Bill C-28, how to deal with it?

The new bill C-28 affect us all. You will need to make adjustments in your lists.
You must know if the people to whom you are sending newsletter gave you their consent. There is 2 types of consent; implied consent and express consent.
Implied consent :
Express consent :
Sending an OPT-in email
We will be happy to send requests for consent to your current address emails. Just let us know which lists need to confirm their consent. We will create new lists that will automatically request for consent.
New lists
If you enter new addresses manually, consider the new law. Create a list of “Customer”, “Quote”, “Request”, “Public eMail”. Then you will use the custom fields and segments to date listings entries. As implied agreement has an expiration date, it is important to know when they gave you the agreement unless you have managed to get their express consent meanwhile.
Doubts
In case of doubt, if you cannot prove your relationship, send a request for consent. Remember to keep all your evidence; you may have to demonstrate those evidences.
