How do RSS campaigns work?
When you create a new RSS campaign, it is not immediately filled with content from the feed. The feed is checked and processed when the scheduled time for sending a campaign comes.
You can check or uncheck Show only the new posts checkbox in RSS Settings, which affects how the feed is populated.
When unchecked, the campaign will be fully populated with most recent posts every time, regardless of their publish date.
When checked, the campaign will be populated only with posts published since the campaign was setup OR sent last time. This is helpful when you don’t want to flood your subscribers with older posts. Every post will be sent only once.
Please note that updated posts will not be sent as new ones.
