When your content gets a lot of engagements or even goes viral, you can take the opportunity to automatically add a reply with a link or follow-up. This will catch the attention of everyone who is engaging with the tweet, and also bump it again in people’s timelines.
To set this up, just click on the auto-plug toggle to write the follow-up tweet beforehand, and choose the engagement threshold that, when hit, will attach the tweet to your content.
