Buying through a partner
What is a Master Inbox partner?
An outbound agency that sets up and runs Master Inbox for the sales teams it works with. Partners are trained by our team and support every customer they bring.
Who do we pay?
You buy Master Inbox from us on the same plans as any sales team, and you own the workspace and the data. What the partner charges for its own services is between you and the partner.
Can we start without a partner?
Yes. Most sales teams buy directly and start with a free 7-day POC on their own inboxes. A partner is for teams that want someone to run it with them.
Rather run it yourselves? See the plans and start your free 7-day POC.
Run an outbound agency?
Become a partner: run Master Inbox for the sales teams you serve and earn a recurring revenue share.
