Mailchimp in decline after Intuit acquisition, says SaaStr's Jason Lemkin
SaaStr founder Jason Lemkin argues that Mailchimp is in terminal decline following its acquisition by Intuit (August 2026):
Peaked post-acquisition. Mailchimp peaked at roughly $1B ARR just after Intuit acquired it for $12B, and Lemkin now sees the business flat-lining.
Stalled growth and layoffs. User growth has slowed to 0%, accompanied by a 17% cut to Intuit's workforce, with much of the deliverability team reportedly gone.
Product missteps. The marketing suite failed to gain traction, and AI products are described as limited, late, and offering little to no support for AI agents.
Monetisation under pressure. Freemium has been radically cut back to harvest the existing base, and Lemkin says even price increases cannot offset churn.
The wider signal. Lemkin frames it as more than an AI story: "the Age of AI is merciless to those that stand still."
