Is Courier worth the price?

85/100

Courier offers a very generous free Developer tier with 10,000 sends, making it highly accessible for startups and small projects.

The Pro tier's pay-as-you-go model at $0.005 per send is competitive for growing businesses, scaling costs directly with usage. This pricing structure is fair and well-suited for developers and businesses of all sizes looking for flexible notification management.

Hidden Costs & Gotchas

Pro tier costs increase directly with sends

Enterprise features require custom quotes

No annual discounts explicitly mentioned

How Courier Compares to Competitors

Compared to SendGrid's free tier (100 sends/day, ~3000/month) or Twilio SendGrid's Essentials plan (starting at $19.95/month for 50,000 emails), Courier's Developer tier offers significantly more sends (10,000/month) for free. The Pro tier's $0.005 per send is comparable to or slightly lower than some competitors' per-message costs at similar volumes, offering good value for growing usage.
