Can I sign up using a Gmail or Outlook personal address?

Yes — personal email addresses are completely fine for Valid Email Checker signup. Gmail, Outlook.com, iCloud, ProtonMail, Yahoo, Fastmail, and every other real mailbox provider works the same way as a work domain. The only addresses we block are throwaway services (Mailinator, 10MinuteMail, GuerrillaMail, and a few thousand similar) — see why was my signup rejected with disposable email for the full mechanics there.

Why we mention personal addresses specifically

A lot of B2B SaaS products soft-block consumer email providers by sending the signup to a "request a demo" funnel or requiring a work email. We do not. The free tier is real and any real address can access it. A freelancer signing up with @gmail.com, a small business owner signing up with @outlook.com, and an enterprise user signing up with @theircompany.com all get the same 200 welcome credits and the same dashboard.

Faster path: Continue with Google

If you are signing up with a Gmail address, the fastest path is "Continue with Google" on the signup page. It does one-click signup using your existing Google session, skips the confirmation email entirely (Google has already proven you own the address), and lands you on the dashboard with the 200 credits already deposited. There is no password to set up — you sign in with Google in the future too. See is Google SSO supported for the full Google login behavior.

When a work address makes more sense than personal

Two scenarios:

• You are signing up on behalf of a team. Use a shared work address (e.g. marketing@yourcompany.com) or your own work address so the account is not tied to a personal mailbox that might be lost when someone leaves.
• You want to invite team members later. Team-member invites are tied to the owner account. If the owner is on a personal Gmail, it works fine, but a work address makes the audit trail cleaner for finance and compliance.
