we run a course company and are currently reform our record system.

i want to add our products to our contacts but not sure how to do it efficiently, and adding products one by one to contacts manually will take too long. 

Is it possible to add a product to several contacts at once?

The scenario is we have an excel or csv file with all of the contacts details for a specific product. with name, email, etc.

Thank You!
