Simple Basic Contact Form

I've looked high and wide for a simple contact form that is not bloated or slows down my website (Contact Form 7 is slow!). Even went with online form creators like Jotform and hated them. Luckily I stumbled upon this gem of a plugin. It's simple and doesn't slow down my site. I love the anti-spam feature too! I set a simple question that bots cannot answer and it stopped virtually all spam! No need for Recaptcha that adds bloat to my site. I can't recommend this plugin enough.

Perfect for my needs

This plugin adds a function called ‘esm_send’ that sends an email. Mail Server settings can easily be changed from the wp-admin interface.
The function works like so: esm_send($from, $to, $content, $subj = “”, $fromName = “”);
