Choose Courier if…
- You need SMS, push, Slack/Teams, and an embeddable in-app inbox with preference enforcement and provider failover
- You already pay an ESP and want Courier only as the orchestration/routing layer
- You need multi-tenant notification branding or an AI Agent node inside journeys (Business+)
Where Courier is strong
A real alternative, not a straw man.
Courier is a developer notification layer that routes product messages across email, SMS, push, chat, and in-app, billed per send on top of your own delivery providers. People pick Courier when they need product and engineering teams that already have (or want) their own email/SMS providers and need multichannel routing, preferences, and journeys on one API..
- One Send API plus Journeys across email, SMS, push, Slack/MS Teams, WhatsApp, and Courier Inbox, with provider failover
- Public MCP (145 tools), CLI, SDKs, and agent skills so coding agents can send, debug, and manage templates
- Usage pricing at $0.005/send with a 10,000-send Developer free tier and no per-seat or per-channel add-ons
Don't trust the table. Run one journey.
Checklists lie by flattening the work. Build one real path: a trigger, a wait, a branch, a goal, an exit. Then open one subscriber and see what actually happened. That tells you more than any feature row.
- 1. Import a small, consented sample. Not the whole list.
- 2. Recreate one campaign and the audience it actually hits.
- 3. Publish one automation with a goal you can measure.
- 4. Fire a test and read every event on one person.
- 5. Compare the weekly work, not the setup afternoon.

Try it on a real send
Keep the whole list. Pay when you send.
3,000 emails free, no card. Rebuild one campaign, one workflow, and one transactional message before you move anyone. If it feels worse than Courier, stay.
The questions people actually ask
Is Lumail cheaper than Courier?
Sometimes. Lumail is $0 for 3,000 emails, then $20 for 40,000. Courier's number only makes sense after you know what they cap: contacts, seats, a daily send limit, or a feature they hide behind a paid plan. Read the honest take above, then price a normal month and a launch month on both pages.
What is the main difference between Lumail and Courier?
Choose Courier when product notifications need one API plus SMS, push, Slack/Teams, and an in-app inbox with provider failover. Choose Lumail when you want a newsletter platform with capture pages, graph workflows, and transactional email delivered in the same org without a separate ESP bill.
Can I migrate from Courier to Lumail?
Yes. Don't move the whole list on day one. Export a small consented sample, rebuild one campaign and one automation, authenticate your domain, then watch one subscriber go through the run. If that feels right, move the rest.
