Send SMS Campaigns

Bulk SMS to your customer list via Twilio. Audience filters, segment by spend, dedup, unsub footer.

Updated 26 June 20266 min read

SMS is the highest-ROI channel for raffle retention. Open rates approach 100%, response is fast, and your existing customer list already opted in at signup. The Marketing > SMS section lets you compose, audience-target, and send.

Pre-requisites

  • Twilio Account SID + Auth Token + sender phone configured in Integrations.
  • Customers must have phone_verified = true and sms_opt_out = false. Both flags are managed by the customer at signup and via their /account page.

Audience segments

  • All opted-in customers: your full SMS list. Use sparingly (max once a week).
  • Recent buyers (30 days) bought at least one ticket in the last 30 days, making them your highest engagement audience.
  • Lapsed (30+ days)customers haven’t purchased in 30+ days; they’re best suited for win-back campaigns with a discount code.
  • Winners, meaning anyone with at least one win, show high loyalty and are often eager to play again.

Message anatomy

160 characters max (anything longer counts as two messages and doubles your cost). Structure:

  1. Hook: emoji + urgency. “⏰ Final 24h”
  2. Specific prize, e.g. “BMW M4” not “huge prize”
  3. One link (short): luckyturbo.co.uk/bmw
  4. STOP-to-unsub, which is legally required

Example: “⏰ Final 24h to bag tickets on the BMW M4 draw, 99p each, instant wins all weekend. Play now → luckyturbo.co.uk/bmw. STOP to unsub” (158 chars).

Compliance non-negotiables

  • Opt-in capture. Customers opt in at signup (separate checkbox, never bundled). Already wired by default.
  • STOP to unsub.Every campaign message must include it. Twilio routes incoming STOP messages back; we flip the customer’s sms_opt_out automatically.
  • Sender identification.If you’re sending from a short code, the brand name must be in the message. With a long code (E.164 phone), it can be in the link or sign-off.
  • Quiet hours. UK consumer code says no SMS between 9pm and 9am. The Worker scheduler respects this and queues out-of-hours sends to the next morning.

Cost

Twilio UK long-code SMS is ~£0.04 per message at typical retail rates. 1,000 customers = £40 per campaign. Conversion of 1–3% is realistic on a relevant offer, so £40 to drive £150–£500 in tickets is a strong ROI.
