Check your own volume in the [pricing calculator](https://prontuno.com/pricing/#comparison-heading) . Checked September 26, 2026. Can I switch from Mailgun without rewriting my code? If you send over SMTP, yes: only the host, port, and credentials change. Mailgun’s API uses similar field names, from, to, subject, and html, but sends them as form data. Prontuno takes JSON, so each send call needs updating. If your app sends email from one place, such as a mailer class, updating it is usually a small change. When is Mailgun the better choice? Mailgun is the better choice if you route inbound email to your application; you validate addresses before sending; you want phone and chat support; or you send marketing and transactional email together. Do I need a new domain to switch from Mailgun? No. Add your existing domain to Prontuno and publish the DNS records it generates. They use their own names, so your Mailgun records keep working until you finish switching. Does Prontuno track opens and clicks? No, by design. Prontuno sends your links and content exactly as written, so password reset and sign-in links are never rewritten through a tracking domain, and no tracking pixel is added. Delivery, deferral, and bounce events are still reported in your logs and webhooks. To measure clicks, add a parameter to links on your own domain and record it in your app. Can I send marketing email with Prontuno? No. Prontuno is for transactional email only, such as password resets, receipts, and account alerts. Every account is reviewed, which keeps marketing mail off the shared IPs. Newsletters and campaigns need a separate provider.
