SendPorter

Transactional email platform

Every email, tracked like a parcel.

SendPorter gives your product one REST API and one SMTP relay. Every message is DKIM-signed, carried through a managed delivery pipeline, and accounted for — from accepted to opened.

Form 02 — Capabilities

The whole delivery job, in one manifest.

Everything between “user clicked buy” and “receipt in inbox” — without stitching together three vendors.

01

Send

One REST API and one SMTP relay — point either at your app once, and every message shares the same signed, tracked pipeline.

02

Authenticate

Register a domain and we generate its DKIM key, recommended SPF record, and DMARC visibility — no cryptography homework.

03

Bring your own cloud

Connect a domain to its own AWS account: its own SES identity and sending reputation, isolated from every other domain on the platform.

04

Compose

Store templates with variables, or design them visually in the drag-and-drop builder with AI-generated imagery.

05

Receive

Gmail-style mailboxes on your own domain — send, receive, reply, forward, and file into folders, right inside SendPorter.

06

Track

Queued, delivered, bounced, opened, clicked — every event on a timeline per message, plus HMAC-signed webhooks to your app.

07

Protect

Hard bounces and complaints suppress automatically. Deferred mail retries on a backoff schedule until it lands.

08

Grow

Contacts, lists, and CSV import, with scheduled campaigns and per-link click reports — for when transactional isn't the whole job.

Form 03 — Dispatch

Send your first email in under a minute.
