Excellent with great free version to start you off

I use Divi from Elegant Themes. But their forms are a bit limited e.g. you can’t send a confirmation email after ‘submit’. WPForms answered the call and enabled me to create a simple contact form and appointment form and integrate it into Divi – all in a pretty quick time. I managed with the free one to get the form up and running and to send a confirmation email to the customer as well as one to ourselves. I’m pretty sure I’ll get round to upgrading to the paid version at some point (I think if it was a bit cheaper I’d have done that already, I just need to justify the cost to myself). So for now, the free one has done pretty much everything we needed. Thank you!
