Self-hosted. Privacy-first. Fully yours.

Tempmails turns your WordPress site into a self-hosted temporary email
service. Visitors generate a random disposable email address, receive
messages in a real-time inbox, and discard them when done — all without
leaving your site.

Unlike third-party services, Tempmails runs entirely on your own server
and IMAP mailbox. You own the data, the domain, and the brand.

🔒 No third-party email APIs
📬 Real IMAP inbox — not a simulation
🎨 Material Design 3 UI — beautiful out of the box
⚡ AJAX-powered — no page reloads

Shortcode

Place the inbox anywhere on your site with one shortcode:

This renders the full inbox UI — email generation, copy button,
auto-refresh, message list, and message viewer modal.

Addon Ecosystem

Tempmails Core is frozen infrastructure. All new functionality is
delivered via addons using a documented, stable hook system — your site
never breaks on Core updates.

Available addon hooks cover: email generation, message routing, inbox
access control, multi-domain support, billing integration, and more.
See the Hooks section below for the full reference.

Privacy

Tempmails stores temporary email addresses in browser cookies to
maintain inbox sessions between page loads. No personal data is collected,
stored against user accounts, or transmitted to any external service.
See External Services below for details on the optional GitHub
ecosystem feed.

External Services

Ecosystem Feed (Optional — Default On)

Tempmails fetches a public JSON file from GitHub to display addon and
ecosystem information inside the WordPress admin panel.

What this connection does:

• Fires only when viewing Tempmails admin pages
• Retrieves only public, non-personal JSON content
• Transmits no user data, site URL, or any identifiable information
• Results are cached locally for 1 hour to minimize requests

Remote endpoint:
https://raw.githubusercontent.com/ubermensch-site/tempmails-ecosystem/main/ecosystem.json

Service provider: GitHub
Privacy policy: https://docs.github.com/en/site-policy/privacy-policies/github-general-privacy-statement

To disable this connection entirely, uncheck Ecosystem Feed under
Tempmails → Settings → General. Hardcoded fallback content is shown
instead — no requests are made.

Google Fonts

The frontend inbox loads the Inter and Poppins typefaces and the
Material Symbols icon font from Google Fonts CDN.

What this connection does:

• Fires only on pages where [tempmails_inbox] is rendered
• Transmits the visitor’s IP address to Google as part of a standard font
  request

Service provider: Google Fonts
Privacy policy: https://developers.google.com/fonts/faq/privacy

To avoid this (e.g. for GDPR compliance), dequeue tempmails-google-fonts
and load self-hosted font copies instead.
