The answer▼ Shrinking

Visits, year on year
-54%
Visits, last six months
-41%
Name searches vs October 2025
-7.2%

Every month I add up the Google visits to the 19 AI email marketing tool sites I track (DataForSEO estimates) and how often people in the US search for them by name (Google Ads). In October 2026 they got about 6.4 million visits. Brevo made most of the move in October 2026: it lost 2,627,033 of the market's 2,890,985 visits; without it, visits to the other sites fell 4.2% on September 2026.

The total hides very different stories: one site grew 69% in a year while another lost 76% of its visits. See who grew and who shrank, the visits month by month and the name searches, plus what I expect for November 2026.

Miles explains

Visits are lower than a year ago and lower than in September 2026, so the fall is still going. Name searches fell (-7%), but Google Trends interest in the term rose (+70%). The counted sites are losing ground; that does not mean interest in AI email marketing tool sites is falling.

2.Are people searching for AI email marketing tool sites by name?

Down 7% on October 2025; 1.4M name searches a month in the US

Fewer than before. People in the US searched Google for the names of the counted AI email marketing tool sites 1,442,990 times in September 2026, 7% fewer searches than in October 2025. Someone who searches a site’s name already knows it, so this is the clearest sign of people coming back on purpose. The term “ai email marketing tool” itself gets about 110 US searches a month (Google Ads, 12-month average).

Miles explains

Name searches are down, so fewer people are coming back on purpose. Better Google rankings will not fix that.

3.Which AI email marketing tool sites grew, and which shrank?

The five most-visited sites hold 83.7% of all visits; the ten most-visited hold 95.6%

The five most-visited AI email marketing tool sites get 83.7% of all visits, so one of them winning or losing a big Google ranking moves the whole total. Fastest grower over the year: Zeta Email, from 34,270 to 58,004 visits (+69%). Steepest fall: Omnisend, from 128,577 to 30,942 visits (-76%).
