FAQ

Common questions about Cloudflare Email Service.

Sending limits exist to prevent abuse and spam and to ensure high deliverability for all users. If you need higher limits, you can request a limit increase by contacting support or reaching out in the Cloudflare Developers Discord . If you exceed your limits, emails may be queued or rejected, and you will receive error responses with rate limit information.

Sender reputation refers to how much inbox providers trust you to send good email to their users and not spam or scam. It is influenced by factors such as your email authentication setup, bounce and complaint rates, sending volume patterns, recipient engagement, and domain and IP history.

Email Service is intended only for transactional emails. We plan to support marketing emails and bulk sender tooling in the future.
