We value your unique insight into our products and services and often receive ideas and feedback from our community in a variety of ways. To streamline this process, we’ve created an idea bank where you can post product suggestions, vote for those most important to you, and add comments to existing ideas.
We use Solicit Codes for this. Make a code that something like "Do not send membership renewal". You can block Solicit Codes from getting renewals by going to the renewal template and choosing the Contact tab. You can add solicit codes here. I hope that helps. :)
