Mailchimp lookalike domains
Greyphish has recorded 97 domains that resemble Mailchimp since February 2026, 5 of them in the last 90 days. Most of them (81%) are typosquats, a keystroke or two away from the real name. .com carries 97% of them, out of 4 endings in all. The busiest week began 6 July 2026, with 30 new ones. 4 certificates for unregistered .ph, .com.ph names (registry wildcard) are excluded: the registry answers for any name under those endings, so nobody had to register one to get a certificate for it.

Where they are registered
For the 55 with a registrar in WHOIS (57% of all). Brand-protection registrars mostly hold defensive registrations made by brands themselves, so a domain there is more likely the brand's own than an imitation.

| Dynadot | 16 | 29.1% | Retail |
| GoDaddy | 5 | 9.1% | Retail |

The 10 most recent, written with [.] so they cannot be clicked. The brand's own domains and registrations held by brand-protection registrars are left out. A lookalike resembles Mailchimp; it is not necessarily malicious, and none of these is a claim about who registered it or why.
