# MailSentry pricing

One flat monthly price per plan. No per-credit billing, no top-ups, no overage invoices.

| Plan | Price / month | Verifications / day | API rate limit |
| --- | --- | --- | --- |
| Free | $0 | 0 | 60 req/min |
| Lite | $47 | 10,000 | 120 req/min |
| Starter | $97 | 100,000 | 300 req/min |
| Professional | $197 | 500,000 | 1,000 req/min |

Quotas reset at 00:00 UTC. A per-IP ceiling of max(200, your plan's per-key limit) requests
per minute applies on top of the per-key limit.

The MCP server at `/mcp` has its own flat limit of **120 requests per minute per IP**. It is
not plan-scoped, so a Professional key gets 1,000/min on REST but 120/min on MCP.

## Free plan and trial

A free account has a daily quota of **0** — it can authenticate, but every verification
returns `403 quota_exceeded`. Confirming the emailed link starts a **7-day free trial** at Starter level (100,000/day)
automatically, with no credit card.

## What counts against quota

- `POST /api/v1/verify` — 1 credit per address.
- MCP `verify_email` — 1 credit; `verify_batch` — 1 credit per address.
- `get_usage`, `get_account` and the MCP equivalents — free.

Verifications that fail on our side (HTTP 502 `provider_error`, or 500) are refunded
automatically, so retrying them costs nothing.

Cancelling stops the renewal and keeps full access until the period you have already paid
for ends.
