Technically there is no limit. It’s no problem with seven thousand, seven million, or even more.
I don’t think there are real-world needs to have such many contact forms, though.
Thank you very much for your prompt reply.
We use WordPress for a site that has thousands of stores and we want that when an email is sent through our site the store receives it directly and the person who sends it a copy of it.
We used Contact Form 7 for all our sites but we worried that it had some kind of limitation.

We have test sites we use check to our plugin, which extends CF7, which have over a thousand Contact Form 7 forms – works flawlessly.
We also display up 50 Contact Form 7 forms on a single page on these sites – takes 2-3 seconds to load which is fine for us.
You don’t need to create a contact form for each store. If you wisely use special mail-tags and/or default:* options, ideally one contact form will be able to cover all the stores.
