Brevo Agent Margin Threshold

Brevo's per-agent pricing model creates a hard ceiling on retainer margins for agencies reselling chat management. At $41/agent/month (or $33 annually), each additional agent needed to handle client conversation volume directly erodes profit. For example, an agency charging a $500 monthly retainer for chat support with two agents on the Pro plan faces a $66 to $82 cost, leaving a healthy margin. But if client volume spikes to require four agents, the cost jumps to $132 to $164, compressing margin to near 70% before other overhead. This framework helps agencies calculate the maximum number of agents a client's retainer can sustain, factoring in Brevo's per-agent pricing and the client's expected chat volume. It also guides whether to pass through agent costs or bundle them into a higher retainer, ensuring sustainable profitability as client needs scale.
