Flexa MailBridge

Flexa MailBridge is the email delivery layer for your WordPress site. It sits between wp_mail() and your mail provider, so every message your site sends (order emails, password resets, form notifications, newsletters) goes out through a real mailer instead of the default mail() that so often lands in spam. Around that core it adds the parts a dependable delivery pipeline needs: a fallback mailer for when the primary one fails, an optional background queue that retries temporary failures, a full log of everything sent, open and click tracking, and delivery reports. Routing and fallback Set the From name and address (with optional force overrides), pick a primary mailer, and choose a fallback that takes over automatically if the primary fails. Eighteen transports are supported:

• Custom SMTP (any host)
• SendGrid, Mailgun, Brevo (Sendinblue), Postmark, Mailjet, SparkPost, SMTP.com, SendPulse, Pepipost, Mandrill, Amazon SES, Yournotify
• IONOS
• Gmail / Google Workspace, Outlook / Microsoft 365, and Zoho Mail (OAuth: connect with a click, no password stored)
• WordPress default (mail())

API credentials and OAuth tokens are encrypted at rest (AES-256-GCM) and are never returned to the browser in plain text. Delivery queue and retries Turn on the optional queue to send email in the background instead of during the page request, so a slow provider never holds up checkout or a form submission. Temporary failures (rate limits, timeouts, transient provider errors) are retried with backoff up to a limit you set; permanent errors are left alone rather than retried forever. The queue is off by default, so nothing changes until you enable it. Email logs Every message is logged with its status (sent / failed / pending), mailer, recipients, subject, source, and the exact error when a send fails. Browse, search, and filter the log, open any entry to see its full body and engagement, and export the current view to CSV. Set a retention window to prune old logs automatically. Open and click tracking Optionally embed a tracking pixel and rewrite links so you can see which emails were opened and which links were clicked, per message. Reports A dashboard widget and a Reports tab summarise delivery trends (sent vs. failed, open and click rates, busiest mailers, top links) over 7/30/90 days, with optional weekly and monthly digest emails. WP-CLI

• wp flexa-mailbridge log list: list and filter the email log (status, mailer, search, date range; table/csv/json output)
• wp flexa-mailbridge log get <id>: show one entry in full
• wp flexa-mailbridge test <to>: send a test email through the active mailer
• wp flexa-mailbridge reset: wipe all Flexa MailBridge data

Import Migrate settings and logs from WP Mail SMTP, Easy WP SMTP, SMTP Mailer, WP SMTP, or WP Mail Bank. Secrets are re-encrypted on import.

1.0.1

• New: an optional deactivation feedback survey. If you deactivate the plugin, a short survey asks why, so we know what to improve. It is entirely optional, admin-only, and never blocks or delays deactivation. See the External services section for exactly what is sent and how to turn it off.

1.0.0

• First stable release.
• 18 mailers: custom SMTP, 13 API providers, 3 OAuth providers (Gmail/Outlook/Zoho), IONOS, and WordPress default, with a configurable fallback mailer.
• Optional background delivery queue with automatic retry of temporary failures.
• Email logging with search/filter, per-message detail, CSV export, and automatic retention.
• Open and click tracking.
• Delivery reports (dashboard widget, Reports tab, weekly/monthly digests).
• Import of settings and logs from five other SMTP plugins.
• WP-CLI: log list, log get, test, reset.
• All secrets encrypted at rest (AES-256-GCM); OAuth and tracking endpoints use HMAC-signed tokens.
