GoSMTP – SMTP for WordPress

What is GoSMTP?

GoSMTP is a WordPress plugin that replaces the default PHP mail function with SMTP or API-based email sending. Developed by Softaculous, it has been available for 3 years and currently has over 500,000 active installs. The plugin holds a 4.3 out of 5 star rating from 10 reviews, with 80% of users awarding five stars. Its primary goal is to improve email deliverability by bypassing restrictive hosting server configurations.

Many hosting providers impose strict limits on the PHP mail function, which can cause emails to land in spam folders. GoSMTP connects your WordPress site directly to third-party email services like Sendgrid, Mailgun, or Gmail SMTP. This direct connection ensures transactional emails, password resets, and notifications reach user inboxes reliably. The plugin supports 17 different email providers, including custom SMTP configurations.

Who Should Use GoSMTP?

GoSMTP is designed for site owners who experience email delivery failures or spam placement due to shared hosting restrictions. The plugin suits beginners, as setup requires only selecting a provider and entering API credentials. It is equally useful for developers managing multiple client sites, given the 500,000+ install base indicates broad compatibility. Sites that send user registration emails, order confirmations, or password resets benefit most from its direct SMTP connections.

Small businesses and e-commerce stores running on budget hosting are the primary audience. The free tier covers 14 mailers, which is sufficient for most traffic levels. Administrators who need to audit sent emails or resend failed messages will find the logging feature essential. The plugin also appeals to agencies that require smart routing to separate transactional alerts from marketing campaigns.
