A quick, predictable API
Official SDKs, or plain HTTP. Verify a domain, create a scoped key, and send.
Add a handful of DNS records and we confirm DKIM and your return path.
Generate a scoped key in the dashboard. Rotate or revoke it whenever you need.
One authenticated request to /v1/email, then follow it through the activity log.
curl https://api.mailhuset.com/v1/email \
-H "Authorization: Bearer mh_live_..." \
-d '{"from":"you@yourapp.com","to":"user@example.com",
"subject":"Reset your password",
"template":"password-reset"}'Deliverability, handled
Guided DKIM, SPF and DMARC setup with live verification. Every outgoing message is DKIM-signed so mailbox providers can verify where it came from.
Hard bounces and complaints are suppressed automatically, so you never burn your reputation sending to dead addresses.
Email processing and storage use EU regions by default, with locations and sub-processors documented clearly.
Pricing
Every plan includes authenticated sending, templates, signed webhooks, suppression and the complete activity log. Paid plans add broadcasts, inbound email and higher account limits.
