What does the software or service do well? ActiveCampaign does a very good job of utilizing marketing automation with its built in CRM. I have used Salesforce and other tools over the years and have felt that the email capabilites were always lacking... AC allows you to control both outreach and your crm using automations all built in the same system.
What does the software or service not do well? The functionality is powerful and something they could improve upon, is the interface... the core of the system has a lot of power, but using it can take a little getting used to. Just feels like it needs an update, nothing that should prevent anyone from using it tho.
What do you wish you had known about the software or service before using? I simply wish I knew about this product sooner. I wrestled with Salesforce for years and had I known this product was out there with automated email AND the CRM, I would have switched much sooner.
Have you used a competitor to the software or service? If so, how does it compare? I have used Saleforce for almost 6 years and did my best to customize it and create workflows so it actually helped my company sell, but it turned out to be a glorified spreadsheet lacking any kind of automated outreach tools based on deal status, etc. Active Campaign both handles outreach as well as automating your CRM (moving deals etc) which both help you complete tasks and makes more sales.
