Cloudflare Email
Send through Cloudflare Email Service. Sending only, without delivery tracking.
Provider type: Cloudflare Email
API Token: a Cloudflare API token that can send email for the account
Account ID: 32 hex characters
Webhook: none (Cloudflare has no delivery webhook)No delivery tracking
Cloudflare publishes delivery events to Cloudflare Queues, not to a webhook, and its REST API returns no message id Senlo could match them with. Emails sent through Cloudflare stay at Sent in the delivery log: no Delivered status, and bounces and spam complaints that happen after sending are not recorded or suppressed. If you need those, use Resend, Postmark, SendGrid or Mailjet.
1. Set up sending in Cloudflare
- Your sending domain must use Cloudflare DNS, and be onboarded for Email Sending on the same account as the API token (Cloudflare dashboard → Email Service).
- Sending to any address, not only your verified ones, needs a paid plan: at the time of writing, Workers Paid, with 3,000 emails a month included and the rest billed by Cloudflare. Hard bounces count toward that quota. Plans and limits change, so check Cloudflare's Email Service pricing.
Until the domain is set up, sends fail at Cloudflare and show FAILED in the delivery log with Cloudflare's error code. email.sending.error.authentication.not_entitled (10105) means the account's plan does not include sending.
2. Get the token and account ID
- Create an API token (My Profile → API Tokens) with permission to send email for the account. Copy it; Cloudflare shows it once.
- Copy your Account ID from the account home page (32 hex characters).
3. Add the provider in Senlo
- Open Providers → Add Provider, Provider Type: Cloudflare Email.
- API Token and Account ID: from step 2.
- Click Create Provider, then select it in your workspace's Settings.
What Senlo still tracks
Cloudflare answers every send with what happened to each recipient right away. When it reports a permanent bounce (an address refused for good), Senlo marks the email Bounced and adds the address to the suppression list, so it is not mailed again. The send is not retried.
Opens and clicks are counted by Senlo's own tracking, as with every provider.
