Private early access

SMS API, in private early access.

NoticeAPI is preparing transactional SMS alongside the email API. Join the list to be considered for early access; public SMS sending is not open yet.

A carrier-aware delivery path. We're keeping access invite-only while number, carrier, payment, and handset checks are completed.

No phone number. No text-message consent. No public sending access.

What we're building toward

The developer ease of an email API, with the controls SMS needs.

Early access is for teams with a real transactional or support use case—not a shortcut around consent or carrier review.

Transactional first

Receipts, account security, and support messages come before broad promotional traffic.

Scoped to the project

SMS access is evaluated per project, instead of being added to every existing email key.

Recipient controls built in

Consent, STOP and HELP handling, suppressions, and delivery evidence are part of the path—not an afterthought.

Clear launch boundary

Early access is not activation.

Joining this list does not create a NoticeAPI account, provision a phone number, enable SMS sending, or opt anyone in to text messages.
