Three features, useful at the right moment
The core plugin is free and will stay free. Buy the Pro add-on only when you actually need it.
File upload
Add a file upload field to any form. Clients send documents, quotes, or photos directly with their enquiry. Uploaded files arrive as attachments in the notification email.
Supported formats: PDF, images, documents, ZIP · configurable max size
Custom thank-you page
After submission, redirect the visitor to any URL. Create a targeted thank-you page where you continue selling, offer an upsell, or simply confirm receipt of the enquiry.
Great for: funnel sites, e-commerce enquiry forms, lead-gen pages
Premium templates
Send notification and confirmation emails with your logo, brand colours, and a clean HTML design. The customer receives a professional-looking message instead of the default WordPress email.
Configured in: Mailfix → Settings → Email template · live preview

What web designers and site owners say
"I'd been looking for file upload in a form for a long time. Other plugins either don't offer it for free or the setup is complicated. With Mailfix Pro it worked within two minutes."
"I build custom sites for clients and everyone wants different email templates. With the Pro add-on I configure it in no time and the result looks professional."
"€42 a year is a fair price. The custom thank-you page helped me with conversions in my e-shop with an enquiry form. It paid for itself in the first month."
