We use ActiveCampaign for our wedding venue for pre-sale marketing and post-sale operations. It's been extremely beneficial for us. We have many automations that are easy to build out with their interface and integrate with the software we use (Zapier, Salesmessage, and Calendly). The "Deals" section makes it easy to track our pipeline and add notes and info to leads. It's always been very reliable - I don't think there's ever been downtime in the past 1.5 years we've been using it.
