Courier vs SuprSend: 2026 notification platform comparison

Last updated: November 2026

Short answer

Courier is the notification platform your product, marketing, and engineering teams share. Marketers build journeys and edit content in visual tools, engineers work in the API, CLI, and MCP server, and both work on the same objects. Send one template to one person through the Send API and Courier counts one send, however many channels it reaches. SuprSend counts every channel a notification reaches separately.

• Price shape. Courier's Developer plan is free for 10,000 sends a month, and Business is $0.005 per send, pay as you go. SuprSend's paid plans are billed annually: Essentials is $1,200 a year and Business $3,000, each with 50,000 notifications a month (suprsend.com/pricing). Email plus in-app for 500,000 events is $2,500 on Courier and $5,000 on SuprSend Business.
• Preferences on every plan. Courier's preference center, topic and channel choices, and digests come with every plan, including the free one. SuprSend puts user preferences and batching on Business.
• Failover you don't write. Courier fails over between providers automatically, so a provider outage doesn't stop a send.

Courier vs SuprSend at a glance

Where Courier wins

One platform for product and lifecycle work. Your engineers trigger sends from code. Your growth team builds onboarding, renewal, and upgrade flows in Journeys and edits content in Design Studio without filing a ticket. Everything in the UI is on the API, so a marketer, an engineer, and an AI agent working through the MCP server all change the same journey. Here's how journeys work as code.

Preferences and digests aren't an upgrade. Courier's preferences come as a hosted page, an embeddable component, or headless APIs, with per-topic channel choices and tenant defaults, on every plan. Map a template to a topic and Courier enforces the user's choice on every send. On SuprSend, user preferences and batching start at Business, $3,000 a year up front. See how to launch a hosted preference center.

Failover you don't write. Courier sits on top of the providers you already pay for, including SendGrid, Twilio, SES, Firebase FCM, and APNs, across 50+ integrations. Add a backup per channel and Courier fails over when the primary can't deliver. See how push fallbacks work.

Testing that tells you what worked. Experiments run 2 to 10 template variants at a send point inside a journey, with per-variant metrics and recipients who stay in their variant. You read the results in the journey you built the test in.

Your customers can design their own messages. Courier Create is the same editor, embeddable and white-labeled inside your product. For multi-tenant SaaS, that's the difference between a feature and a support queue. Twilio, LaunchDarkly, CircleCI, and Nav run on Courier. Here's multi-tenant notifications in practice.

Pricing

Prices checked November 2026.

Courier (courier.com/pricing): Developer is free for 10,000 sends a month, with Journeys, Broadcasts, preferences, the MCP server, the CLI, and the SDKs. Business has no platform fee and charges $0.005 per send on any channel, pay as you go. It adds AI Translations, the AI node, and EU data residency. AI features run on AI credits at $1 per 100, billed separately from sends. Enterprise is custom volume pricing.

SuprSend (suprsend.com/pricing): Essentials is $100 a month billed annually ($1,200 up front), with 50,000 notifications a month and $2 per additional 1,000. Business is $250 a month billed annually ($3,000 up front), with 50,000 notifications and $5 per additional 1,000, and adds user preferences and batching. Multi-tenant features are Enterprise or a Business add-on.

What does 500,000 notifications a month cost?

Take 500,000 product events a month, each sent by email and in-app. Courier counts one multi-channel template sent to one recipient through the Send API as one send: 500,000 sends at $0.005 is $2,500. SuprSend counts each channel, so that's 1,000,000 notifications. On Business, the tier with user preferences, that's $250 + 950 × $5 = $5,000.

In a journey, each Send node delivers one channel, so a journey that sends email and in-app counts two sends.

Light months favor Courier too. At 20,000 emails a month, Courier is $100. SuprSend Business is $250, paid a year in advance.

When should you choose Courier?

• You want product, marketing, and engineering on the same journeys and templates, with visual tools for some and the API, CLI, and MCP server for others.
• You want preferences, digests, and an embeddable preference center without moving up a tier.
• You need automatic failover across 50+ integrations and a drop-in Inbox, billed per send with no annual commitment.
