Effortless Email Management: Integrating Post SMTP with MainWP for Multiple-Site Control

If you’ve used WordPress, you’re likely familiar with its built-in email function, wp_mail. However, if you’ve managed multiple WordPress sites, you’re probably familiar with the fact that the wp_mail function is not reliable for sending emails.

Fortunately, you can easily counter this issue by installing a WordPress SMTP plugin such as Post SMTP that lets you connect with all major third-party email service providers (like Gmail, Microsoft 365, Amazon SES, Sendgrid, etc.) for reliable email delivery.

The benefits of using SMTP services to send email include: 

• Scalability & Reliability: Outsourcing email handling keeps your web server’s load minimal, which allows it to handle web requests more efficiently.
• Improved Deliverability: Third-party email services come with dedicated infrastructure and authentication protocols like SPF, DKIM, and DMARC to boost email deliverability.
• Efficient Email Queue Management: These services can manage large email volumes more effectively, ensuring timely dispatch without overloading your server.
• Compliance and Security: They’re often better equipped to comply with international regulations, which reduces your legal liability.

Using a Third-Party SMTP Plugin

Configuring your WordPress to use a third-party SMTP server is simplified with SMTP plugins. Many are available for free in the WordPress Repository. However, they can be cumbersome to configure, especially across multiple sites.
