Shared domain allowance
Free verifies 1 sending domain. Pro includes 10 and Scale includes 100 in the same bundled workspace plan.
One API key. Every product gets a verified sending domain.
You ship more than one product — or send for more than one client — and each brand needs mail from its own domain. Verify every domain in a single account and send from all of them with the same key, sharing one set of logs, suppressions, and webhooks.
- Shared domain allowance
- Free verifies 1 sending domain. Pro includes 10 and Scale includes 100 in the same bundled workspace plan.
- SPF and DKIM, generated for you
- NoticeAPI generates the ownership, SPF, and DKIM records each domain needs. Publish the shown records at your DNS provider, then verify them in NoticeAPI.
- Any address on a verified domain
- Once a domain verifies, send from any local part and display name on it — no per-address setup.
More domains, same safety model
Adding a domain doesn't buy a shortcut. Every verified sender runs through the same ramp limits, suppression list, delivery logs, and deliverability autopilot.
From one domain to five hundred, on the same account.
Every plan verifies domains the same way; what changes as you grow is how many you get. Existing domains never redo DNS when you move up.

SPF and DKIM, generated for you
NoticeAPI generates the ownership, SPF, and DKIM records each domain needs. Publish the shown records at your DNS provider, then verify them in NoticeAPI.
Any address on a verified domain
Once a domain verifies, send from any local part and display name on it — no per-address setup.
Upgrades don't touch your DNS
Move from Free to Pro and your verified domains stay put: new headroom, the same records you already published.
Questions before you ship.
How many domains can I add?
Free verifies 1. Paid plans include at least 10, Scale includes up to 100, and extras are $1/month until the plan's self-serve ceiling. Enterprise supports up to 500 by agreement.
Do I need to redo DNS when I upgrade?
No. Existing verified domains stay configured. Higher plans raise your domain count and quota without touching the DNS you already published.
Can each domain send both transactional and marketing email?
Yes, once the domain is verified. Transactional messages go through the send API or SMTP relay; audience updates go through broadcasts and automations.
