Debtor Engagement
SMS, Email, WhatsApp or Calls: Which Debt Collection Channel Works Best?
Each channel is good at something different. A practical comparison and a sequencing approach that works in South African portfolios.
The channel debate is usually settled by habit rather than evidence. A more useful framing: what is each channel actually good at, and where in the sequence does it belong?
SMS
Good at: reach, immediacy, low cost, reminders. Weak at: nuance, negotiation, longer explanations. Best used for pre-due arrangement reminders and short prompts with a payment link.
Good at: two-way conversation at low cost, document and reference sharing, asynchronous engagement with debtors who cannot take calls at work. Weak at: establishing verified identity, and it requires disciplined record keeping so the exchange lands on the file.
Good at: detail, statements, formal correspondence and evidence. Weak at: urgency and consumer reach where addresses are stale.
Voice
Good at: negotiation, affordability conversations, dispute resolution, complex arrangements. Weak at: cost per contact and scale. Reserve it for accounts where a conversation genuinely changes the outcome.
