Frequently asked questions
What email providers does Zyphr support?
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.
Can I send bulk marketing emails with Zyphr?
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.
How does template versioning work?
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.
What deliverability features are included?
Zyphr includes automatic DKIM signing, domain verification, bounce handling, complaint processing, suppression list management, and reputation monitoring — all configured through the dashboard.
