2. Go to the section 'Opt-ins'.
   
   
3. Click to the right of the channel you wish to change. Or if you wish to remove the channel, click  to the right.
   
   
4. Replace the channel (e.g. the Email address field) with the new channel. Ensure there are no spaces. 
   
   
   
5. Click 'Update'
   
   
6. 'save' the contact.
