Reviews
what people actually sayPost SMTP is a well-regarded and long-trusted email deliverability plugin for WordPress with genuinely responsive support, but it carries persistent complaints about unsolicited admin UI injections, aggressive marketing practices, and questionable data handling that undermine its otherwise solid reputation.
What people like
- +Reliable email delivery that works where other SMTP plugins fail×3
- +Useful email logging feature for troubleshooting and resending messages×2
- +Easy setup and configuration×3
- +Fast and helpful support from the team, including for free-tier users×5
- +Trusted and used reliably across multiple sites over many years×3
- +Secure Google API integration available in the free version
Common complaints
- −Plugin automatically scrapes the admin email address and sends unsolicited emails and newsletters without explicit opt-in, which reviewers flag as a GDPR violation
- −Injects unsolicited menu items and popup banners into the WP admin dashboard; 'don't show again' option reportedly does not work×2
- −Dishonest or unclear pricing — free tier has limitations and Microsoft 365 users face a mandatory paid upgrade
- −Unusually large plugin file size (~20MB zipped) compared to alternatives
- −Pro version required for certain features, which some users find to be an upsell on functionality they expect to be free
