- What is the best alternative to Postmark?
- It depends on what you send. For transactional email at a fixed monthly price, Prontuno Standard sends 500,000 emails for $99. For the lowest price per email at most budgets, Amazon SES costs less but needs more setup on AWS. For inbound email or stored templates, Resend covers more.
- Is Prontuno cheaper than Postmark?
- At a $99 monthly budget, Prontuno Standard sends 500,000 emails and Postmark sends 79,000. Prontuno sends more at that budget, but Postmark can cost less at lower volumes. Check your own volume in the pricing calculator. Checked September 26, 2026.
- Can I switch from Postmark without rewriting my code?
- If you send over SMTP, yes: only the host, port, and credentials change. Postmark’s API uses its own field names, such as From, To, and HtmlBody, so each send call needs updating to Prontuno’s from, to, subject, and html fields. If your app sends email from one place, such as a mailer class, updating it is usually a small change.
- When is Postmark the better choice?
- Postmark is the better choice if you process inbound email, such as replies or support mail; you want stored templates edited outside your code; you send marketing email from the same provider; or you need more than 30 days of message history.
- Do I need a new domain to switch from Postmark?
- No. Add your existing domain to Prontuno and publish the DNS records it generates. They use their own names, so your Postmark 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.
