As it stands we do not have an official best practice for trying to market with Pinterest; however, I believe that you are able to post links with your posts. This may be a good location to include a short URL to your campaigns or a sign-up form for people to join your list to receive future updates. I hope this helps with giving you some ideas!
Please let us know if there is anything else we can do for you.
