FAQ
Questions, answered.
What actually sends the mail?
Notix runs managed sending infrastructure and gives you the API, the dashboard, the templates, the contact books and the suppression list on top of it. You get the deliverability without writing the plumbing around it.
Can I use more than one sending domain?
Yes. Verify as many sending domains as you need. Each gets its own SPF, DKIM and DMARC records and its own reputation, so a problem on one domain never touches another.
Do I pay for storing contacts?
No. Contact books, lists and suppression entries are not metered. You pay for emails that leave the building.
What happens when I go over the included allowance?
Nothing stops. Sending past the included units is metered per unit and appears on the same invoice. There is no per-day cap on a paid plan.
How do I move off Notix later?
Export contacts and suppression as CSV, and point the SMTP relay somewhere else. The API is a plain JSON endpoint with a published OpenAPI reference, so there is no format you cannot read.
Is there an SLA?
Yes, on Pro. Notix commits to 99.9 percent monthly availability for the sending API and the SMTP relay, measured at the public status page. If a month falls below that, you receive 10 percent of that month’s subscription as credit, and 25 percent if it falls below 99 percent. Ask for the credit at hey@usenotix.dev within 30 days. The Free plan is provided on a best-effort basis, and the quickstart states current limits plainly.
