When to Use SMS Marketing

• Flash sales — "24-hour sale: 30% off everything. Shop now: [link]"
• Abandoned cart recovery — Complement email with an SMS touchpoint
• Order and shipping updates — High satisfaction, builds trust
• Appointment reminders — Reduces no-shows dramatically
• Exclusive subscriber offers — Make SMS subscribers feel valued

When NOT to Use SMS

• Sending more than 2–4 times per month without strong purpose
• Non-urgent informational content (use email instead)
• Long-form content (not suited to the format)
• Cold outreach (must have explicit consent)

SMS Compliance (GDPR)

Explicit opt-in is mandatory. Clear disclosure of message frequency, easy opt-out mechanism ("Reply STOP to unsubscribe"), and never use purchased lists.

Best Practices for SMS Copy

• Under 160 characters to avoid message splitting
• Lead with the offer or value
• Include a shortened, trackable link
• Include brand name (sender ID)
• Clear CTA
