Human error is a part of life but if we can avoid it, that’s ideal. With separate workspaces, I can keep our users’ information separate to avoid errors, and avoid having to send apology emails. Testimonial By Heloisa Assis

The onboarding experience at Customer.io was so great. Segment has the ‘replay’ feature, so it was super easy to switch over. Other companies claimed to have easy integrations with Segment but we found out the hard way that it wasn’t true. Testimonial By Neal O’Grady
