Description

Powerful, simple, and built for real-world WordPress sites that must have reliable email.

Route all your WordPress emails through a trusted mailer—either your own SMTP server or a seamless Gmail OAuth connection managed by Thinkit—no messy app setup required.

Key Features

  • Two Mailer Modes
    • Google / Gmail via Thinkit
      • One-click “Connect to Google” flow.
      • No Client ID / Secret or app passwords needed on the site.
      • Emails are delivered through the Gmail API, not generic SMTP.
      • Sent messages appear in the connected Gmail account’s Sent folder.
    • Other SMTP
      • Use any SMTP provider: standard mail server, hosting SMTP, transactional email service, etc.
      • Built-in presets for popular providers (Gmail SMTP, SendGrid, Mailgun, Office 365, SMTP2GO).
      • Customize host, port, encryption, auth, username, and password.

Gmail via Thinkit (OAuth) Benefits

  • Seamless OAuth flow
    • Site owner clicks Connect to Google → authenticates on thinkitmedia.com → grants access → returns to WP with “Connected as your@email”.
  • Safe token handling
    • Access and refresh tokens are stored on Thinkit’s broker, not in your site’s database.
    • Automatic token refresh; no manual maintenance.
  • Gmail-native delivery
    • Uses the official Gmail API for sending.
    • Higher trust and deliverability compared to basic PHP mail.

Smart Email Logging & Debugging

  • Dedicated “Email Logs” screen
    • View a list of recent emails WordPress attempted to send.
    • Each entry shows:
      • Time
      • Status (success / failed)
      • Recipient(s)
      • Subject
      • Message excerpt
      • Error (if any)
      • Context (Frontend / Admin / WP-Cron)
  • Log retention control
    • Choose how long to keep logs: 30 / 60 / 90 days.
    • Old entries are pruned automatically.
  • Flush logs instantly
    • One click to clear all email logs.
  • Last error surface
    • Most recent error is surfaced at the top of the Settings and Logs pages for quick troubleshooting.

Built-in Test Email Tool

  • Send Test Email from the Logs page:
    • Quickly confirm deliverability.
    • Detailed result message shows:
      • Whether it succeeded or failed.
      • Which mailer path was used, e.g.
        Mailer used: gmail_api or Mailer used: smtp.
    • Optional SMTP debug output (for Other SMTP) written to error log when enabled.

Admin UI & Workflow

  • Top-level “SMTP Mailer” menu
    • Easy access from the main WordPress admin sidebar.
    • Two clear sections:
      • Settings
      • Email Logs
  • Activation & License status
    • Activation box at the top shows:
      • Activated / Not activated
      • Masked license key preview.
    • License powers:
      • Plugin updates via Thinkit’s update system.
      • Gmail / OAuth features.
  • Context-aware settings UI
    • When Gmail is selected:
      • SMTP-specific fields (host, port, encryption, auth, username, password, SMTP debug, provider presets) are hidden so the screen is clean.
    • When Other SMTP is selected:
      • All SMTP options are shown for full customization.

Email Identity & Consistency

  • From Email & Name
    • Set a global “From email” and “From name.”
  • Force From
    • Option to force all emails to use this From address/name, regardless of what individual plugins try to send.
  • Designed so Gmail mode pairs well with the connected Gmail address for maximum consistency and deliverability.

Under-the-Hood Reliability

  • Gmail API sending via Thinkit broker
    • Client plugin sends structured email data to Thinkit.
    • Thinkit’s Gmail broker calls Gmail’s REST API to deliver mail.
  • No dependence on PHPMailer OAuth
    • Works even if the host’s PHPMailer is old or missing OAuth support.
  • Safe fallbacks
    • If Gmail isn’t connected, you can use a normal SMTP setup instead.
  • Thinkit Plugin Updater integration
    • Automatic update checks against Thinkit’s update server.
    • License-aware updates and potential rollback support handled centrally.

Perfect For

  • Agencies managing multiple client sites that need reliable WordPress email.
  • Site owners who want Gmail-based sending without learning Google Cloud in detail.
  • Anyone who wants a clear log of what WordPress tried to send and why something failed.
  • Developers who like simple, predictable behavior instead of “email might have gone somewhere… maybe.”
