Can I treat work emails differently?

Yes. enrich.person resolves the email to a company, then a filter or a branch routes business signups somewhere louder than personal ones.

How do I stop duplicate entries?

Pass the email as idempotencyKey; the gate enforces uniqueness, so a double-submit counts once and keeps positions honest.

Can I keep a full copy of the list?

Fan out: send the alert to a chat channel and the same event to Postgres, so the canonical list lives in your own database.

Track waitlist signups in Slack

See who joins the waitlist as it happens — with their position and where they came from — so launch outreach starts the day they sign up, not after the next export.

the event

You emit waitlist.joined with this shape. The TypeScript SDK keeps the call type-safe, and the event is stored whole — so every field below is available to the pipeline by name.

emit it

From your code with the TypeScript SDK — or any language over the REST endpoint and signed webhook ingress.

emit waitlist.joined

import { ingest } from "@ingestlayer/sdk";

await ingest("waitlist.joined", {
  email:    form.email,
  position: list.length + 1,
  referrer: req.headers.referer,
}, {
  idempotencyKey: form.email,   // one slot per email
});

route it to Slack

Post to any channel in your workspace. Connect once with OAuth, pick the channel per pipeline.

01
connect your workspace
Authorize the ingestlayer Slack app over OAuth from the destinations page. We hold only a channel-scoped bot token, in-region, in the same KMS as your other credentials.
02
pick a channel
Choose any public channel, or invite the bot to a private one. The channel is set per pipeline, so different events can land in different places.
03
map the message
Reference event fields with $event.* in the message template. The default renders a titled block with the event name and its key fields.

notes

Slack rate-limits to roughly one message per second per channel; bursts are queued and retried, never dropped.
The bot must be a member of a private channel before it can post there — invite it explicitly.
Block Kit caps a message at 50 blocks and 3000 characters per text field; oversized events are truncated with a link to the full payload.
