Here are the instructions for setting up Sendible as a Destination.
Click the "Sendible" button under the Destinations tab, and type in a descriptive name. You’ll then see a URL for a RSS feed that you will copy and use in Sendible.
Log into Sendible, and click "Monitor," then "Feeds," then "New Feed":
Enter a feed name, then paste your ContentGems RSS Feed into the Feed URL box: Your ContentGems content is now integrated with Sendible as shown in the screenshot below. Enjoy!
