EventSend Retainer Fit Matrix

Map each client's monthly event volume against EventSend's published tiers before quoting a retainer. A local e-commerce shop pushing a few thousand order and payment events fits the Free tier (2,500 events/month, 2 seats, 3 team destinations, 1 source, 7-day retention), so the agency margin comes entirely from the $1,800 Starter Event Setup fee and not from the platform. A client crossing 50,000 events/month moves to Starter at $12/mo with unlimited seats and sources plus 30-day retention, which is where a monitoring retainer starts carrying real recurring value. Growth at $29/mo covers 150,000 events/month. The trap is signing a client whose volume sits just under a tier ceiling: overage behavior is not published, so agencies should instrument event counts during the first 30 days and re-tier before the retainer renews. Treat the tier boundary, not the feature list, as the pricing decision.
