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

A clean, secure, plug-&-play contact form for WordPress.

SMTP Mailer

So i have tried configuring it two ways - with gmail and smtp from my own hosting, it doesn't work in both cases.

With gmail it hangs on password authentication according to log - the password IS correct, less secure apps is checked and critical login is confirmed. 

With my own smtp credentials - it supposedly sending test message, but it simply doesn't comply with CF7, there's an error while sending form and that's it.

It is lightweight, which i really like but what of it if plugin doesn't work even on native settings?

To dev:
- if you fix it, then i will change my review. Latest WP, only your plugin and CF7, PHP 7.3 and default Wordpress theme.

It simply doesn't work with CF7

A bloat-free plugin that just sends SMTP emails as advertised. Great job Developers.

Minimalistic, Does the job


This is THE plugin you need to send e-mails. Forget about WPForms, Easy WP SMTP (after their upgrade it got super-bloated) or others. You just need to send e-mails, and this is the plugin to do it. Easy and lightweight.


The #1 SMTP plugin today


In the world of WP plugins, it's easy to get bogged down by bloated, feature-rich options. This plugin is a refreshing departure from that trend. It's lean, mean, and focused on doing one thing exceptionally well: sending emails.


Best SMTP plugin

Configure a SMTP server to send email from your WordPress site. Configure the wp_mail() function to use SMTP instead of the PHP mail() function.
