Notix

Notix is a messaging platform designed for teams in payments, commerce, and SaaS that need to send transactional and marketing email, SMS, and one-time codes at scale. It provides a single send API, an SMTP relay, and a unified suppression list, with a focus on deliverability and operational transparency.

Key Features:

• Email API and SMTP Relay: Send transactional and marketing email via a JSON API with templates, idempotency keys, attachments, batches of 100, and scheduled sends. An SMTP relay supports any application that speaks SMTP.
• One-Time Codes and Verification: Generate and verify OTPs by email or SMS in two API calls, with risk scoring and a pre-send deliverability check that identifies potential blocking issues.
• Marketing Campaigns and Journeys: Manage contact books with double opt-in, run campaigns with review holds, and trigger journeys on join. Unsubscribes are honored while transactional receipts continue to be delivered.
• Operations and Trust: Signed webhooks with HMAC-SHA256, automatic suppression on hard bounces and complaints, DNS verification (SPF, DKIM, DMARC) re-checked every six hours, and role-based access for admins and members.
• Developer Experience: Typed SDKs for TypeScript, Python, PHP, and Go, an OpenAPI reference, and guides for frameworks like Supabase, Firebase, Vercel, and Lambda. The error envelope is consistent across all endpoints.

Use Cases:

• Payments and Lending: Send OTPs via SMS on Nigerian and Kenyan networks, receipts with idempotency keys per transaction, and signed delivery events for ledger reconciliation.
• Commerce: Batch order confirmations, invoices with attachments, and marketing campaigns on a list that automatically excludes bounced or complained addresses.
• SaaS and Platforms: Handle authentication emails (password resets, magic links), product notifications, and welcome journeys from a single integration, with an SMTP relay for legacy components.

What Sets Notix Apart: Notix combines transactional and marketing messaging on one platform with a shared suppression list, ensuring that unsubscribes and bounces are respected across all message types. The platform offers transparent pricing with a free tier of 5,000 emails per month, and a Pro plan at $15 per month that includes 50,000 email units, a 99.9% uptime SLA, and unlimited domains, contact books, and team members. The console provides a unified view of delivery health, reputation, and spend, making it easy for teams to monitor and manage their messaging operations.

Value Proposition: Notix provides a reliable, developer-friendly messaging API that scales with your business, ensuring every message is delivered and accounted for.
