Rate limits

Requests are limited in two layers: short-term limits at Cloudflare’s edge, per account and per IP, and hourly and 30-day quotas behind them. A limited request returns 429 with a Retry-After header in seconds.

The edge limits absorb floods and are not published as fixed numbers. The quotas you are likely to meet:

Limit	Value
Messages received	Your plan’s monthly allowance, from 3,000 on Free to 20,000,000 on Fleet
Message bodies and attachments read	Per hour, scaled to the plan, at least 2,000
Mail sent	60 an hour per account
Pairing-code lookups	10 failed in 5 minutes
Checkouts opened	20 a day
Custom domain checks	60 an hour
