what is the customer support email address?

Email is not one of the ways to contact customer support.

 

Phone support is not provided with the Free Edition.  If you are using a paid version of the software or if you purchased PLUS you can get phone support when customer support is there.  Otherwise, post your question here and someone will try to help.
