Does JotForm has a promotion at the moment?

Hi! I'd like to upgrade my plan to Silver. Do you have some offer for that plan? It looks like a couple of days ago it was $20 per month if paid yearly? And how can I transfer this account to my work email? I'm using my personal email now

I'm afraid we do not have currently a promotion, you may however, take advantage of the nonprofit or education discount, you may apply on the following links if possible:

About changing your account email address, you can do this on the settings page of your account, this is the direct link: https://www.jotform.com/myaccount/
