Complete Control. Zero Exposure.

From the moment you create an alias to your final reply, your real email remains completely invisible.

1. Generate a Smart Alias

Whether you don't trust a site or just want to ensure you control future mails, you set the rules. Define a destruct timer or max email count right in the address.

2. The Gatekeeper

MailGuard enforces your rules. If an alias is expired or has reached its email limit, the mail is rejected. Critical emails like OTPs/password resets always get through.

3. Your Inbox, Undisturbed

Safe emails arrive in your personal inbox (Gmail, Outlook, iCloud). We also aggregate newsletters into handy AI summaries, so you can track topics like #investing without the clutter.

4. The Invisible Handshake

Reply directly from your inbox. We strip your metadata, swap the headers, and send it from your alias. Even legitimate brands only see the alias, keeping your identity secure.

Stop Playing Whac-A-Mole with Spam

The difference between a cluttered mind and a commanded inbox.

Frequently Asked Questions

Do I need to own a domain?
For the Free plan, you can use our shared domain. For Pro plans, you have two options: 1) Bring your own domain (BYOD) by adding a few standard DNS records (MX, SPF, DKIM), or 2) Register a new domain directly through our dashboard.
How does replying anonymously work?
When you receive an email via an alias, the "Reply-To" header is set to a special MailGuard address. When you reply to that address from your personal inbox, we intercept it, strip your metadata, stamp it with your alias, and send it to the original sender.
Is my email data secure?
We operate on a "zero-knowledge" forwarding basis. Emails are processed in RAM and relayed instantly. We do not write emails to disk unless you specifically tag them for AI Summary (e.g., #investing), in which case both the message and its AI summary are stored encrypted and retained for 90 days so digest links continue working, after which sent items are automatically deleted.
What happens when an alias reaches its limit?
If you set a limit of `.14` (14 emails), the 15th email will be bounced with a standard delivery error to the sender. You will receive a notification (which doesn't count toward the limit) letting you know the alias has closed.
