Real-time email verification for WordPress. Block invalid, disposable, and risky emails before they enter your forms, lists, or checkout.<\/div>\n

Trumailo<\/strong> verifies every email address submitted to your WordPress site \u2014 in real time, with one drop-in plugin \u2014 and stops fake, throwaway, mistyped, and risky addresses before<\/em> they touch your CRM, mailing list, or order pipeline.<\/p>\n

Why bother<\/h4>\n
    \n
  • Spam signups inflate your list and tank deliverability.<\/li>\n
  • Disposable inboxes (Mailinator, 10MinuteMail, etc.) never convert.<\/li>\n
  • Typo’d emails (gmial.com<\/code>, yhaoo.com<\/code>) are lost forever.<\/li>\n
  • Role addresses (admin@<\/code>, info@<\/code>) hurt sender reputation.<\/li>\n<\/ul>\n

    Trumailo catches all of those at the form, with a friendly inline message.<\/p>\n

    Works out of the box with<\/h4>\n

      Features<\/h4>\n
        \n
      • Server-side blocking<\/strong> \u2014 survives JavaScript-disabled bots; the rejection happens during form validation.<\/li>\n
      • Real-time inline validation<\/strong> \u2014 debounced typing check with “did you mean” suggestions and accessible status badges.<\/li>\n
      • Per-status policy<\/strong> \u2014 choose what to block: invalid, disposable, risky, role addresses, or anything below a quality threshold.<\/li>\n
      • Whitelist \/ blacklist<\/strong> \u2014 skip the API for trusted internal domains; always reject specific bad ones.<\/li>\n
      • Cache<\/strong> \u2014 repeat verifications served instantly from local transients (configurable TTL).<\/li>\n
      • Fail-open by default<\/strong> \u2014 if the API is unreachable, submissions go through (configurable to fail-closed).<\/li>\n
      • Verification log<\/strong> \u2014 opt-in, with optional email-hashing for GDPR compliance and configurable retention.<\/li>\n
      • Dashboard<\/strong> \u2014 counts of allowed, blocked, cached, and per-day trend.<\/li>\n
      • REST endpoint<\/strong> \u2014 for custom front-ends and third-party integrations (\/wp-json\/trumailo\/v1\/verify<\/code>).<\/li>\n
      • Multisite-aware<\/strong>, i18n-ready<\/strong>, GPL-2.0<\/strong>.<\/li>\n<\/ul>\n

        Getting started<\/h4>\n
          \n
        1. Install and activate the plugin.<\/li>\n
        2. Get an API key at https:\/\/trumailo.com.<\/li>\n
        3. Settings \u2192<\/span> Trumailo \u2192<\/span> paste the key.<\/li>\n
        4. Done \u2014 every supported form on your site is now verifying emails.<\/li>\n<\/ol>\n

          External services<\/h3>\n

          This plugin connects to the Trumailo email-verification API to determine whether each submitted email address is deliverable. The API is provided by Trumailo (https:\/\/trumailo.com), the same vendor that publishes this plugin.<\/p>\n

          What the service is and what it is used for<\/strong><\/p>\n

          Trumailo is a real-time email-verification API. It checks an address for syntactically-valid format, MX records, disposable \/ role \/ catch-all signals, and (where the recipient mail server cooperates) an SMTP-level deliverability probe. The plugin uses it so your site can reject invalid, disposable, and risky addresses before they enter your forms, lists, or checkout.<\/p>\n

          What data is sent and when<\/strong><\/p>\n

            \n
          • The plugin sends the email address being verified<\/strong> to https:\/\/api.trumailo.com\/v1\/verify<\/code> over HTTPS, together with your API key in the Authorization: Bearer<\/code> header. This happens every time a supported form is submitted with a value the plugin hasn’t already cached.<\/li>\n
          • The plugin sends a lightweight request to https:\/\/api.trumailo.com\/v1\/account<\/code> to read the calling key’s remaining monthly credits. This is used to populate the credits gauge on the plugin dashboard and is polled at most every 5 minutes.<\/li>\n
          • No other personal data, form fields, page URLs, or visitor identifiers are transmitted.<\/li>\n
          • Verification results are cached locally in WordPress transients to minimise repeat API calls; you can configure the TTL and toggle full-email vs hashed-email storage in the plugin settings.<\/li>\n<\/ul>\n

            Service provider, terms, and privacy<\/strong><\/p>\n

            • Terms of Service: https:\/\/trumailo.com\/terms<\/li>\n
