Email API and SMTP service for transactional and marketing email from a bootstrapped team with long Postmark experience
TrustList summary
Getting email delivered is a specialist problem: reputation, bounces, complaints, suppression, and the slow drift into spam folders that nobody notices until sales drop. Rutba Send handles all of it behind one API and one SMTP endpoint, and the same relay carries your transactional mail and your campaigns so your sending reputation is managed as one thing.
The 3 Applications on One Login
- Send API: The HTTP send API - one call per message, with templates, tagging and the delivery record.
- SMTP relay: The same transport for anything that already speaks SMTP, so an existing app can point at it and change nothing else.
- Bounce & suppression: Bounce and complaint handling with a suppression list, so a bad address stops costing you reputation.
What It Does
- Rest api and smtp endpoint - send however suits you.
- Automatic suppression of bounces and complaints.
- Reputation-aware rate control.
- Templated batch sends.
- Delivery, open, and bounce reporting.
- Unsubscribe handling that stays honoured everywhere.
Built For
- Developers sending transactional email from an app.
- Businesses whose invoices and receipts land in spam.
- Marketing teams needing volume sending with real reporting.
Pricing & Integration
Pricing runs Free, Standard, Scale and Enterprise, starting at $0 up to 1,000 emails / month. Products can be taken separately or together on one account and one invoice.
