Great plugin. Simple to use. Works Great.
I have tried all of the big name contact forms (ninja, contact form 7, wp forms), and I always come back to the Clean and Simple Contact Form.
It is as simple as you can get, and does everything you need.
I really appreciate the email verification option, which you don’t always see on these other forms, but will always want because if you don’t know the persons email, you can never contact them back.
Thanks so much for all you do!
initially it is working but sometimes it is not working, presently Im facing the same problem, i request creators to fix the bug
Super. I’ve been using it for years and it works flawlessly.
Set it and forget it. Lovely!
