Zapier is an integrations tool that lets you connect many hundreds of cloud apps and other services to share data across tools or trigger actions between one tool and another. The workflow for building zaps is simple. You choose a trigger, like receiving an email in Gmail, then choose an action, like recording a Segment event for each email you receive. Zapier also has a filter capability, so you can choose to only record when emails are received from specific people or sent to a specific email address. This is just an example, and there are limitless use cases for Zapier if you’ve got the time to build connections between each app.
