The EU-hosted Mailgun alternative
Same developer-first API, same inbound parsing, same EU deliverability — without the US processor relationship and without paying for Inbound and Validations as separate products.
Why teams switch from Mailgun
EU entity, no US parent
Mailgun is a Sinch US subsidiary. Postscale is DNScale OÜ (Estonia). CLOUD Act doesn't reach us; Schrems II assessments aren't required for EU-to-EU processing.
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
Our sending IPs are based in EU data centers with ARIN/RIPE EU allocation. German, French, and Nordic ISPs treat EU-origin IPs as higher-reputation than US fly-throughs.
Side-by-side comparison
Same developer experience, lower price, EU-hosted.

Migrate from Mailgun in under an hour
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.
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.
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. Our edges sit in EU data centers and we peer with major backbones globally. Deliverability to US, APAC, and LATAM inboxes is indistinguishable from sending via a US provider — we just don't store your data there.
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.
