A drip campaign is a series of emails sent automatically over time to guide someone toward taking action, like making a purchase or booking a call. Mailchimp, ActiveCampaign, and ConvertKit are popular tools for this. ActiveCampaign is known for being powerful with automation logic, which means you can set rules like "if someone clicks this link, send them this email next." ConvertKit is simpler and works well for creators and small businesses. What do you think is the most important feature to look for in a drip email tool?
