How soon should a win-back message go out?

As soon as the account crosses your dormant threshold. Waiting for a scheduled campaign lets the gap grow.

Why add a voice call after WhatsApp?

Some customers never reply to text. A call in their language reaches a group that messaging alone misses.

Does someone need to write a campaign brief each time?

No. Once the dormant rule and the message are set, the agent runs the loop continuously.

How to win back dormant B2B customers on WhatsApp and voice

Define a customer as dormant after a fixed gap with no order, for example 30 days. As soon as an account crosses that line, send a short, personal WhatsApp message that references what they used to order. If there is no reply, follow up with an AI voice call in the customer's language. Log the reason they stopped, hand the ones who want to talk to a person, and run the whole loop continuously instead of as a quarterly campaign.

Pick one definition of dormant

Win-back fails when nobody agrees on who is dormant. Choose one rule, such as no order in 30 days, and apply it to every account. A weekly-ordering retailer who goes quiet for a month is a very different signal from a quarterly buyer, so adjust the window per segment if order frequency varies a lot.

Reach out the day they cross the line

The longer an account stays silent, the more likely it has moved to another supplier. A quarterly campaign reaches most dormant customers weeks after they stopped. A continuous trigger reaches each one when the gap first opens.

WhatsApp first, call second

WhatsApp is cheap, asynchronous and already where the conversation lives, so it goes first
Keep the message short and specific: what they used to order, and a direct question
The customers who do not reply get an AI voice call, which reaches people who ignore text
Both use the customer's language, not a single default

Learn why they stopped

Every reply carries a reason: price, stock-outs, a delivery problem, a competitor's offer, or a shop that closed. Record it. The reasons are often worth more than the reorders, because they point at the problem that created the dormant list in the first place.
