SaaS APIs charge per mailbox forever—even once onboarding is complete. Riposte installs inside your VPC so infrastructure is your only lever: you size Postgres, Redis, and compute the same way you do the rest of your stack.
Teams replacing Cloud-based email APIs regularly see 70–90% savings by swapping $1.50+/account fees for a single Kubernetes deployment. Those savings compound when you factor in data-egress, compliance reviews, and the ability to reuse observability you already pay for.
Because Riposte runs alongside your product you keep costs predictable: pause tenants, right-size workers, or reserve compute without filing a vendor ticket.
