WORKSPACES
First 10 teams only — locked forever at this rate.
Most auth providers block disposable email domains.
A testing domain of your own (like @yourcompany-qa.com) isn't on disposable-email blocklists — so your CI never fails because of the email domain.
Includes 1-on-1 concierge setup with the founder.

FAQ
Is the free tier really free forever?
Yes. No credit card and no trial period. Without an API key, one sender can reach 5 different inboxes a day; a free key (sign in with GitHub) removes that limit for inboxes under your key's prefix, and only your key can read them. The free tier uses a shared domain with 30-minute TTL — suitable for individual developers and open source projects.
What's the shared domain risk?
The free tier routes email through zerodrop-sandbox.online, a shared domain used by many developers. Some identity providers flag shared disposable email domains. For production CI pipelines, a Workspace's own domain avoids this.
How does Workspaces onboarding work?
After payment, the founder reaches out personally within 2 hours to set up your domain: one you own, with its nameservers pointed at our Cloudflare account, or one we register for you. Mail to any address on it lands in inboxes only your key can read, kept for the retention you choose. First 10 teams get the founding rate locked forever.
Can I self-host?
Yes — the Cloudflare Worker is fully open source. See the self-hosting guide.
What payment methods are accepted?
All major credit and debit cards, UPI (India), and local payment methods via Dodo Payments.
Is there a Data Processing Agreement available?
Yes — email [email protected]. See our full security posture on GitHub.
