Complete Mailer Guide

How do Post SMTP mailers handle issues with email delivery?

Post SMTP mailers are crucial in resolving email delivery issues, ensuring your messages reach their intended recipients reliably. Unlike traditional email methods, Post SMTP employs a specialized approach to handle outbound mail. Utilizing secure and authenticated protocols minimizes the chances of emails being flagged as spam or encountering delivery hiccups. 

This plugin fine-tunes the technical aspects of your email configuration and offers detailed logs and alerts to help diagnose and rectify any potential problems. 

Configuring a mailer helps you to send emails from your WordPress site more reliably and securely. Some servers may have issues with the default WordPress mailing function, which can cause your emails to fail or go to spam. A mailer can avoid these issues and ensure your emails reach their destination.

Post SMTP offers different mailers that you can choose from, depending on your site’s needs and preferences. Each mailer has its own advantages and requirements. Below is a brief overview of each mailer in Post SMTP.

Gmail API:

You can improve your email deliverability capabilities by utilizing the strength of Gmail’s infrastructure and features by integrating the Gmail API into the Post SMTP plugin. 

This integration allows you to manage your Gmail accounts, send emails, and access valuable email-related data directly from your WordPress environment. 

This configuration opens up a world of possibilities for improving email communications, automating tasks, and gaining insights into email performance.
