You can filter automations by confirmation date and engagement

Automations just keep getting cooler and more powerful! We've added support for "number of opens", "number of clicks", and "date joined" as filters for your automations. Here are some automations that are now possible:

• "If someone has opened five emails in the past month but hasn't upgraded to a paid plan, send them a discount code for 20% off."
• "If someone hasn't clicked on any links in the past two months, send them a survey asking for feedback."
• "If someone who joined my list more than a year ago upgrades to a paid plan, send them a special thank you note."

Check out the full automations reference here for the full dossier of triggers, filters, and actions.
