MailAI

Mailai Contact Form was built for founders and business owners who need a reliable way to receive leads without the bloat of traditional form builders. By allowing you to Bring Your Own SMTP, this plugin bypasses the often-unreliable native WordPress mail function and connects directly to your preferred provider (Amazon SES, Google Workspace, SendGrid, or private mail servers).
Built with a performance-first mindset, the form uses Modern Vanilla JavaScript (AJAX) to submit data without refreshing the page, providing a seamless experience for your users.
Key Features: 
* BYO SMTP: Total control over your email infrastructure. 
* Zero Bloat: No heavy CSS libraries or tracking scripts. 
* AJAX Submission: Fast, no-refresh form processing. 
* Security Focused: Uses WordPress Nonces and strict sanitization to protect your site. 
* SaaS Ready: Designed to work perfectly with modern business environments.
