How should eco DTC brands run SMS marketing compliantly?

Quick answer

Run compliant eco DTC SMS with express written consent (unchecked checkbox, clear disclosure, separate from email opt-in), double opt-in where possible, and honor STOP/HELP on every message. Limit promotional texts to 4 to 6 per month, respect state quiet hours (e.g. Florida, Oklahoma, Washington rules), and prioritize transactional flows (shipping, delivery, replenishment) before blasts. Pair SMS with email per the email marketing guide; never buy lists or text without documented consent.

TCPA (US): marketing texts need prior express written consent; honor opt-out immediately; maintain consent records. CTIA guidelines: clear program description, STOP/HELP support, no SHAFT content issues. State laws (Florida, Oklahoma, Washington, and others): quiet hours, additional consent language. If you sell in the EU/UK, GDPR/ePrivacy rules apply separately.

Document consent timestamp, source, and exact disclosure shown. Klaviyo and similar platforms store this when configured correctly.

How should opt-in capture work?

  1. Unchecked checkbox—not pre-selected
  2. Separate from email marketing opt-in
  3. Disclose: brand name, message type, frequency, “msg & data rates may apply,” STOP to cancel, HELP for help, link to privacy policy
  4. Optional: confirm opt-in via first text (“Reply YES to confirm”)

Never text checkout phone numbers unless they opted in to SMS marketing. Shipping updates may qualify as transactional if truly non-promotional—get legal review if bundling marketing into transactional streams.

Which flows to build first?

  • Transactional: order placed, shipped, out for delivery, delivered
  • Utility: back-in-stock, refill reminder (subscription guide), package delay
  • Lifecycle: welcome SMS (post-consent), win-back for 90-day lapsed buyers
  • Promotional: new drop, limited restock—sparingly, with clear value

Align tone with brand proof; avoid vague “eco sale” language that triggers spam filters and trust issues. Cross-check claims with the compliance guide.

How do you configure Klaviyo SMS?

Enable SMS in account settings, register toll-free or short code, connect list growth forms with compliant disclosure templates, set smart sending and quiet hours, segment SMS subscribers separately from email-only, and sync suppressions on unsubscribe. Test STOP handling before any campaign.

How does SMS pair with email?

SMS for time-sensitive utility; email for story and education. Avoid duplicating the same promo on both channels same day. Use SMS to drive high-intent actions (back-in-stock, cart with high AOV) and email for list growth and nurture. Shared suppressions prevent fatigued subscribers.

What does a compliance audit check?

  • Consent records for every subscriber
  • Opt-in copy matches live forms
  • STOP/HELP tested in last 30 days
  • Quiet hours enabled for all promotional sends
  • No purchased or imported phone lists
  • Transactional vs promotional classification reviewed by counsel if blended

Frequently asked questions

Do I need separate consent for SMS vs email?

Yes. TCPA requires express written consent for marketing texts. Email opt-in does not cover SMS. Use a dedicated unchecked SMS checkbox with message frequency and “msg & data rates may apply” disclosure.

What SMS flows should eco DTC launch first?

Transactional: order confirmed, shipped, delivered. Then: back-in-stock, refill reminder for consumables, win-back for lapsed subscribers. Promotional campaigns only after consent audit passes.

How many marketing texts per month is safe?

Most sustainable DTC brands stay at 4 to 6 promotional texts monthly plus transactional messages. Higher frequency increases opt-outs and complaint rates unless utility is high (subscription management).

What are SMS quiet hours?

Several US states restrict marketing texts before 8am or after 8pm or 9pm local time. Use your SMS platform’s quiet-hours and timezone sending features; default to conservative windows nationally.
