Thank you for your call to the office yesterday regarding CASL compliancy, etc.
Our Tellem Email Marketing software is hosted on compliant Canadian-based servers (bonus for ALOT of government agencies and businesses). The double opt-in feature in Tellem will help you clean up your list.
To help you in your efforts to stay compliant with the new Canadian Anti Spam Law coming out July 1st, 2014, (details... www.fighspam.ca), check this quick help article that you can use to email to your customers. You'll need to have a newsletter signup form that can capture emails AND will send them an email. Tellem Email Marketing can handle this without any problems.
Hope that helps!
