AuthenticSender replaces WordPress' default mail()<\/code> function with a configurable SMTP connection or the UseSend HTTP API, giving you control over how your site delivers email.<\/p>\n\n

Delivery Method<\/h4>\n\n

Choose SMTP<\/strong> (default) or UseSend API<\/strong>. Existing SMTP configurations keep working unchanged when SMTP is selected.<\/p>\n\n

SMTP Configuration<\/h4>\n\n

Enable or disable SMTP routing with a single checkbox. When disabled (and not using UseSend API), WordPress falls back to its default mail()<\/code> function. Configure your server connection with:<\/p>\n\n

    \n
  • Host<\/strong> - your SMTP server hostname or IP address<\/li>\n
  • Port<\/strong> - any valid port (1-65535), defaulting to 25<\/li>\n
  • Encryption<\/strong> - None, TLS, or SSL<\/li>\n
  • Authentication<\/strong> - optional username and password (stored encrypted with AES-256-GCM)<\/li>\n<\/ul>\n\n

    Provider Presets<\/h4>\n\n

    Select a preset from the dropdown and the host, port, and encryption fields are filled in automatically. Supported providers:<\/p>\n\n

      \n
    • Gmail<\/li>\n
    • SendGrid<\/li>\n
    • Mailgun<\/li>\n
    • Postmark<\/li>\n
    • Hostinger<\/li>\n
    • UseSend (host smtp.usesend.com<\/code>, username usesend<\/code>, password = your API key)<\/li>\n<\/ul>\n\n

      For a self-hosted UseSend SMTP proxy, use Custom and enter your proxy host with the same username\/API-key password pattern.<\/p>\n\n

      UseSend API<\/h4>\n\n

      Send mail through the UseSend HTTP API instead of SMTP:<\/p>\n\n

        \n
      • Encrypted API key storage<\/li>\n
      • Cloud hosting (app.usesend.com<\/code>) or self-hosted instance URL<\/li>\n
      • From, Reply-To, BCC, HTML\/text, and attachments are mapped to the API<\/li>\n<\/ul>\n\n

        Sender Identity<\/h4>\n\n

        Override the From name and From email address on outgoing emails when SMTP is enabled or UseSend API is selected. Enable Force Identity<\/strong> to apply From, Reply-To, and BCC even when using WordPress default mail.<\/p>\n\n

        Additional Headers<\/h4>\n\n

        Set global Reply-To (email and name) and BCC addresses. These apply when SMTP is enabled, UseSend API is selected, or when Force Identity is on. The BCC field accepts multiple comma-separated addresses.<\/p>\n\n

        Password resets, email confirmations, and similar sensitive messages are never copied to BCC, so reset links and verification tokens are not shared with the BCC address.<\/p>\n\n

        Test Email<\/h4>\n\n

        Send a test message directly from the settings page. AuthenticSender attempts delivery via wp_mail()<\/code> and returns a clear success or error message, so a misconfiguration never leaves you guessing.<\/p>\n\n

        Email Log<\/h4>\n\n

        Keep a database record of every email sent or failed. The log view includes:<\/p>\n\n

          \n
        • Timestamp, recipient, subject, status, and delivery method (SMTP, UseSend, or WP Default)<\/li>\n
        • Error message for failed deliveries<\/li>\n
        • Filter by All \/ Success \/ Failed<\/li>\n
        • Paginated table (20 entries per page)<\/li>\n
        • One-click Clear Log with confirmation prompt<\/li>\n
        • Configurable retention period (1-365 days); older entries are pruned automatically<\/li>\n<\/ul>\n\n

          Logging can be toggled on or off at any time from the Settings tab.<\/p>\n\n

          Security<\/h4>\n\n
            \n
          • SMTP password and UseSend API key stored encrypted using AES-256-GCM with WordPress AUTH_KEY<\/code> and SECURE_AUTH_KEY<\/code><\/li>\n
          • Unique (non-default, non-identical) authentication keys are required before new SMTP passwords or UseSend API keys can be saved; English and localized sample phrases are detected<\/li>\n
          • Self-hosted UseSend URLs must use HTTPS; localhost, private\/reserved IPs, and unresolvable hosts are blocked by default; HTTP redirects are disabled<\/li>\n
          • Global BCC skips password resets, email confirmations, and similar sensitive mail by default<\/li>\n
          • Email log redacts subjects for the same sensitive-mail patterns<\/li>\n
          • Plugin settings (including credentials) are not autoloaded on front-end requests<\/li>\n<\/ul>\n\n\n
              \n
            1. Upload the authenticsender<\/code> folder to the \/wp-content\/plugins\/<\/code> directory.<\/li>\n
            2. Activate the plugin through the Plugins menu in WordPress.<\/li>\n
            3. Go to Settings > AuthenticSender<\/strong> and choose SMTP or UseSend API.<\/li>\n
            4. Open the Test Email<\/strong> tab and send a test message to verify everything is working.<\/li>\n<\/ol>\n\n\n
              \n

              Do I need to disable WordPress' default mail() function?<\/h3><\/dt>\n

              No. AuthenticSender hooks into PHPMailer (SMTP) or pre_wp_mail<\/code> (UseSend API) automatically. When SMTP is enabled or UseSend API is selected, the default mail()<\/code> function is bypassed; otherwise it is restored.<\/p><\/dd>\n

              Can I use this with Gmail?<\/h3><\/dt>\n

              Yes. Select Gmail from the Provider Preset dropdown, then enter your Google account username and an App Password (not your regular Google password). App Passwords are generated at https:\/\/myaccount.google.com\/apppasswords<\/p><\/dd>\n

              How do I use UseSend?<\/h3><\/dt>\n

              Two options:<\/p>\n\n

                \n
              1. SMTP<\/strong> \u2014 Delivery Method = SMTP, Provider Preset = UseSend, username usesend<\/code>, password = your API key.<\/li>\n
              2. API<\/strong> \u2014 Delivery Method = UseSend API, enter your API key, choose Cloud or Self-hosted (and your instance URL).<\/li>\n<\/ol><\/dd>\n

                Where are the email logs stored?<\/h3><\/dt>\n

                Logs are stored in the WordPress database. No files are written to the filesystem. You can view, filter, and clear the log from the Email Log<\/strong> tab in the plugin settings.<\/p><\/dd>\n

                Does the plugin log all emails sent by WordPress?<\/h3><\/dt>\n

                Yes, when logging is enabled. This includes password reset emails, WooCommerce order notifications, contact form submissions, and any other email routed through wp_mail()<\/code>.<\/p><\/dd>\n

                What happens if I disable logging after entries already exist?<\/h3><\/dt>\n

                Existing entries are preserved. No new entries are written while logging is off. You can re-enable logging at any time or clear the existing log manually.<\/p><\/dd>\n

                Is my SMTP password stored securely?<\/h3><\/dt>\n

                Yes. Passwords and UseSend API keys are encrypted with AES-256-GCM using a key derived from your WordPress AUTH_KEY<\/code> and SECURE_AUTH_KEY<\/code> constants before being written to the database.<\/p><\/dd>\n

                When do From, Reply-To, and BCC apply?<\/h3><\/dt>\n

                They apply when SMTP is enabled or UseSend API is selected. Turn on Force Identity<\/strong> in Sender Identity if you want those overrides while using WordPress default mail.<\/p><\/dd>\n\n<\/dl>\n\n\n
