Scaling to Thousands of Agent Mailboxes

Short summary

Nylas Agent Accounts enable scaling email operations across thousands of mailboxes by centralizing configuration in workspaces with shared policies (quotas, rules, allow/block lists). Deliverability is the hard constraint: bounce rates above 5–10% trigger sending pauses requiring support contact; complaint rates above 0.1% trigger review. Implement your own circuit breakers via webhook telemetry, validate recipients, honor unsubscribes, and configure DKIM/SPF/DMARC on all domains to stay ahead of platform limits.

• •Workspace-level policies govern configuration for thousands of accounts at once—no per-grant setup required
• •Bounce/complaint thresholds are strict: account pauses aren't automatic timers, they require support intervention
• •Build proactive monitoring via webhooks (message.delivered, .bounced, .complaint, .rejected) to catch problems before platform enforcement
