The WhatsApp Abandoned-Cart Recovery Playbook (Timing, Tone, Templates)

Abandoned-cart email has been in freefall for five years. Open rates hover around 20%, click-through around 3%, and recovered-cart conversion near 2%. WhatsApp does 15% on the same cohort. The gap isn't magic — it's attention.

The winning sequence is three messages over 24 hours:

• T+30 min: "Hi [name], looks like you left [item] in your cart. Still want it?" Soft, single-image template, direct link back. This alone recovers 60% of the eventual recoveries.

• T+4 hours: size/variant reminder with delivery date. Adds urgency without a discount. Converts another 25%.

• T+24 hours: final nudge with a small, time-bounded incentive (free shipping, 5% off). Converts the remaining 15%.

Three rules that determine whether this works:

1. Use Meta-approved marketing templates — not session messages. You lose 70% of recoveries if you wait for a session window.
2. Send at local-commerce-friendly hours (9am–9pm local). Send a reminder at 2am and you'll get marked as spam, then your quality rating falls, then your delivery rate falls.
3. Respect opt-out. One STOP reply, full suppression, forever. Meta audits this, and violations tank your phone number's rating within weeks.

NimbleBiz ships this sequence as a prebuilt template with Shopify, WooCommerce, and custom-webhook triggers. Turn it on, map your product catalog, and the first recovered cart usually lands within 45 minutes.
