Re-establish a Clear Value Proposition:
Why should they opt-in (again)? You need a compelling reason for people to trust you with their number after a past negative experience.
Focus on Exclusivity: Emphasize benefits they can't get elsewhere (e.g., "VIP deals," "early access," "private tips").
Be Specific: Clearly state what kind of messages, how often, and the immediate benefit.
Prioritize Compliant & Transparent Opt-in Methods:
Double Opt-in is Non-Negotiable: Make it standard for all new south africa phone number list sign-ups. This is your strongest defense against future compliance issues and ensures high-quality leads.
Prominent Website Forms: Redesign pop-ups and embedded forms to be compliant, user-friendly, and value-driven.
Keyword Opt-in: Promote a new, fresh keyword if the old one was associated with negative experiences. Ensure all disclosures are on signage, digital ads, etc.
Checkout Opt-in (E-commerce): Review this process to ensure the SMS opt-in is a separate, unchecked box.
Consider a "Re-Permission" Campaign (If Legally Viable):
For Existing (Potentially Damaged) Contacts: If your previous list had consent issues but you don't want to completely lose everyone, you might send a single, very clear SMS asking them to re-opt-in.
Caveat: This is a delicate legal area. Consult legal counsel. If the initial opt-in was highly problematic, even this single message could be risky. It's often safer to treat them as new leads.
Message Example: "Hi [Name], we're updating our SMS program to ensure you only get texts you love. If you still want [exclusive deals/updates], reply YES to confirm. Text STOP to opt-out. Thanks!"
