Description

Link SMTP Pro is the paid upgrade to the free Link SMTP plugin. It fixes unreliable WordPress and WooCommerce email by sending through your own Google (Gmail API), Microsoft 365 (Graph), or SMTP mailbox using a secure one-click OAuth connection — no app passwords, no fiddly host/port setup. Pro removes the free plan’s 300-emails-per-month fair-use cap and unlocks multiple connected accounts, a full email log with deliverability analytics (success rate, daily volume, per-provider breakdown), and scheduled sending with automatic retry. Your email always sends from your own mailbox, so delivery stays private and is never billed by Quality Lead Gen. One-time payment, one site, lifetime updates. Buyers receive a pre-stamped download that activates automatically on install, with manual key entry available as a fallback. Setup, OAuth configuration, the scheduling API, and troubleshooting are documented at https://qualityleadgen.ca/link-smtp/docs/ (see the Getting Started, Connecting Google & Office 365, Scheduling API, and Troubleshooting subpages).
