Thank you for coming to the community with your question! When you first try to send an email, many people overlook the physical address information at the bottom of the page. Since that information is required by several national and international laws, we do require you to fill that out before your first send. A full walkthrough of the sending process can be found here.
I have been doing emails for yours - I got that. But I was trying to use the share email feature for the first time...and it was not easy. I am not sure I actually did it, or if it is how I would like it to be seen, or whether it completely failed - I have no idea. The sequence of going through start to finish was not clear or friendly.
I'm sorry about misunderstanding at first. I took a look at your account, and I do see that your most recent campaign has two posts scheduled to your Facebook page, though it looks like they might have gotten scheduled for the exact same time. I would suggest editing those before they go out. From your campaigns page, click the name of your scheduled email, then scroll down to the 'Social Promotions' section and click 'Manage Posts'. Then you'll see two text blocks, with an image to the right of them, and a time listed below them. Modify the one you want to use, choose the picture on the right, and then click 'Remove Post' on the one you no longer need. Just click the yellow 'Save Changes' button at the top of the page when you're done.
