of record.

Every grade on this page carries a source basis, and on the deciding axis the mix is worth stating plainly: 15 Vendor Published. That means the picture rests on what vendors publish about their own sending infrastructure, consent handling and data terms. The index records those as claims and dates them; it does not treat a stated commitment as an audited one, and it does not fill a gap in either direction.
Read the full methodology →6 questions the published materials will not answer
Where the index found nothing to grade, these are the questions that close the gap. Put them in the evaluation, and get the answers in writing rather than on a call.
Are we sending from our own domain with SPF, DKIM and DMARC alignment enforced by default, and what does the platform do when our complaint rate rises?
Marketing volume is where a domain reputation is won or lost, and the mailbox providers enforce faster than any regulator. A threshold you learn about during the incident is not a threshold.
How is marketing consent captured, stored per contact and honored across regions, and can you produce the record for one disputed address?
The test of a consent system is one record on demand, months later. A checkbox on a form is not a consent system until the record behind it can be shown.
Which CRM objects and fields does the platform read and write, in which direction, and who owns the fields it creates?
Account based marketing only works if the account record is shared. A one way sync is a data export with a delay.
Show me a lead score and explain, in terms a marketer can act on, why it is that number and what would change it.
This is the axis the whole category grades worst on. If the answer is a description of the model rather than a demonstration on your data, the AI is a label.
What do we get back at termination: contacts, consent records, engagement history and segments, in what format, and how long do we have?
The contact database and its consent history are the least reproducible asset a marketing team owns, and this category documents the exit almost nowhere.
What is the price at our contact count, our send volume and our seat count, and which of those three is the meter that moves?
Marketing automation is priced on contacts, on volume or on seats, sometimes all three, and the tier that fits today rarely fits after the first import.
Common questions
What features should B2B teams look for in an account based marketing platform?
Five, and only the first is on the feature comparison. Sending discipline under your own domain, with authentication and complaint thresholds enforced by default, which 7 of the 15 platforms in the GTM Tech Index document at A or B. Consent capture and regional handling that can produce a single record on demand, documented by 5. A CRM integration that reads and writes the account record in both directions, documented by 12. Lead and account scoring that can be shown working on your data rather than described, which 1 of 15 evidences. And an exit clause that returns contacts, consent records and engagement history in a usable format, which 1 documents. Intent data feeds, ad network reach and template libraries matter, and they are also what every vendor in the category will demonstrate unprompted.
How do pricing models for account based marketing platforms compare?
Three meters, and the one that moves is the one to model. Contact based pricing charges for the size of the database, so the bill grows with every import whether or not the contacts are marketed to. Volume based pricing charges for sends, which fits campaign heavy teams and punishes nurture. Seat based pricing charges for users and usually hides a contact or send cap inside each tier. Account based platforms add a fourth: credits for intent data or advertising, metered separately. 4 of the 15 platforms in this lane publish pricing complete enough to model any of that without a call, and 9 publish something checkable. On this page's shortlist SalesExec publishes real prices. The index's pricing transparency page shows how this category compares with every other, and it is not flattering.
Which index tracks account based marketing vendors?
The GTM Tech Index tracks 15 marketing automation and account based marketing platforms, each graded on the same seventeen capability axes from public artifacts, with a verification date and a source basis on every figure. It is independently maintained, no vendor pays for inclusion or placement, and changes to vendor capability, pricing and compliance posture are logged as they are verified.
Do marketing automation platforms actually use AI to score leads?
Every platform in this lane says so. 1 of 15 passes the index's removal test, meaning the product would lose something a buyer would notice if the model were switched off, and 13 describe AI features without evidence that they do work a rule could not. That is the widest gap between claimed and evidenced AI in any lane of the index. Ask to see a score explained on your own data, in terms a marketer can act on, and grade the answer yourself.
The GTM Tech Index is an independent editorial reference. No vendor pays for inclusion, placement, or rating. Grades reflect the public evidence on the verification date and change as vendors publish more. Compliance postures are assessed from published sources and public records; the index is not a law firm and nothing here is legal advice. Vendors who believe a record is wrong are invited to point the index at published documentation through the contact form on any page, and corrections are logged in the change log.
