Abandoned cart SMS for WooCommerce: a recovery guide

7 out of 10 customers fill their cart and leave without buying. See how to bring them back with automatic SMS & Viber: step by step, legally and cost-effectively.

Cart abandonment is the biggest "invisible" lost revenue of every online store. According to the Baymard Institute, the average abandonment rate reaches ~70%. The good news: a timely, well-written abandoned cart SMS can recover part of those sales automatically.

What is an abandoned cart?

It is the cart of a visitor who added products but did not complete the order. The reasons vary: unexpected shipping costs, mandatory registration, a slow checkout or simple procrastination. Cart recovery sends a targeted reminder that restores the cart with a single click.

Why SMS and not just email?

  • Open rate of ~98% versus ~20% for email: the message actually gets read.
  • Immediacy: it arrives within minutes, while the interest is still warm.
  • Complementary: it works perfectly alongside email recovery, not instead of it.

With iSend, abandoned cart recovery runs natively inside WooCommerce through the plugin. See the full Abandoned Carts feature.

How recovery works, step by step

  1. Capture: the plugin records the cart (products, total, unique recovery link).
  2. Consent: the customer provides a phone number and consent at checkout (ideally with OTP verification).
  3. Detection: after a set period (e.g. 30 minutes) the cart is considered abandoned.
  4. Sending: an SMS/Viber message goes out automatically with the recovery link and (optionally) a discount code.
  5. Recovery: the customer taps the link, the cart is restored and the purchase is completed.

Best practices

  • Timing: 1st reminder after ~30-60 minutes, 2nd after ~24 hours. Do not overdo it.
  • Incentive: a small coupon (e.g. -10%) significantly increases conversions.
  • Clear CTA: "Complete your purchase" plus the recovery link.
  • Hours: respect quiet hours.
  • GDPR: send only to those who have given consent and offer an opt-out.

How much can you recover?

As an example, an online store with 200 orders/month and an average order value of 45€ has roughly 467 abandoned carts/month. Even with a conservative 10% recovery rate, that is ~2,100€/month in additional revenue. These numbers are indicative; actual results depend on your industry and your offer.

Conclusion

The abandoned cart SMS is one of the most cost-effective automated messages an online store can set up: low cost, a high open rate and a direct impact on revenue. With iSend's WooCommerce plugin you can enable it in minutes.
