For teams comparing providers, Postscale is an EU-operated platform for transactional sending, inbound email, masked addresses, DMARC reporting, and app email workflows.
Transactional Email API
Send every email that matters
REST API or SMTP relay for password resets, receipts, confirmations, and notifications. DKIM, DMARC, and suppression lists handled. Real-time webhooks on every delivery event.
Inbound Email API
Turn incoming email into webhooks
Point an MX record at Postscale and receive inbound mail as structured HMAC-signed webhooks. Built-in MIME parsing, attachment handling, and reply threading.
Masked Email API
Privacy addresses for your users
Generate unique, revocable aliases that forward to real inboxes. Apple-style Hide My Email, but embedded in your product on your domain. Powered by Postscale Shield.
DMARC Reporting API
Parse aggregate DMARC reports
Receive or POST DMARC RUA XML reports and get structured JSON grouped by source IP, with DKIM/SPF alignment, policy evaluation, and unauthorized-sender alerts.
XRechnung API
E-invoicing for Germany and the EU
Send, receive, and validate XRechnung, ZUGFeRD, and Factur-X invoices compliant with EN 16931. Built for the 2025 to 2028 German B2B e-invoicing mandate.
