Platform

One platform for all your product email

From OTPs to newsletters. Send via API, SMTP, or the dashboard — everything logged in one place.

REST API & SDKs

TypeScript and Python SDKs, or plain REST. Batch up to 100 emails per request, schedule with scheduledAt, and retry safely with an Idempotency-Key.

SMTP relay

Connect existing backends — Supabase Auth, Laravel, Django, NextAuth, or WordPress — by swapping SMTP credentials.

Real-time webhooks

Delivered, opened, clicked, bounced, complained, and more. Signed with HMAC SHA-256 and retried automatically on failure.

Campaigns & contacts

Manage contact books, send campaigns to thousands of contacts, schedule, pause, or resume. One-click unsubscribe included.

Templates & visual editor

Design emails in a visual editor, save them as templates, then send via API with a templateId and variables.

Logs & analytics

Search emails by recipient or status, see each email's event timeline, and monitor bounce and complaint rates.

Integration

Up and running in minutes

Create an API key in the dashboard, verify your domain, and send. Copy-paste examples included.

import { F14 } from 'f14';

const f14 = new F14(process.env.F14_API_KEY);
