EntryWick documentation

Text messages

Settings → Text messages, and SMS or WhatsApp on any event's schedules. Scale plan. Spec: docs/INTEGRATIONS.md §3 v2 (Twilio), docs/PRICING_ENTITLEMENTS.md §7 (sms, sms_monthly).

A reminder can go out as a text: "Spring Gala Sat May 1, 9:00am. Your ticket: https://register.yourorg.org/s/k3Jd92Qa".

Sending

Add a schedule on an event and choose SMS or WhatsApp, with a template of the same kind. Texts go to the phone number on the household's contact — one text per household, like email.

  • 320 characters, links included. Every link becomes a short one on your own address (/s/…), so a ticket link costs about 40 characters rather than 200. A template that renders longer than 320 is refused when you save it; one that only goes over with a real person's details fails with the reason on the message rather than being cut.
  • WhatsApp only allows a business to start a conversation with a template WhatsApp has approved. Create it in Twilio's Content Template Builder, then put its Content SID and the variables it uses in the EntryWick template's settings (content_sid, and content_variables such as {"1": "attendee.first_name", "2": "event.name"}).
  • Counted, never blocked. Each text counts once toward the month's sms total, shown on Settings → Text messages against what the plan includes.

STOP, START and HELP

  • STOP (or UNSUBSCRIBE, CANCEL, END, QUIT) stops texts to that number at once — including a text already scheduled for a minute from now, because we check when each text is sent, not when it was planned.
  • START (or UNSTOP) turns them back on.
  • HELP answers with your name, where to write, and how to stop.

Anything else sent back is not read.

When texts come from EntryWick's shared number, a STOP stops texts from every organization using that number to that phone — the mobile carrier blocks the number for that person anyway. Connect your own Twilio account to have your own.

Your own Twilio account (optional)

Paste your Account SID, auth token and number on Settings → Text messages, then in Twilio set that number's incoming-message webhook to the address the page shows (HTTP POST), so STOP reaches us.

10DLC (United States)

Texting US numbers from an ordinary 10-digit number needs A2P 10DLC registration with the carriers: a brand (your organization) and a campaign (what you send and why). Unregistered traffic is filtered or blocked. The registration belongs to whoever owns the sending number — EntryWick for its shared number, you for your own Twilio account — and takes days to weeks, so do it before the event, not the week of it. Toll-free numbers have a separate verification.
