Essential Form – The lightest plugin for contact forms, ultra lightweight and no spam
Looking for a no-fuss, ultra-lightweight contact form that just works? Essential Form gives you exactly what you need — no more, no less. Use the shortcode [essential_form] wherever you want a simple contact form with the following fields: Name Email Message Agreement checkbox That’s it. No extra fluff, no performance hit. ⚡ Zero Bloat. Zero Requests. Zero Spam. Essential Form adds no HTTP requests, loads no external libraries, and runs on pure Vanilla JavaScript — only 1 kB of inline script, injected only on pages with a form. When we say it’s the lightest contact form ever made, we mean it. The entire plugin zip is just 14 kB. 🛡️ Anti-Spam, Reinvented (No Captchas, Ever) Our invisible anti-spam system blocks all automated bots — no annoying captchas, no puzzles, no headaches. Here’s how it works: Each form submission uses a unique, random token 20 random security keys are generated per site AJAX actions have unpredictable names like essential_form_fbe52b696 Robots can’t guess or simulate a valid submission The result? Only real humans get through. Bots don’t stand a chance. 🧘♀️ Keep It Simple Most of the time, all you need is a name, email, message, and a simple checkbox. That’s exactly what Essential Form gives you. If you need complex forms with extra fields or logic, this plugin isn’t for you — try Contact Form 7 instead. But if you want something fast, clean, and incredibly secure, Essential Form is for you. Try Essential Form today — and enjoy a faster, cleaner contact form experience. How to add a contact form on the page Add the shortcode [essential_form] Done! Features of the Contact Form Extremely lightweight – The plugin inlines about 1 kB of pure Vanilla JavaScript (even smaller when compressed) only on the page where you use the shortcode — and never above the fold. On all other pages, it doesn’t exist at all. You could say it only “exists” on a page because the form is visible — otherwise, you’d never know the plugin is there. No tool will be able to measure any meaningful resource usage caused by this plugin. The contact form includes only four fields: name, email, message, and an agreement checkbox. Nothing else. If you need more fields, this plugin isn’t for you. But if that’s all you need — you’ll love how simple and fast it is. It inherits your theme’s styles automatically. If you want custom styling, you can add your own CSS — or use a different plugin if you need more built-in design options. It includes a powerful, invisible anti-spam system. Bots won’t be able to send messages through your form. Only real humans can submit it — and if you ever get spam, it will be from a human doing it manually. No captchas, no puzzles, no user frustration. The anti-spam system works entirely behind the scenes — quietly and effectively. Shortcode Parameters You can customize the form labels and messages using these shortcode parameters: label_email label_message button_text agreement_text success_message Example usage: [essential_form label_email="Your email" label_message="Your message" button_text="Send" agreement_text="You agree with our privacy policy" success_message="Thank you for your message!"] If you don’t provide these parameters, the plugin will use the default values. How to customize the contact forms You can also customize the contact forms throught the filter hook ‘essential_form_settings’. Here an example. add_filter( 'essential_form_settings',function( $options ){ return array_merge( $options, array( 'email_from' => '
[email protected]', 'email_to' => '
[email protected]', 'email_subject' => sprintf( esc_html__( 'Message from %s','your-domain' ),get_bloginfo( 'name' ) ), 'label_name' => __( 'Name','your-domain' ), 'label_email' => __( 'Email','your-domain' ), 'label_message' => __( 'Message','your-domain' ), 'button_text' => __( 'Send','your-domain' ), 'agreement_text' => __( 'By submitting this form I agree with the privacy policy','your-domain' ), 'success_message' => __( 'Form submitted successfully! Thank you for your message!','your-domain' ), 'name_missing_error' => __( 'Name is a required field!','your-domain' ), 'email_missing_error' => __( 'Email is a required field!','your-domain' ), 'email_not_valid_error' => __( 'Email not valid!','your-domain' ), 'message_missing_error' => __( 'Message is a required field!','your-domain' ), 'message_too_long_error' => __( 'This message is too long! Please, write not more than 50000 characters.','your-domain' ), 'missing_agreement_error' => __( 'You have to agree with our privacy policy to submit the form.','your-domain' ) ) ); } ); If you need to do a custom action after the sending of the email, you can use the action hook ‘essential_form_after_sending’. Here an example. add_action( 'essential_form_after_sending',function( $name,$email,$message,$post_id ){ //$name is the name of the user who submitted the contant form //$message is the message which is sent through the contact form //$post_id is the ID of the page where is included the contact form //Your code here },10,4 ); If you need to customize the message that is included in the email, use the filter hook ‘essential_form_message’. Here you have an example. add_filter('essential_form_message',function( $message,$name,$email,$post_id ){ if( isset( $_SERVER['REMOTE_ADDR'] ) ){ $message .= ' IP: '.sanitize_text_field( $_SERVER['REMOTE_ADDR'] ).' '; } return $message; },10,4 ); If you need to customize the agreement text, use the filter hook ‘essential_form_agreement_text’. Here you have an example. add_filter( 'essential_form_agreement_text',function( $text ){ return 'By submitting this form I agree with the Privacy Policy '; } ); Limitations The limits of Essential Form are many, but they are what make this plugin the best if you need a ultra-lightweight contact form with just name, email, comment, and privacy agreement. If you need more, you can always install more complete but also heavier contact forms like: Contact Form 7 WPForms Forminator Formidable Forms Ninja Forms and many other amazing plugins for contact forms. How to speed up the form submission and avoid conflicts with other plugins Install and activate Freesoul Deactivate Plugins Go to Freesoul Deactivate Plugins => Plugin Manger => Actions => Essential Form Deactivate all the plugins for the actions “Getting secret key during submission” and “Form submission” By using Freesoul Deactivate Plugins to clean up all the other plugins, the form submission will be faster and without any conflict with third plugins. Demo You can see Essential Form in action on my blog post The Lightest Contact Form Plugin Ever You don’t need any demo for the backend, because there are no settings for this plugin. Just use the shortcode [essential_form] where you want to add the form, and customized as mentioned in the description. I need this plugin to do something custom If you want to integrate this plugin with other tools or workflows, I offer a custom development service for WordPress plugin integrations and feature extensions.

SMTP configuration with proper authentication for your WordPress site ensures that your WordPress emails do not end up in spam. By default, WordPress sends emails using the PHP mail function, which isn’t ideal because most WordPress hosting servers don’t support PHP email. On top of that, most email clients, such as Outlook (Office 365 / Microsoft365), Yahoo, Gmail, Brevo, Zoho, Amazon SES, Mailgun, etc., automatically block or mark spam emails that lack proper authentication.

How Does Post SMTP Work?
