Thanks for posting about this, I didn't realise Jotform was cheaper than Wufoo. I prefer creating form submissions in this way because I've had problems in the past with html form submissions like Gravity Forms on Wordpress. Email deliverability can be a problem -sometimes emails are never delivered because of spam filters.
The only problem I find with Wufoo is that there can be a slight delay to load the form when the page loads. Does anyone have tips for speeding it up?
