Ship the receipt. Send the product update.
Use direct sends for app-triggered email. Use broadcasts for subscribed audiences, with unsubscribe and suppression rules enforced.
Can each client use a separate domain and API key?
Yes. Put each client in a project with its own verified domains, keys, templates, contacts, webhooks, logs, and sender state.
Is NoticeAPI for agency cold outreach?
No. NoticeAPI is for transactional email and consent-based marketing. Purchased, rented, or scraped lists are not allowed.
