Outplay is very easy and useful automation tool to reach the customer for sending bulk emails at one time.

look of alternates, they are cheaper and gets your job done

Outplay is simple to implement and powerful enough to let you automate tons of outbound processes...SMS, email, dials - when I was using this, I was able to closely replicate automations I had running in HubSpot, which is pretty impressive. We used this every day, easily integrated it with our processes and their customer support was always top notch.
