You can set either a $0 amount price or use a 100% coupon/discount

No actual payments will be attempted for 0 balance due invoices

(or anything below the minimum charge amount for your currency)

So the 0.00/year attempt is ok?

How's the 100% coupon/discount will work?

I simply have 3 plans: Free, silver (50 eur / year), gold (100 eur / year). I've found it most convenient way to do so... For my app

100% coupon/discount is for the plan that will cost something right? I need a plan that won't cost anything to exist...

Actually, one more question: does stripe send emails when subscription is renewed to customer? And what if the subscription is free, like in my case? Will the email be send also in this case?

Yes, you can 100% discount a subscription using a price for any amount, if you want

Or you can use a $0 price, its up to you, depends what you want the customer to see on the invoice

YOu should test both, look at the invoice, and decide what you want

If you enable payment receipts and payments are made, yes those are sent automatically

If there is no payment and the subscription is for $0 and set to charge_automatically then no i wouldn't expect any automatic emails
