Consent is Paramount: This is the most crucial step. Always obtain explicit, verifiable consent for marketing messages.
Website Forms:
Dedicated Pop-ups/Forms: Create mobile-responsive pop-ups (exit-intent, timed) or embedded forms offering a clear incentive (e.g., "Text JOIN for 10% off your first order!").
Checkout Opt-in (E-commerce): Offer a separate, unchecked box at checkout for SMS marketing consent.
Keyword Opt-in:
Text-to-Join: Promote a keyword (e.g., "TEXT STARTUP to 12345") on your website, social media, print materials, or in-store.
Disclosures: Ensure all promotions clearly state: what messages south africa phone number list they'll receive, frequency, "Msg & Data Rates May Apply," and how to opt-out ("Text STOP to unsubscribe").
Social Media: Run contests or promotions where opting into your SMS list is a requirement (again, with explicit consent).
Double Opt-in (Recommended): Send a confirmation SMS after initial sign-up asking users to reply "YES" to confirm. This creates a high-quality list and provides undeniable proof of consent.
Step 4: Segment Your Mobile List
Start Simple: As a startup, you might begin with broad segments (e.g., "new sign-ups," "first-time buyers," "beta users").
Layer Data: As you grow, integrate data from your CRM or e-commerce platform to create more granular segments based on:
Purchase history
Website behavior (e.g., viewed specific product category)
Demographics (if collected during opt-in)
Engagement levels
