For a session or an agent acting for the perso... - **sendly-now Analytics API** — Aggregate sending and engagement metrics. Every read is bounded to a window of at most 90 days and cached for 15 minutes. - **sendly-now API Keys API** — Project-scoped sending/API credentials. All four operations are documented; minting and rotation answer with a one-time reveal link rather than the secret, so a delegated caller... - **sendly-now Billing API** — The project's plan, its metered Stripe subscription, and the two Stripe-hosted pages (Checkout and the billing portal). An agent gets a single-use `/go/` link to a hosted page r... - **sendly-now Campaigns API** — Bulk sends to a list, segment, or filtered audience. Served by the `/api/v1` surface (bare payloads, RFC 9457 errors). - **sendly-now Compatibility API** — Drop-in endpoints for the Resend, SendGrid, Postmark, Mailgun and Plunk send APIs, so an existing integration can switch by changing its base URL and key. They are NOT the nativ... - **sendly-now Connections API** — The services a project or a person is connected to: the project's Slack workspace, the domains whose DNS DoDomain manages, and the AI apps connected to a person's account. A con... - **sendly-now Contacts API** — Manage subscribers and per-contact custom data. - **sendly-now Deliverability API** — Why mail from one of your domains is or is not arriving: DNS identity, recent delivery outcomes, and one recipient's suppression state, composed into findings. - **sendly-now Domains API** — Register sending domains and manage SES verification. - **sendly-now Emails API** — Send transactional email and inspect deliveries. - **sendly-now Events API** — Track custom contact events from your application. - **sendly-now Lists API** — Self-serve list membership. These two endpoints accept sending-only keys so they can back a public subscribe/unsubscribe form; list management itself is dashboard-only. - **sendly-now Mailboxes API** — Real receiving mailboxes on your verified domains. Creating one changes how that domain's mail is routed; the messages a mailbox receives are not part of this API. - **sendly-now Members API** — A project's members and their roles. A project is the team: a member is added by the email of an existing Sendly account and joins at once, so there are no pending invitations. ... - **sendly-now Organizations API** — The organizations a person belongs to, each a group of projects: their overview and the merged inbox across their mailboxes. An organization never widens project access; every f... - **sendly-now Projects API** — The project a credential is scoped to, and creating new ones. Configuring an existing project stays a dashboard action. - **sendly-now Segments API** — Saved audiences — a `DYNAMIC` filter re-evaluated on read, or a `STATIC` membership list. Served by the `/api/v1` surface (bare payloads, RFC 9457 errors). - **sendly-now Support API** — Write to Sendly's support team and list what was written, and appeal a project's sending suspension. A ticket reaches the same inbox as the dashboard's support form. - **sendly-now Suppression API** — Project-scoped suppression list. Hard bounces and complaints land here automatically. - **sendly-now Templates API** — Reusable email templates referenced by send operations. - **sendly-now Topics API** — The subjects you mail about, and what each contact has said about them. A topic answer is a standing decision rather than an audience filter: it applies whatever audience a camp... - **sendly-now Usage API** — Current email usage against the monthly and daily limits the platform enforces. - **sendly-now Validation API** — Bulk email validation, billed per address: a bounded synchronous batch, and background runs over a whole list. Distinct from `Verify`, which is the one open, unauthenticated, si... - **sendly-now Verify API** — Open email-validation endpoint (no auth required). Used by the marketing-site verifier. - **sendly-now Webhooks API** — User-managed outbound webhooks for email and contact events. - **sendly-now Workflows API** — Event-triggered automations and the contact runs through them.
