the signup form checks your email address β a domain mailbox is the one it accepts
$10.46 once β a mailbox on your own domain β $1,000 in credits, plus a year of Claude Team
Three steps
- Buy the domain β Cloudflare Registrar: a
.comwith WHOIS privacy on by default. Name it like a company:yourcompany.com. A.comor.netreads as a business address. - Set up the mailbox β Zoho Mail, the free plan: one domain, up to 5 users, 5 GB each, on the web and in the Zoho apps. Create
[email protected]. - Apply for the credits β Claude for Startups, using that email address.
The DNS records β add them in this order
1 ownership TXT or CNAME from Zoho verify the domain first
