Logs include events, message content and inbound email. Upgrading keeps new data longer; data older than your plan’s window is not shown.

Pro prices and overage rates correspond to the 50,000- and 100,000-email monthly packages. Scale packages: $140 for 200,000, $325 for 500,000, or $600 for 1 million emails per month. Contact us for custom volumes and your applicable overage rate.

No surprises
in the small print.

What happens if I exceed my plan?

Free: sending pauses at 3,000 emails in a month and the API returns 429 monthly_quota_exceeded — upgrade to keep sending. Pro and Scale: email keeps flowing. Extra email is billed at your plan’s per-1,000 rate on the next invoice. Set a monthly spending cap in Billing if you want a hard stop.

How do I pay?

By card through Stripe. Invoices and receipts are in Billing; you can change plan or cancel at any time.

Can I add a dedicated IP?

A dedicated IP costs $25 per month, available from Pro, with automatic 30-day warmup and blocklist monitoring.

Do you offer migration assistance?

Contact us about migration assistance for volumes from 200,000 emails per month.
