SwiftTrap for Mailtrap

Mô tả

SwiftTrap is a drop-in replacement for wp_mail() that routes WordPress email through the Mailtrap Email Sending API instead of SMTP. It is purpose-built for Mailtrap — not a generic SMTP plugin with a Mailtrap preset — so it exposes Mailtrap-native features that SMTP cannot: bulk vs transactional stream routing, email categories, custom variables for tracking, suppression lists, and domain verification status.

Why HTTP API instead of SMTP?

• Lower latency — one HTTPS call per message, no MAIL FROM / RCPT TO / DATA round-trips.
• Better deliverability — Mailtrap routes API messages through its dedicated transactional and bulk streams; SMTP doesn’t expose stream selection.
• Native categories — every email is automatically categorized (welcome, password-reset, notification, marketing, etc.) so you can filter and report on them in Mailtrap.
• No firewall headaches — port 587/465 blocked? API works over standard HTTPS 443.

Why SwiftTrap and not WP Mail SMTP / Post SMTP

• Generic SMTP plugins use Mailtrap’s SMTP credentials and lose every Mailtrap-only feature.
• SwiftTrap calls send.api.mailtrap.io for transactional mail and bulk.api.mailtrap.io for bulk mail — automatically, based on category or via filter.
• No Mailtrap PHP SDK required. Plugin is ~30 KB total and uses only the WordPress HTTP API (wp_remote_post).
• Stats page shows your sending domain verification status and the live suppression list (bounces, complaints, unsubscribes).

Features

• Drop-in replacement for wp_mail() — works with Contact Form 7, WooCommerce, Gravity Forms, and any plugin that uses WordPress mail.

• Email log with retention management — see what was sent, when, and to whom.
• Dashboard widget — at-a-glance integration status and quick links to Stats and Settings.
• Stats page: sending domain verification status + suppression list.
• Test email button on the settings page.
• Mailtrap template support via template_uuid.
• Falls back to default WordPress mail handler when disabled or token is empty.

Privacy

This plugin sends email payloads (recipients, subject, body, attachments) to the Mailtrap API at send.api.mailtrap.io and bulk.api.mailtrap.io. Account stats are fetched from mailtrap.io/api/accounts. See the Mailtrap Privacy Policy. No data is sent anywhere else.
