Our cold email process used to be messy. Responses were forwarded around and often hard to track. With MasterInbox, we have completely streamlined it. The Slack integration has also been a huge win, giving us instant lead notifications and improving our reporting.

Running outbound campaigns on LinkedIn and email was a huge pain, and the LinkedIn inbox itself is too unreliable for keeping track of conversations. Master Inbox allows us to bring replies together and be much more nimble as an agency. We've basically onboarded more clients!
