User Rating

13/15

An 86 out of 100 from 10 ratings is a positive signal but the sample size is small, so the score carries limited statistical weight.

Support Health

8/15

Support health is the weakest area, with zero support threads and zero resolutions tracked, leaving no public evidence of how the developer handles user issues.

What It Does

GoSMTP is a WordPress plugin that routes outgoing emails from your site through a third-party SMTP provider such as Gmail, Outlook, AWS, Zoho, SMTP.com, Brevo, or Mailgun, replacing the default PHP mail function. This improves email deliverability for transactional messages like order confirmations, password resets, and contact form submissions. It functions as a straightforward relay layer between WordPress and your chosen email service.

Who It's For

This plugin suits small to medium WordPress sites that need a reliable SMTP relay without the complexity of a full email-logging suite. It is a good fit for store owners, membership sites, and agencies that want quick setup with common providers like Gmail, Outlook, or Mailgun. Sites with very high email volume or strict deliverability requirements will likely need a more feature-rich alternative.

Who Should Skip It

If you need detailed email logging, open and click tracking, or backup SMTP routing, GoSMTP is too lightweight and you should consider Post SMTP or FluentSMTP instead. Site owners who already have a reliable transactional email setup with a custom API integration also do not need this plugin.

The Bottom Line

GoSMTP is a competent, actively maintained SMTP relay that earns an overall quality score of 85.92 out of 100 and should handle standard transactional email needs reliably. The lack of visible support activity and minimal feature set make it a better choice for simpler sites than for high-volume or compliance-heavy operations. For most users, WP Mail SMTP or FluentSMTP remain safer bets given their stronger communities and richer feature sets.
