Bulk SMS Global Margin Threshold

Bulk SMS Global bills per message, so agency margin is a function of route cost against retainer price. Premium Route SMS runs $0.026 per message at 1 to 9,999 monthly, drops to $0.02 at 10,000 to 99,999, and $0.016 at 100,000 to 499,999. A client sending 40,000 messages monthly costs roughly $800 in route fees; a $1,500 retainer leaves about $700 gross before labor. Below the 10,000-message band, the same retainer can be underwater. Before signing, pull the client's 90-day send volume, map it to the correct band, and set the retainer at 1.8x to 2.2x projected route cost. Agencies that skip this step discover the compression after delivery starts, when renegotiating price is hardest.
