SMS Flows for Supplement Brands
The SMS flows that work for supplement brands, when SMS beats email, and the TCPA consent and timing rules for marketing texts.
Article summary
TL;DR
SMS works best for supplement brands on time-sensitive messages: abandoned checkouts, "your supply is running low" reminders, shipping updates and failed payments. Keep it to a few automated flows and let email carry the longer content. Before the first marketing text, get written consent that names the phone number, and send marketing texts between 8 a.m. and 9 p.m. local time.
- Autodialed marketing texts to mobile numbers need the recipient's "prior express written consent" (47 CFR 64.1200).
- Consent cannot be a condition of purchase, and the agreement must name the phone number.
- Telephone solicitations are not allowed before 8 a.m. or after 9 p.m. at the recipient's location.
- The FCC's "one-to-one consent" rule was vacated by the 11th Circuit in 2025; parts of the revocation rule are delayed until January 31, 2027.
- 90% of recovered failed payments come back within 10 days, so a fast SMS on day 0 matters.

| Supply running low | SMS, then email | Short, timely, one link |
| Failed renewal | SMS and email | The bottle is about to run out |
| Shipping and delivery updates | SMS | Expected and welcome |
| How to take the product | Needs space and visuals | |
| Brand story, education | Long content | |

Watch out
A checkbox for SMS that is pre-checked, or required to complete the order, does not meet these rules. Keep SMS consent separate and optional at checkout. Some states add their own texting laws; check them for your customers' states. This is general information, not legal advice.
- SMS box pre-checked or required to orderConsent can't be a condition of purchase.Keep SMS consent separate and optional.
- A promo text scheduled at 10 p.m.Outside the 8 a.m. to 9 p.m. window at the recipient's location.Schedule by the customer's time zone, not yours.
- A customer replies STOPA revocation of consent.Honor it, and stop marketing texts to that number.
Renewal and trial texts touch card network rules too: Tagada follows Visa and Mastercard rules and the laws that apply to payments.
Writing for SMS
- One message, one action, one link.
- Say who you are in the first words.
- Same claim rules as your labels: structure/function claims only, no disease claims421 CFR 101.93, Certain types of statements for dietary supplements.
- Add opt-out wording ("Reply STOP to unsubscribe") in the welcome text and regularly after.
- Limit frequency. A few texts a month keeps opt-outs low.
Example
"Brand: your magnesium runs out in about 5 days. Reorder in one tap, or switch to every 30 days: [link]. Reply STOP to opt out."
Measure SMS
| Metric | Formula | Watch for |
|---|---|---|
| Opt-in rate | SMS subscribers ÷ checkouts or signups | Low: unclear value |
| Click rate | Clicks ÷ texts delivered | By flow |
| Revenue per text | Revenue ÷ texts sent | Compare with email |
| Opt-out rate | Opt-outs ÷ texts delivered | Rising: too many texts |
| Recovery rate (failed payments) | Recovered ÷ failed | SMS vs. email only |
