LethaldiranMX Insight
This utility addresses a critical architectural gap in WordPress email delivery by forcing MailPoet to route its transactional and newsletter traffic through the site’s active SMTP plugin rather than bypassing it. By standardizing the mail delivery pipeline, administrators can leverage existing SMTP configurations, OAuth-based connections like Gmail or Outlook, and centralized email logging without paying for MailPoet’s proprietary sending service or setting up redundant API integrations. It effectively unifies a site’s email infrastructure, ensuring that deliverability optimizations applied globally to WordPress also protect high-volume newsletter campaigns.
Best Fit & Operational Role: This plugin is an ideal fit for agency developers and site administrators who manage newsletter campaigns via MailPoet but prefer to centralize their deliverability stack under a single SMTP provider, such as FluentSMTP, WP Mail SMTP, or Post SMTP. It solves the operational headache of fragmented email routing, allowing teams to utilize cost-effective or highly secure SMTP relays (including Gmail/Google Workspace via OAuth) that MailPoet does not natively support. By routing all traffic through the main SMTP plugin, it also enables comprehensive delivery logging and debugging within a single dashboard, simplifying long-term site maintenance.
Potential Limitations & Pitfalls: Because this plugin acts as a bridge between two distinct systems, major core updates to MailPoet may introduce compatibility issues that require manual adjustments or plugin updates. Additionally, routing newsletters through an external SMTP plugin can alter or disable advanced native MailPoet features, such as automated bounce handling, which may require alternative monitoring strategies. Thorough testing with both test emails and live campaigns is highly recommended during initial deployment to verify that high-volume queues do not overwhelm the active SMTP relay.
The missing link between MailPoet and your SMTP plugin – for reliable email delivery!
By default, MailPoet sends emails via PHP Mail, its premium MailPoet Sending Service, or services like Amazon SES or SendGrid. But there’s a catch: Some SMTP providers (like Gmail) aren’t supported, and email logging isn’t possible.
➡ This plugin fixes that. It ensures all MailPoet newsletters are sent via your chosen SMTP plugin, so your WordPress email settings apply to newsletters, too – without extra setup or extra costs.
🛠 Works with popular SMTP plugins like:
✅ WP Mail SMTP (by WPForms – the most widely used SMTP plugin)
✅ FluentSMTP (lightweight, free, GDPR-friendly)
✅ Post SMTP (supports OAuth for Gmail, Outlook, etc.)
✅ Easy WP SMTP (simple & reliable)
✅ MailerSend, Brevo (formerly Sendinblue), and more
🎯 Why use this plugin?
✔ Ensures MailPoet emails follow your SMTP settings
✔ Works with Gmail & other SMTP providers MailPoet doesn’t support
✔ Enables email logging via your SMTP plugin
⚠ Important notes:
- Major MailPoet updates may require adjustments.
- Some advanced MailPoet features (like bounce handling) may behave differently.
✅ Test your setup with MailPoet test emails and real newsletters to ensure everything runs smoothly!
