Inbox deliverability, first

We show you the exact DKIM, SPF and DMARC records to copy into your DNS, then check DKIM automatically until the domain is verified, so receiving servers can tell your mail really comes from you.

app.tratto.email/domains

The domain verification screen: SPF and DMARC DNS records with plain-English explanations of what each one does

One-line integration

One HTTP call sends an email: official SDKs for Node.js, Python and PHP, or plain curl. No SMTP server to run or keep patched.

Every event, as a webhook

Signed webhooks for deliveries, opens, clicks, bounces, complaints and unsubscribes, retried when your endpoint doesn't answer. Per-campaign stats in the dashboard.

Template engine

Write templates in HTML or Markdown with a live preview. Every change to the content is saved as a version, and a test send shows the real email before you publish.

app.tratto.email/templates

The template editor's live preview, rendering a real HTML invoice email with unfilled {{variable}} placeholders flagged

Campaigns and automations included

The same API that sends your receipts runs your newsletters and drip flows. One integration, no second tool to buy.

EU-hosted email infrastructure, GDPR-native

Named regions, not an adjective: the API runs on Google Cloud europe-west1 (Belgium), the database sits in the eur3 EU multi-region, and delivery goes out through AWS SES eu-west-1 (Ireland). Every sub-processor is listed in the footer. One-click unsubscribe is built into every campaign and flow.

→ POST /v1/campaigns/{id}/send { scheduledAt }: draft until you schedule it

Email campaigns and automations from the same API

One API.Also your newsletter.

Connect Tratto once and your whole stack sends through it: receipts, product updates, drip sequences, one-off campaigns. No second platform to buy, no domain to re-authenticate, no separate bounce list to reconcile.

DevA developer connects the API once.

TeamThen anyone on the team builds and schedules campaigns from the dashboard, no code required.

Audience segmentation by field, tag, or custom property, not just static lists
CSV import for existing contact lists, deduplicated on the way in
Schedule sends or trigger drip sequences from the same dashboard
Real-time delivery, open, click, and bounce stats per campaign

REST API for transactional email

One POST to send.A webhook when it's delivered.

Plain REST with JSON: call it with curl, or use the official Node.js, Python and PHP SDKs. Every error carries a stable code, and a suggestion when the fix is known.

Idempotency-Key on sends, so a retry never sends twice
Errors with a stable code and a suggestion
Cursor pagination, not offset
Test keys with a delivery simulator
