Connect from your applications, services, and mail clients using standard SMTP. Configuration and administration are available in the **Ruach Control Panel**. ### What is an SMTP server? SMTP (Simple Mail Transfer Protocol) moves email between mail servers. Sending large volumes from a generic mailbox often leads to throttling, poor deliverability, or spam classification. ### Service advantages Ruach Email Delivery is designed for operational clarity and sender reputation at scale: * Each organization's sending reputation is isolated from other tenants without requiring a dedicated IP. * Dedicated sending reputation and suppression lists per account. * Sending pools aligned to your traffic profile. * Multiple accounts for separate brands or environments, managed from the Control Panel. * **Transactional credentials** - Use SMTP credentials issued for transactional sending **only** for transactional mail (for example order confirmations, password resets, and system alerts). Sending marketing or bulk promotional mail through those credentials can damage reputation signals and **deliverability**. Use credentials and paths intended for promotional or campaign mail when the Control Panel separates them. ### Why enterprises choose Ruach Email Delivery * **Pools and reputation** - Sending pools matched to workload; reputation separated from other customers. * **Deliverability** - Built for strong inbox placement while discouraging abuse and supporting compliant, quality sends. * **Support** - The Ruach team can assist with deliverability and integration questions. * **Reliability** - We operate the sending platform and focus on consistent quality at high volume. * **Control Panel** - Manage accounts, authorised sending domains, reputation, and suppression lists. ## Who this is for Ruach Email Delivery fits **enterprise and mid-market teams** that need a dependable outbound SMTP path integrated into internal systems, SaaS products, and customer-facing applications.
