Sendfeather is a transactional email service for product teams. Send receipts, one-time codes, and notifications over SMTP or a single HTTP API call — every message gets a delivery timeline from accepted to delivered, with bounces and complaints handled automatically. Every paid plan includes hosted mailboxes for your domain, so sending and receiving live in one place. Pricing is flat and published: $7/month for 10,000 emails, $15 for 50,000, and $29 for 100,000 — yearly billing is ten months for twelve; metered overage means sending never stops to ask for an upgrade. Side-by-side pricing with the major providers, each checked from their own pricing page with dates: sendfeather.com/compare
