Error!

I found company's contact information online. Can I send them a cold message, if what I'm selling is actually relevant to them?
SHORT ANSWER: You can, if you their contact information is publicly avalable, and there are no statements that they don't want to be contacted.
A customer called me a week ago and asked a question about my product. Today I sent them a follow-up message and asked if they were still interested. Did I violate CASL?
SHORT ANSWER: You did not, if you recorded their call
