M4W SMTP Mail Scheduler is a WordPress plugin that allows you to queue and send emails using custom SMTP profiles. It intercepts wp_mail calls, stores emails in a database, and sends them asynchronously via a cron job, ensuring reliable email delivery with configurable SMTP settings.

Features

  • Email Queuing: Replaces wp_mail to queue emails for scheduled sending.
  • SMTP Profiles: Configure multiple SMTP profiles with settings like host, port, and authentication.
  • Profile Snapshots: Stores a snapshot of SMTP settings for each email to prevent issues from profile changes or deletions.
  • Priority and Scheduling: Assign priorities to emails and schedule them for specific times.
  • Admin Log Interface: View queued, sent, and failed emails with details like recipient, subject, profile, and status.
  • Retry Mechanism: Automatically retries failed emails up to a configurable limit.
  • Clean Logging: Limits the number of stored email logs to prevent database bloat.
  • Scheduler Toggle: Enable or disable the email scheduler. When disabled, emails are sent immediately.
  • Email Filters: Create rules to filter emails based on subject, body, or recipient patterns. Actions include bypass scheduling, do not send, or set custom priority.

Installation

  1. Download the Plugin:

    • Clone the repository or download the ZIP file:
      git clone https://github.com/your-username/smtp-mail-scheduler.git
    • Or upload the plugin folder to wp-content/plugins/smtp-mail-scheduler/.

  2. Activate the Plugin:

    • In the WordPress admin dashboard, go to Plugins > Installed Plugins.
    • Find SMTP Mail Scheduler and click Activate.

  3. Configure SMTP Profiles:

    • Navigate to the plugin’s settings page in the WordPress admin (e.g., Settings > SMTP Mail Scheduler).
    • Add one or more SMTP profiles with details like host, port, username, password, and encryption.
    • Set an active profile for sending emails.

Usage

  1. Queue Emails:

    • Use WordPress’s wp_mail function as usual. The plugin will intercept and queue emails using the active SMTP profile.
    • Example:
      wp_mail('recipient@example.com', 'Test Subject', 'Test Message');

  2. View Email Logs:

    • Go to the plugin’s log page in the WordPress admin to view queued, processing, sent, or failed emails.
    • Use actions to retry failed emails, remove emails, or prioritize queued emails.

  3. Manage SMTP Profiles:

    • Add, edit, or delete SMTP profiles in the plugin settings.
    • Each queued email stores a snapshot of the profile settings to ensure consistent sending even if profiles change.

Requirements

  • WordPress 5.0 or higher
  • PHP 7.4 or higher
  • MySQL 5.7 or higher (for JSON support in profile_settings)
