Frequently asked questions
Quick answers to common questions about the platform.
How many providers can I connect at once?
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.
Can I use Zyphr for marketing emails?
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.
Does Zyphr store message content?
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.
What programming languages are supported?
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.
How does auth-triggered messaging work?
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.
