SwiftTrap for Mailtrap

SwiftTrap for Mailtrap replaces the default WordPress wp_mail() with the Mailtrap Send API.

Features:

• Send transactional and bulk emails via Mailtrap
• Automatic email categorization (welcome, password-reset, notification, etc.)
• Bulk stream routing for promotional emails
• Email logging with retention management
• Dashboard widget with account stats
• Test email from settings page

No SDK required — uses the WordPress HTTP API (wp_remote_post) for zero external dependencies.

Extensible via filters:

• swifttrap_mailtrap_email_category — override email category
• swifttrap_mailtrap_use_bulk_stream — control bulk stream routing
• swifttrap_mailtrap_template — send via Mailtrap template (template_uuid)
• swifttrap_mailtrap_custom_variables — attach tracking metadata to emails
