01The mechanism

Why this template works

SMS marketing has 90%+ open rates and 30%+ click rates — multiples of email — but only if you have permission to send. This template captures phone-number opt-in alongside email, with TCPA-compliant disclosure ("By submitting, you agree to receive automated marketing texts. Reply STOP to unsubscribe."

) so the list is legally usable. Pair with a phone-number-required discount: visitors get the discount only if they opt in to texts. Stores running this typically build a 2-channel (email + SMS) list 3-5x faster than email-only — and SMS-driven revenue can outpace email by Q2 of consistent operation.

03Implementation

Set up in 3 steps

  1. 01

    Wire to your SMS platform

    Klaviyo SMS, Postscript, Attentive, Yotpo SMS — all supported. The opt-in pushes to your platform with TCPA consent recorded.

  2. 02

    Make the discount phone-required

    If phone is optional, 70%+ skip it. Required phone bumps SMS opt-in to 60-80% of completers.

  3. 03

    Test the welcome SMS

    Auto-send the discount code via SMS within 30 seconds of opt-in. Test with your own phone first — delivery issues happen.

04Q & A

Frequently asked

Q1

Is SMS marketing legal in my country?

TCPA (US) requires explicit opt-in + clear disclosure + STOP keyword. The template ships with TCPA copy. Other countries (CASL Canada, PECR UK) have similar rules. Check your jurisdiction.

Q2

Should I run SMS in addition to email or instead of?

In addition. Different audiences engage on different channels. Two-channel lists outperform single-channel by 30-50%.

Q3

How often should I text?

Less than email. 1-2 texts per week max. Over-texting is the #1 reason for SMS unsubscribes — and once they unsubscribe, you can't reactivate.
