The Article Counts determine how many articles you would like displayed in your newsletter. We will never display more articles than the maximum article count. The minimum article count is the minimum amount of articles needed for us to generate the newsletter. If there are not enough articles in the Upcoming page to meet the minimum number of articles, then the newsletter will not send to your contacts.
The max per source setting will determine how many articles per source display in your newsletter. For example, if max per source is set to 1 and you have 4 articles from Forbes in your Upcoming pool, each person will only receive 1 Forbes article. If your newsletter is at risk of not being able to generate because of this setting, it will be relaxed so that you don't fail to send.
You should receive an email from us letting you know that your newsletter needs more content to send if you are short on articles. Additionally if you are reviewing articles in Upcoming and toggle too many off, you should receive a pop-up alert letting you know that you're now under your minimum requirement to send. If you are not receiving these reminder emails or if you are ever unsure why your newsletter did not go out, contact us at firstname.lastname@example.org.
