The focused Mailjet alternative for product email
Mailjet is strong when marketing teams and developers share an email platform. Postscale is built for product teams that want transactional sending, inbound routing, masked addresses, and deliverability controls without campaign tooling in the way.
Why teams switch from Mailjet
A smaller surface for transactional email
Postscale keeps the primary workflow to REST sending, SMTP relay, webhooks, suppressions, domains, and logs. There is no campaign builder to configure when your app only needs product-triggered email.
Inbound routing plus product primitives
Mailjet has a Parse API for inbound mail. Postscale pairs inbound parsing with aliases, rules, stored messages, attachment download URLs, and masked addresses so reply workflows can live in one system.
Operational migration controls
Postscale gives teams suppression preview/import, staged DNS cutovers, warming workflows, delivery events, and domain-level diagnostics for moving production mail deliberately.
EU-operated infrastructure for developers
Postscale is operated by DNScale OÜ in Estonia. Primary production service data is hosted in the EU/EEA, with a standard DPA and documented transfer safeguards where infrastructure metadata requires them.
Side-by-side comparison
Familiar developer workflow, lower bundled price, EU/EEA-hosted primary service data.

Migrate from Mailjet in under an hour
Separate product mail
Identify password resets, receipts, alerts, replies, and support flows that should move separately from marketing campaigns or newsletters.
Port API or SMTP sends
Replace Mailjet send calls with Postscale's JSON send endpoint, or move legacy apps first by swapping SMTP credentials.
Move inbound and suppressions
Repoint inbound MX records, configure signed webhooks, import suppressions, and ramp production sending gradually by domain and mailbox provider.
Frequently asked questions
Is Postscale a Mailjet marketing replacement?
No. Postscale does not include campaign design, contact-list marketing, or collaborative email editing. It is a transactional and inbound email API for product workflows.
Does Mailjet already have inbound email parsing?
Yes. Mailjet has Parse API. Postscale's angle is combining inbound parsing with aliases, rules, masked addresses, suppression imports, delivery events, and one product dashboard.
Can I keep Mailjet for newsletters?
Yes. Keep marketing campaigns on Mailjet if that workflow is working. Move product-triggered mail and inbound reply handling to Postscale when you want a narrower infrastructure layer.
What should I migrate first?
Start with a low-risk transactional stream, such as internal notifications or a small product segment. Confirm DKIM, DMARC, bounce handling, and complaint handling before moving critical auth or billing mail.
