Estimates are directional and based on public seat pricing assumptions ($8.40/mailbox for Google Workspace and $7.20/mailbox for Microsoft 365).
Yes. Every plan includes unlimited mailbox connections. Pricing is based on operational capability, not mailbox count.
All plans can use IP addresses. IPs are billed separately as add-ons, and can be assigned to sending workflows based on your setup.
Automated IP rotation is available on Scale and Agency. Starter supports IP add-ons, but rotation is not automated on that plan.
IP rotation automatically spreads outbound traffic across multiple healthy IPs based on policy rules and sending limits. Instead of relying on a single IP, volume is distributed to reduce reputation concentration and keep sending more stable.
It helps prevent overloading one sending identity. By distributing traffic across healthy IPs and rerouting when risk signals increase, teams can reduce sudden placement drops and maintain more consistent inbox performance.
Not necessarily. Many teams start with Starter and a simpler setup, then move to Scale or Agency when volume and risk controls require automated IP rotation.
Yes. All plans support IP add-ons. If you need policy-driven, automated IP rotation and routing, Scale and Agency are the right plans.
Most teams complete DNS auth, inbox connections, and first warm-up flows in under an hour.
Yes. We provide migration guidance for domain transfer, reply routing, and workflow parity so you can switch with minimal downtime.
