Zyntra provides a read‑only email testing API that lets developers automate sign‑up, password‑reset, magic‑link and OTP flows. By sending test emails to team‑specific addresses, teams can retrieve email content, links and attachments over a simple REST endpoint. The service includes free tools like SPF/DKIM/DMARC checking, an email header analyzer, and SDKs for popular test frameworks. Plans range from a free tier with 150 emails/month to paid tiers with higher limits and longer retention.
