Slack - Onboarding Email Sequence
Slack is a cloud-based communication- and collaboration tool. They make it easier for teams to work together and are wildly popular amongst businesses around the world.
In this onboarding process, Slack brings new subscribers through a series of onboarding steps in their browser, followed by a series of emails. Normally, if you were to leave all settings as they are and you actively use Slack for communication with your team, they will also send you emails about the messages you have received inside slack etc. Unfortunately these are not visible inside this sequence, but please keep in mind that they are actually part of the onboarding emails.
