Canada Anti-Spam; Sending out notices to get permission from your contacts is necessary today. The laws in Canada have changed. Providing them with an easy ‘Say Yes’ clickable button is great. Having them sign up for your newsletter as the only option while requesting permission, not so great.
If you have an e-mail contact outside of your e-mail newsletter subscriber list, don’t offer them as the only way to say yes is by subscribing to your newsletter. Offer them the choice to ‘stay in touch’ as well. I just turned down a request to e-mail because that was the only option in the request. I wasn’t even on their newsletter list to begin with and now the only way I can stay in touch is to subscribe to your newsletter. No thanks.
