Limits
Few and boring, on purpose. During the public beta the cloud sends up to 5,000 emails a month; the technical limits below are about protecting the pipeline.
CamelMailer is in public beta. The cloud sends up to 5,000 emails per calendar month, free while we build, and pricing launches soon. Self-hosted stays unlimited. See pricing for the plan we are rolling out next.
The numbers
| Limit | Self-hosted | Cloud |
|---|---|---|
| Message size | smtp_server.max_message_size (default 14 MB) | 14 MB |
| API pagination | per_page capped at 100 | Same |
| API bursts | None imposed by the software | Throttled per key; use the batch endpoints for spikes |
| Emails per month | Unlimited | 5,000 during the public beta |
Spikes belong in batches
If you send bursts (say, a queue worker draining), use the batch endpoints instead of hammering the single-send route:
POST /api/v2/server/messages/batchtakes an array of send requests and returns one result per entry.POST /api/v2/server/messages/with_template/batchapplies one template to many recipients/models.
Details in the messages reference.
Fair use
CamelMailer is built and priced for transactional mail. Bulk marketing violates the acceptable use policy on every plan, cloud or self-hosted.
