How does Notideus get my emails into the inbox?

Deliverability is a system, not a feature. Notideus walks you through DKIM, SPF, and DMARC setup with copy-paste DNS records, watches your bounce and complaint rates in real time, and surfaces problems before they hurt your sender reputation.

Is there really a free plan?

Yes. The free plan includes 5,000 emails per month, one sending domain, and the full template editor — forever, no credit card required. Upgrade only when you outgrow it.

Can I send both transactional and marketing email?

Absolutely. Password resets and receipts get the same fast lane as newsletters and product announcements. One API, one dashboard, one bill.

How long does it take to set up?

Most teams send their first email within ten minutes: verify your domain, create an API key, and make one POST request. The dashboard walks you through each step.

Do I have to design emails in raw HTML?

No. The built-in block editor lets anyone on your team design responsive emails visually — then developers can send them through the API by template ID.

What happens when an email bounces?

You see it instantly. Every email has a live event timeline, and bounces and complaints are tracked in your analytics so you can act on them before they affect deliverability.
