Postscale vs Mailgun

The EU-hosted Mailgun alternative

Same developer-first API, same inbound parsing, same EU deliverability — with EU/EEA-hosted primary service data and without paying for Inbound and Validations as separate products.

Why teams switch from Mailgun

EU entity, EU/EEA-hosted primary service data

Mailgun is a Sinch US subsidiary. Postscale is operated by DNScale OÜ (Estonia). Primary production service data is hosted in the EU/EEA, with documented transfer safeguards for limited infrastructure metadata where required.

Flat pricing without add-ons

Mailgun charges separately for Inbound Parse, Email Validations, and Dedicated IPs. Postscale ships inbound, masked addresses, and validations included from paid tier one.

Developer-first, same shape

Both APIs are REST with multipart/form data or JSON, both speak SMTP, both fire event webhooks. The migration is mostly s/api.mailgun.net/api.postscale.io/ and a new key.

Proper EU deliverability

Postscale is tuned for European mailbox providers, with deliverability controls, authentication, and warming workflows built for EU senders from day one.

Side-by-side comparison

Same developer experience, lower price, EU-hosted.

Migrate from Mailgun in under an hour

1

Reuse your DNS

Leave Mailgun's DNS records in place during cutover. Add Postscale's CNAMEs and SPF include alongside — both pass simultaneously, no downtime.

2

Swap endpoint and key

Replace api.mailgun.net calls with api.postscale.io. Field names line up almost one-to-one for the /messages endpoint; the inbound parse payload is even closer.

3

Cut inbound MX

Point your MX from mxa.mailgun.org to mx.postscale.io. Webhooks keep firing with the same general shape. Remove the Mailgun records once traffic confirms.

Frequently asked questions

Do you handle EU-to-non-EU sending transparently?

Yes. Primary Postscale service data is hosted in the EU/EEA, while email delivery still reaches recipients globally. Delivery to US, APAC, and LATAM inboxes uses normal internet mail routing and documented infrastructure safeguards.

What happens to my Mailgun event history?

Stays on Mailgun for as long as your retention there allows. Postscale starts fresh on cutover; if you need unified analytics, export Mailgun's event history to your own store before switching.

Will my webhook handler work without changes?

Probably with minor field renames. Our event payload shape is close to Mailgun's but not identical — we document every field mapping in the migration guide.

Is there a free tier big enough to test with production traffic?

Yes. The free tier handles 1,000 sends/month which is more than enough to validate routing, webhooks, and templates against real recipients before you flip DNS.

Ready to switch?

Free tier covers your evaluation. Migration is a DNS change and an API key swap.
