Is Temp Postal better than Mailinator?

For privacy, yes. Mailinator inboxes are fully public — anyone who knows the address can read the mail. Temp Postal gives you a private inbox with AES-256 encryption, 48-hour retention, and no public listing.

Is Mailinator safe for verification codes?

Risky. Because Mailinator inboxes are public, anyone can read your verification codes and take over the account you just created. Never use Mailinator for anything you care about.

Does Mailinator have an API?

Mailinator's API is a paid, enterprise-focused product. Temp Postal's REST API is available on Premium ($4.99/mo, 1,000 calls) and Business ($49/mo, 50,000 calls) with full documentation.

Can I switch from Mailinator to Temp Postal?

Instantly — no migration needed. Generate a Temp Postal address and use it wherever you used Mailinator. Private by default, no public inbox.

Why is Mailinator blocked on so many sites?

Mailinator's domains are the most blocklisted disposable domains on the internet because they're famous and entirely public. Temp Postal rotates 20+ domains to stay deliverable.

Temp Mail vs Mailinator: Private Beats Public

The Mailinator security problem, plainly

If you verify an account with a Mailinator address, anyone else can read that verification email too — and take over your account. Mailinator is fine for reading public newsletters; it is unsafe for anything with a password.
