Frequently asked questions

Quick answers to common questions about the platform.

There is no limit to the number of providers you can configure. Zyphr supports automatic failover between providers, so if one goes down, your messages still get delivered.

Zyphr is designed specifically for transactional messaging — emails triggered by user actions like password resets, order confirmations, and notifications. For bulk marketing campaigns, we recommend a dedicated marketing platform.

Message content is stored temporarily for delivery tracking and debugging purposes. Retention periods depend on your plan (7 days on Free, up to 90 days on Scale). Enterprise plans offer custom retention.

Zyphr provides a REST API that works with any language. We offer official SDKs for Node.js, Python, Go, Ruby, PHP, and C#, plus React components for in-app inbox.

When a user registers, verifies their email, resets their password, or performs any auth action, Zyphr can automatically send the appropriate transactional message through your configured provider — no extra API calls needed.
