EU data residency
Messages, events and recipient data are stored in the EU. Processor DPA, configurable retention, and recipient/tenant erasure are first-class ā not an add-on.

Data-rich templates
Send template_id + JSON. Sandboxed, versioned templates with layouts and
partials, previewable against sample data ā no redeploy to change a template.

Events & webhooks
A per-message timeline from accepted to delivered, bounced or complained. HMAC-signed, retried, replayable webhooks built from our own event store.
š”ļø
Deliverability, protected
Domain authentication with drift checks, sender vetting, suppression lists, and per-tenant bounce/complaint monitoring with automatic pause.

A simple, honest API
Idempotency keys, cursor pagination, a stable error envelope and a request_id
on everything. Bearer keys, scoped, live/test, rotate instantly.
š
Open SDKs
MIT-licensed PHP SDK plus Symfony & Laravel Mailer transports. Drop it in and keep your framework's mailer ā single or batch.
Why EU-first actually matters
Most transactional-email providers route your recipients' data through the US. PufferPost keeps it in the EU end to end: our stack is self-hosted in Europe, and AWS is used only to hand mail to the delivery network. That makes your DPA simpler and your GDPR story honest.
