Industry report / Email marketing platforms / August 2026
Mailchimp: named everywhere, first nowhere.
Choosing an email platform is one of the most AI-researched purchases in marketing: low stakes to ask about, high stakes to switch later. We recorded 1,005 assistant answers to the questions those buyers ask. The result is the most fragmented category we have measured, the clearest case of fame without a lane of its own, and the one category where the machines’ sources are not what anyone assumes.
Independent research. The brands featured did not commission or endorse this study. Commissioned audits never change published scores.
In this report
Executive summary
- Nobody owns this category. Everybody owns a lane. Six brands sit within six points of each other overall, while individual buying situations have near-total winners: Klaviyo and Omnisend for online stores, Kit and Beehiiv for creators, MailerLite and Brevo on price.
- Mailchimp, the most famous name in email, is named everywhere and first nowhere. It is the only brand present in all eight situations and it is ahead in none of them: level with the leader in three, clearly behind a specialist in the other five. When assistants search today’s web, its share drops further, from 16.7 to 13.3 percent.
- The legacy shelf is being cleared. GetResponse, twenty years in business, registers 0.1 percent of brand mentions. Constant Contact sits at 1.9 percent. No content operation is renting that visibility back.
- The answers here lean on comparison lists. In CRM and HR, the most cited sources are the leading brands’ own websites. In email marketing, four of the five most cited sources are “best tools” lists written by someone else: two affiliate review sites and the blogs of two smaller email tools. That changes what marketing money should buy.
Who the machines recommend
August 2026. From memory: 717 answers. With web search: 288 answers. Each brand’s situation-weighted share of brand mentions among the ten tracked brands; shares sum to 100% within each setting. Not the percentage of answers naming a brand, and not market share.
Finding 1: No category king, only situation kings
Percentage of recorded answers that include the brand in each situation, from memory. 90 answers per situation. Every value is shown, including zero.
| Brand | First tool | Best overall | Online store | Budget | Creator | Automation | Outgrown | Deliverability |
|---|---|---|---|---|---|---|---|---|
| Klaviyo | 48 | 99 | 100 | 10 | 2 | 96 | 71 | 73 |
| Mailchimp | 93 | 86 | 62 | 80 | 34 | 36 | 62 | 51 |
| Kit | 79 | 94 | 1 | 61 | 100 | 22 | 61 | 48 |
| MailerLite | 94 | 82 | 2 | 98 | 18 | 14 | 46 | 33 |
| Brevo | 88 | 70 | 21 | 98 | 0 | 20 | 54 | 17 |
| ActiveCampaign | 14 | 92 | 29 | 7 | 1 | 92 | 54 | 56 |
| Omnisend | 13 | 44 | 99 | 18 | 0 | 2 | 23 | 0 |
| Beehiiv | 7 | 38 | 0 | 13 | 100 | 0 | 29 | 4 |
| Constant Contact | 12 | 26 | 3 | 1 | 0 | 1 | 10 | 1 |
| GetResponse | 0 | 1 | 0 | 0 | 0 | 2 | 0 | 0 |
Situations: First tool = a first email tool for a small business, Best overall = the best platform overall, Online store = email for an online store, Budget = free or cheap plans, Creator = a newsletter as a creator, Automation = advanced automation, Outgrown = outgrowing the current tool, Deliverability = deliverability. Differences under 15 points are noise.
This is the cleanest situational segmentation we have measured anywhere: the machines have sorted the category into lanes and they rarely mix them. For a buyer, that means the first question they type decides which market they enter. For a vendor, it means growth is not a share-of-voice campaign; it is a decision about which of these eight doors to fight for, against a named incumbent at a known strength.
Finding 2: Mailchimp, famous everywhere, first nowhere
Two decades of brand building bought Mailchimp the only full-coverage profile in the category, and no throne. Where the money is, it trails the specialists badly: 34 percent with creators, 36 percent on advanced automation, 62 percent in e-commerce. And its share falls hardest of anyone when assistants read today’s web before answering, which means the current internet is actively steering the machines toward the specialists. Fame still opens the door; it no longer closes the deal. For a board, the strategic question is which two of these lanes Mailchimp intends to re-earn, because eight-at-mediocre is losing to one-at-total everywhere in this table.
Finding 3: The legacy shelf is being cleared
GetResponse has sold email marketing for over twenty years and appears in 0.1 percent of the machines’ brand mentions, clearing our noise floor in zero of eight situations. Constant Contact sits at 1.9 percent. The machines learned this category from the recent internet, and the recent internet has moved on. Search mode barely helps either brand, so nothing is currently renting that visibility back. This is what erasure looks like in the new channel, and it happened without either company doing anything wrong except standing still.
Finding 4: The answers lean on comparison lists
In our CRM and HR reports, the machines’ five most cited sources were all the leading brands’ own websites. Email marketing breaks the pattern: the two most cited sources are affiliate review sites, emailtooltester.com (60 citations) and emailvendorselection.com (53), and two of the next three are “best email marketing tools” articles on the blogs of smaller tools, sequenzy.com and sender.net. The ten brands’ own sites still carry 29 percent of all citations, but the top of the list belongs to whoever writes the comparison.
That changes what money should buy here. In HR, a vendor feeds the machines by publishing its own answers. In email marketing, your own pages are only half the job: being present and accurately described in a short list of specific comparison articles matters as much, and that list is not a guess. We observed it, per situation, in the citations themselves.

Citation occurrences, not unique answers or buyers. A citation shows a source was read, not that it caused the recommendation.
A recorded answer, in context
One answer, verbatim, from the archive behind this report. The study’s results come from repeated questions; a single answer shows the format buyers see.
“Best email marketing platform for an online store?”
Recorded test question
The right choice depends on your platform and needs, but here are the top options:
Claude via the Anthropic API, from memory, August 2026. Opening excerpt, not the entire response.
- Klaviyo: best overall for e-commerce
- Omnisend: built specifically for e-commerce
- Mailchimp: good for beginners, familiar interface
What we would do about it
A taste of the advisory layer, one line per seat at the table:
- If you own a lane (Klaviyo, Kit, Omnisend, MailerLite): your lane is your moat and your ceiling. The expansion play is the adjacent situation where you already show partial strength, and the citation map says exactly which reviewers guard it.
- If you are Mailchimp-shaped, famous but first nowhere: pick two lanes and re-earn them deliberately. Broad reminder advertising will not fix a position the machines re-decide with every answer.
- If you are being erased (GetResponse, Constant Contact): this is existential, and the comparison lists that feed this category’s answers matter as much as your own blog, especially where your profiles there are outdated or missing. Memory follows the sources; it never leads them.
- If you are small: Beehiiv reached 100 percent of creator answers in under five years. Total ownership of one situation is demonstrably achievable here, and worth more than 5 percent of everything.
The paid version is specific to you: your numbers per situation, the false claims AI makes about you, the exact sources to earn, priorities with owners and effort grades, and the tactics to skip. That is the audit, and the Program that carries the work out. To see the full depth on a real brand, read the sample audit of monday CRM built from our CRM dataset.
How we measured
ChatGPT, Gemini and Claude, queried through their official developer interfaces in August 2026, in the model tiers most buyers actually use. 1,005 recorded answers across eight buying situations, in two modes: from memory and with web search, reported separately. The design was frozen and hashed before the first question; measurement stability r = 0.94, and differences under 15 points per situation are noise, treated as such. These are controlled tests, not private customer conversations, and results can differ from the consumer apps.
Definitions, limits and the pre-registration protocol: methodology v0.2. The brands measured did not participate in, commission, or endorse this report, and we never sell placement in AI answers. Commissioned audits never change published scores.
Your brand, these numbers
If you sell email marketing software, your situational profile, the claims AI gets wrong about you and your citation map already sit in this dataset; a deep dive is available on request via contact. For any other category, the audit runs this exact measurement for your brand and competitors.
