How Clints Scaled Drop Revenue by 25.93% with WhatsApp and SMS

Clints, a fast-growing streetwear brand known for limited clothing and sneaker drops, partnered with Zefir to structure its drop communication strategy across WhatsApp and SMS.

With most of the month operating behind a password-protected store and relying heavily on organic Instagram hype, timing and exclusivity were critical.

After implementing Zefir before BFCM, Clints scaled revenue by 25.93% by turning WhatsApp and SMS into high-impact drop execution channels.

About the brand

Clints operates on a drop model:

• 1–2 limited releases per month

• Store locked behind password outside drop windows

• High demand driven by organic Instagram following

• Short, high-intensity sales windows

The brand does not rely heavily on paid acquisition.
Momentum, community, and timing drive sales.

The challenge was clear:

• How to notify core followers instantly

• How to create structured early access

• How to maximize revenue during short drop windows

• How to follow up before stock sells out

• How to control urgency without losing exclusivity

1. Structured early-access drop strategy

Before implementing Zefir, drop communication relied mainly on Instagram posts and stories.

With Zefir, Clints implemented:

• Early access WhatsApp campaigns

• Timed SMS reminders

• Last-hour follow-ups

• Segmented access for core supporters

This allowed the team to:

• Open drops early for selected customers

• Trigger urgency messaging in real time

• Send final reminders before password removal

• Capture attention instantly during high-traffic windows

During drops, WhatsApp campaigns achieved:

• Up to 97% open rates

• High click-through engagement

• Fast sell-through velocity

Instead of relying solely on algorithm-driven reach, Clints communicated directly with high-intent buyers.

2. BFCM execution and revenue acceleration

Ahead of Black Friday and Cyber Monday, Clints structured their messaging calendar using Zefir.

They executed:

• Controlled early access windows

• Time-sensitive promotional campaigns

• SMS reminders during peak hours

• Coordinated WhatsApp + SMS sequencing

Because drops operate on short attention windows, immediate visibility was essential.

The result:

• 25.93% increase in revenue

• Faster sell-outs during drop windows

• Higher engagement compared to Instagram-only announcements

• Clear attribution of messaging-driven sales

3. Christmas £5,000 giveaway campaign

Clints also used Zefir to execute a high-engagement Christmas campaign:

A £5,000 cash prize was hidden inside a shoe drop.

The campaign was announced and driven via:

• WhatsApp broadcasts

• SMS reminders

• Drop countdown messages

This created:

• Increased anticipation

• Higher participation rates

• Expanded subscriber list growth

• Strong brand engagement

Instead of relying on social-only hype, Clints activated its direct messaging audience to amplify campaign reach.

4. Measurable business impact

By structuring drop communication through Zefir, Clints achieved:

• +25.93% revenue growth

• Up to 97% WhatsApp open rates during drops

• Faster inventory sell-through

• Increased drop participation

• Higher engagement vs Instagram-only communication

WhatsApp and SMS became controlled access tools — not just promotional channels.
