The most crowded top of any category (May–Jul 2026). # Best Marketing Automation Tools in 2026: Which Ones Does ChatGPT Actually Recommend? [**Yonjun Jeong**](https://www.linkedin.com/in/yonjun-jeong-7bb05a65/), Co-founder · Last updated: 07.13.2026 ## What this article covers This list ranks tools by **how strongly ChatGPT actually recommends them** (DECA Score), measured every week for 10 weeks (May 10 – July 12, 2026; ChatGPT GPT-5.4, US). Marketing automation has the **most crowded top of any category we track** — six tools within 12 DECA points. > **Summary for citation:** In DecaGEO's data (ChatGPT GPT-5.4, US, Marketing Automation category, week of July 12, 2026), Braze is #1 (DECA 100), followed by HubSpot Marketing Hub (97.8) and a three-way tie for #3 between Iterable, Klaviyo, and Adobe Marketo Engage (92.5 each), with Customer.io close (88.2). The #1 spot has been held by three tools over 10 weeks — Braze (7), HubSpot (2), Adobe Marketo Engage (1). Rankings use a fixed prompt set no customer can customize, so they are free of marketer bias. > **Key takeaway:** No category is as deep at the top as marketing automation — six tools within 12 points, and a three-way tie for #3. Braze leads, but the field is bunched enough that weekly order shifts easily. ## Top 10 marketing automation tools ChatGPT recommends — at a glance | # | Tool | DECA Score | Consistency (10 weeks) | | -: | --------------------------------------------- | ---------: | ------------------------------- | | 1 | Braze | 100.0 | #1 in 7/10 weeks · top-5 all 10 | | 2 | HubSpot Marketing Hub | 97.8 | #1 in 2/10 weeks · top-5 all 10 | | 3 | Iterable | 92.5 | top-5 in 9/10 | | 3 | Klaviyo | 92.5 | recent surge — top-5 once in 10 | | 3 | Adobe Marketo Engage | 92.5 | #1 once · top-5 all 10 | | 6 | Customer.io | 88.2 | top-5 in 8/10 | | 7 | ActiveCampaign | 77.4 | top-5 in 2/10 | | 8 | Agentforce Marketing | 75.3 | tracked 8 weeks | | 9 | Brevo Marketing Platform | 60.2 | tracked all 10 | | 10 | Salesforce Marketing Cloud Account Engagement | 36.6 | tracked all 10 | *Table 1: Marketing automation tools ranked by DECA Score, week of July 12, 2026, with 10-week consistency. Source: DecaGEO, ChatGPT (GPT-5.4), US.* ## Why this ranking is unbiased Unlike GEO tools where marketers configure or approve their own prompts — which bakes the operator's bias into the result — DecaGEO runs a **fixed, identical set of recommendation prompts that no customer can add to, edit, or approve.** The moment a marketer can shape the prompts, the output reflects what they *want* AI to say, not what AI actually recommends. Because DecaGEO's prompt set is locked and consistent every week, this ranking measures the market — not any brand's preference. ## The most crowded top in AI recommendations The gap from #1 (Braze, 100) to #6 (Customer.io, 88.2) is just \~12 points, and three tools — **Iterable, Klaviyo, Adobe Marketo Engage** — are tied at #3 (92.5). Three different tools have held #1 over 10 weeks (Braze 7, HubSpot 2, Adobe Marketo 1). Braze is the front-runner, not a runaway. ## The top 10, in detail ### 1. [Braze](https://decageo.ai/products/braze/category/marketing-automation?week=2026-07-12) — DECA 100 The front-runner — #1 in 7 of 10 weeks. Cross-channel customer engagement. ### 2. [HubSpot Marketing Hub](https://decageo.ai/products/hubspot-marketing-hub/category/marketing-automation?week=2026-07-12) — DECA 97.8 The closest challenger — #1 in 2 weeks, essentially tied on 10-week average (94.0). ### 3. [Iterable](https://decageo.ai/products/iterable/category/marketing-automation?week=2026-07-12) — DECA 92.5 Tied for #3, top-5 in 9 of 10 weeks. ### 3. [Klaviyo](https://decageo.ai/products/klaviyo/category/marketing-automation?week=2026-07-12) — DECA 92.5 Tied for #3 on a **sharp recent surge** — top-5 in only 1 of 10 weeks, so momentum, not yet durable. (See [Klaviyo vs Mailchimp](https://decageo.ai/docs/best-tools/klaviyo-vs-mailchimp).) ### 3. [Adobe Marketo Engage](https://decageo.ai/products/adobe-marketo-engage/category/marketing-automation?week=2026-07-12) — DECA 92.5 Tied for #3, top-5 all 10 weeks, took #1 once — the most established at the #3 line. ### 6. [Customer.io](https://decageo.ai/products/customer.io/category/marketing-automation?week=2026-07-12) — DECA 88.2 Just outside the tie, top-5 in 8 of 10 weeks — developer-friendly automation. ### 7. [ActiveCampaign](https://decageo.ai/products/activecampaign/category/marketing-automation?week=2026-07-12) — DECA 77.4 A popular SMB automation/CRM tool, in and out of the top five. ### 8. [Agentforce Marketing](https://decageo.ai/products/agentforce-marketing/category/marketing-automation?week=2026-07-12) — DECA 75.3 Salesforce's marketing offering, tracked 8 weeks. ### 9. [Brevo Marketing Platform](https://decageo.ai/products/brevo-marketing-platform/category/marketing-automation?week=2026-07-12) — DECA 60.2 The Email Marketing leader appears mid-list here. ### 10. [Salesforce Marketing Cloud Account Engagement](https://decageo.ai/products/salesforce-marketing-cloud-account-engagement/category/marketing-automation?week=2026-07-12) — DECA 36.6 Formerly Pardot, rounds out the top 10. ## What this means for you * **Depth means opportunity — and instability.** Six tools within 12 points; a strong week can lift you several spots, and gains reverse easily. * **Surge vs durability.** Klaviyo is tied #3 on momentum (top-5 once); Adobe Marketo tied #3 on a decade-long track record. * **Two names anchor the top** — Braze and HubSpot; the reachable fight is #3–#6. ## FAQ **Which marketing automation tool does ChatGPT recommend most?** Braze — #1 in 7 of 10 weeks (DECA 100), narrowly ahead of HubSpot (97.8). **Why are three tools tied for #3?** Iterable, Klaviyo, and Adobe Marketo all scored 92.5 — the most bunched top of any category. **Is Klaviyo really top-3?** By score this week, yes — but top-5 in only 1 of 10 weeks, so it's a recent surge, not an established rank. **What is DECA Score?** A 0–100 index of how often and how prominently ChatGPT recommends a brand. [Full methodology →](https://www.decageo.ai/methodology) **Are these rankings stable?** Membership is fairly stable, but the order is the least settled of any category. **Is this a features review?** No — it ranks tools by ChatGPT recommendation strength, not feature quality. ## How we measure DecaGEO runs a consistent set of Marketing Automation recommendation prompts each week through ChatGPT (GPT-5.4, US region) and records which brands are named and how prominently. * **DECA Score** is a 0–100 index of recommendation strength within a category. * **Data window:** 10 weeks, May 10 – July 12, 2026.
