Don't worry, Certify'em will remain a free tool with all the same features it's had until now! The only small change will be an attribution label added to each certificate sent. The attribution will say
"Made for free with Certify'em", and will appear in the bottom-right of each certificate. The image below shows approximately how this will look.
This attribution label will be added starting October 26, 2020. If you you plan to continue using the free version of Certify'em, you will need to update your certificate template(s) to accommodate this change before then.
