Frequently asked questions

Zyphr currently uses AWS SES for email delivery, providing enterprise-grade deliverability and reputation management. Additional providers (SendGrid, Postmark, Mailgun) are on the roadmap with automatic failover.

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

Each template can have multiple versions. You can preview changes, run A/B tests, and roll back to previous versions instantly. Templates use Handlebars syntax for variable substitution.

Zyphr includes automatic DKIM signing, domain verification, bounce handling, complaint processing, suppression list management, and reputation monitoring — all configured through the dashboard.
