Flash sales fail when they're announced on channels that take hours to open.

01

You run a 6-hour flash sale and send the announcement via email. 20% of your list opens it — half after the sale is already over. The urgency that drives flash sales is completely undermined by slow channel open rates.

02

Social media posts reach a fraction of your followers. Instagram organic reach for branded accounts is under 5%. You're shouting into a room where most of the seats are empty.

03

Your marketing team has no reliable way to reach your entire opted-in customer base instantly. That's a gap that costs you every time-sensitive campaign you run.

The solution

WhatsPortal delivers your flash sale to your entire opted-in list on WhatsApp — in minutes.

Instant bulk broadcast

Upload your contact list or sync from your CRM. Hit send and your flash sale announcement reaches thousands of opted-in customers simultaneously — no throttling, no delays.

Scheduled broadcasts

Set your flash sale announcement to go out at a specific time — 9 AM on Saturday, the moment your sale goes live — so your marketing team isn't manually sending at 3 AM.
