A high-ROI WhatsApp strategy for the sales is built around 4 key moments:

1. Building your audience & teasing

Goal: lay the groundwork

Collect and qualify your WhatsApp opt-ins
Tease the exclusive perks (early access, VIP offers, best-sellers on sale)

This is the key phase to build an engaged audience before the rush.

Make the most of email-to-WhatsApp to grow your audience for free
Use rich formats such as video and voice messages to tease upcoming offers and build anticipation.
Remember to tag your opt-ins properly with the "Opt-in" node in WAX so they're correctly added to your retargeting contact list.

Goal: generate an immediate sales peak

Announce the start of the sales in real time
Highlight your key offers and categories
Play on exclusivity and urgency

WhatsApp is ideal for grabbing attention in the very first hours, with an average open rate of 90%.

Stress that the offer is exclusive to WhatsApp: some brands increase the impact with an extra perk (additional discount, free shipping or a gift above a minimum purchase).
Write a punchy message: put the discount in the first lines and don't hesitate to use bold to grab attention immediately.
Include 3 complementary CTAs:
- 1 CTA redirecting to your website,
- 1 Quick Reply CTA "Inspire me", leading to another WhatsApp message showcasing a selection of sale items to move the prospect further down the funnel,
- 1 unsubscribe CTA, to follow best practices and protect the user experience.

Goal: keep up the sales momentum and maximize customer value

Highly targeted follow-ups based on behavior:
- clicked without buying
- buyers likely to purchase again
- non-buyers
Highlight new offers, successive markdowns and secondary categories
Personalize your messages to avoid fatigue

Here, WhatsApp becomes a real lever for repeat purchases, upsell and loyalty.

Stand out with fun, engaging formats: videos, reverse auctions, flash sales…
To boost your flash sales during the promotion period, use the Limited Time Offer template to increase the sense of urgency.
Exclude buyers who have already converted since the start of the sales from your segment, to focus on prospects who are still active.

Goal: capture last-minute sales

High-urgency messages: "Final hours", "Last items available", "Sales end tonight"
Focus on the best remaining deals and limited stock

FOMO is a powerful decision accelerator, especially effective on an instant channel like WhatsApp.

Use the Limited Time Offer template to increase the sense of urgency.
Highlight your best-sellers to capitalize on your top-performing products.
Sub-segment your audience to retarget customers based on the product categories they viewed on your website.
