Best for / Not for

BEST FOR

  • Applications sending verification, password reset, receipt, or notification email
  • Developer teams that want an API-first email service
  • Products that can separate transactional and marketing email costs

NOT FOR

  • Teams looking for a mailbox provider
  • High-volume programs that need a negotiated delivery operation
  • Products that assume marketing contacts are included with transactional email

Where it fits in your stack

Connects authentication and backend events to customer inboxes through an email API, verified sending domains, and delivery webhooks. It replaces self-hosted SMTP delivery, but not a team mailbox or a full marketing automation platform.

Pricing

Pricing model: Volume-based. Pro is $20/month (50,000 emails); Scale is $90/month (100,000).

Free allowance: $0 — 3,000 emails per month, capped at 100 per day, 3 domains, and 30 days of data retention.

Overage rule: $0.90 / 1,000 emails (when pay-as-you-go is enabled). Automations are $0.0015/run.

Trade-offs

  • Marketing email is a separate product billed by contact count (Free 1,000 contacts; Pro Marketing $40/month for 5,000). If you send both password resets and newsletters from the same product, you pay two bills.
  • Daily limits can constrain testing and early production traffic on the free tier
  • Deliverability still depends on domain configuration and sending practices
