The EU-operated Resend alternative
Resend is great if you do not need EU/EEA-hosted primary service data, SMTP relay, richer inbound routing, or masked addresses. Postscale adds those workflows behind one API key.
Why teams switch from Resend
EU/EEA-hosted primary service data
Resend is a US (Delaware) company. EU data is replicated but not exclusive. Postscale hosts primary production service data in the EU/EEA, with documented transfer safeguards for limited infrastructure metadata where required.
Richer inbound routing
Resend receiving and Postscale inbound both use shared email quota. Postscale adds aliases, inbound rules, stored message retrieval, and signed webhooks in the same dashboard as sending.
Masked email addresses
No Resend equivalent. If your product has a privacy story, Postscale Shield gives you the 'Hide My Email' primitive on your own domain.
XRechnung / e-invoicing
For teams operating in Germany, the 2025–2028 mandate applies. Postscale ships an XRechnung/ZUGFeRD/Factur-X API; Resend does not.

Migrate from Resend in under an hour
Verify your domain
Same two-DNS-record dance you did with Resend — CNAMEs for DKIM plus SPF include. Our dashboard verifies as soon as DNS propagates.
Swap the client
If you use the Resend JS/TS SDK, move that wrapper to Postscale's REST API. The /emails send body is structurally similar; mostly you're changing the endpoint, field names, and API key.
Add what was missing
Point your MX to mx.postscale.io if you want inbound webhooks, or create your first Shield alias via /v1/shield/aliases. New capabilities light up without a second integration.
Frequently asked questions
Does Postscale integrate with React Email?
Yes. React Email emits plain HTML strings — pass them as html_body to our send endpoint and you're done. Same pattern as Resend.
What about Resend's audiences and broadcasts?
We don't ship marketing broadcasts. Postscale is focused on transactional + inbound + privacy. Keep broadcasts on a dedicated tool; we'll sync at the unsubscribe level.
Is there an official SDK?
Not yet. Use the REST API directly with fetch, curl, or your existing HTTP client. Official SDK packages will be documented once they are published.
Any catch on the free tier?
The free tier includes shared send + receive evaluation volume and masked addresses. See the pricing page for current limits.
Ready to switch?
Free tier covers your evaluation. Migration is a DNS change and an API key swap.
