The SMTP plugin
you'll never replace.
Queue-powered. Background processed. Zero bloat.
The Problem
SMTP plugins
are broken.
Every SMTP plugin does the same thing — wrap WordPress's default mailing system with a fancy settings page.
They load heavy libraries. They block your page while sending. They timeout on bulk emails.
And somehow, they need 5MB+ just to send an email.
The Solution
We didn't wrap it.
We rebuilt it.
Insane Mailer queues every email and sends them in the background.
Your forms submit instantly. Your WooCommerce orders fly through. Your site stays fast — because email never blocks it.
