ActiveCampaign is our email tool of choice.

Way beyond bulk email campaigns, ActiveCampaign is the engine behind the follow-up that creates the majority of sales for us and our clients.

The system has the ability to send out perfectly tailored emails in response to almost any action your prospects might take, and has the best set of integrations with our other tools I've ever seen.

More demanding users have the option of adding a sales CRM, and even recording ecommerce transactions for each user.
