A message from the developer
For more than 15 years, I have worked with WordPress websites and plugins, and for over 10 years I have focused on email deliverability. My work has covered e-commerce, email servers, email marketing, and automation flows—areas where dependable email is essential to daily operations.
I have operated private email infrastructure that handled up to 30 million emails a day. That experience taught me that email delivery is more than sending a message: it depends on careful configuration, trustworthy systems, and attention to the details that help critical emails reach their intended recipients.
I built BooleanSMTP as one way to share that practical knowledge with the WordPress community. My goal is to help you create a more reliable email experience for your customers, team, and business, and to keep improving the plugin in ways that make dependable delivery easier to achieve.
How we build it
- Free means complete. The free plugin has no limit on connections and no licence check.
- Say exactly what it does. Every claim on this site is generated from, or checked against, the plugin’s own code.
- Your data stays yours. Logs live in your database, credentials are encrypted, and nothing is collected.
