SendGrid lookalike domains
Greyphish has recorded 88 domains that resemble SendGrid since February 2026, 35 of them in the last 90 days. They split between typosquats (58%) and combosquats (30%). .com carries 92% of them, out of 7 endings in all. The pace has slowed, with 1 in the last 30 days against 5 in the 30 before. The busiest week began 13 July 2026, with 22 new ones. 1 certificate for unregistered .com.ph names (registry wildcard) is excluded: the registry answers for any name under that ending, so nobody had to register one to get a certificate for it.

Where they are registered
For the 53 with a registrar in WHOIS (60% 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.
| Registrar | Lookalikes | Share | Type |
|---|---|---|---|
| NICENIC INTERNATIONAL GROUP | 11 | 20.8% | Retail |
| MarkMonitor | 10 | 18.9% | Brand protection |
| NameBright | 8 | 15.1% | Retail |
| NameSilo | 4 | 7.5% | Retail |

Greyphish is not affiliated with SendGrid. Domains listed resemble SendGrid by spelling; registration alone says nothing about intent. Counts cover domains first seen in public Certificate Transparency logs and ICANN zone files; domains that Greyphish customers watch are excluded.
