Why Email Templates Are Essential for Debt Collection in 2026

In 2026, late payments plague businesses: 68% of companies receiving over half their payments past due face cash flow crises (HighRadius). Over half of B2B invoices go overdue (Quo), with average Days Sales Outstanding (DSO) at 67 days. Recovery rates plummet after 90 days (SW Recovery).

Email shines in accounts receivable (AR) management--69% of agencies use it (TCN), outpacing SMS at 40%. A PDCflow validation campaign boosted response rates by fine-tuning templates, proving emails recover debts faster than letters alone (98% still rely on mail, per TCN).

Emails enable personalization, tracking, and automation, turning overdue chaos into steady cash flow.
