The Sallys Welt Story

Sallys Welt is Germany's largest cooking and baking channel on YouTube. Founded by Saliha "Sally" Özcan, who uploaded her first baking video in 2012. Today the brand has over 2.2 million YouTube subscribers, more than one million Instagram followers, around 150 employees, and its own online shop with over 1,000 sales per day. From baking accessories to Damascus knives to kitchen machines. During Black Week, e-commerce brands like Sallys Shop face a clear challenge. Inboxes explode, discounts blur together, and customer attention is split across hundreds of offers at once. Sallys Welt needed a channel that feels more personal than email and reaches their loyal community where they actually read. They chose WhatsApp with Chatarmin. A channel that fits the brand. Sally speaks to her community personally.

Customer Experience

Here's how the campaign was built.

Sallys Welt ran a WhatsApp campaign via Chatarmin during Black Week that was perfectly tailored to their audience. The campaign promoted the Damascus Knife Super Sale with a clear, time-limited offer. The message opened with a product image and the price: "Today only: Sally's Damascus Knife for an unbeatable €79.99." Followed by a personalised first-name greeting: "Hey Richard, this deal has never happened before!" Then the details: five Damascus knife models, all reduced from up to €149.99 down to €79.99. Perfectly balanced, extremely sharp, and handcrafted. And clearly stated: "This deal is valid today only (14.11.) and only while stocks last!"

Campaign1 As a bonus, the message pointed to the ongoing Black Sale deals on kitchen essentials with up to 50% off. At the end, a green button: "TO SALLY'S DAMASCUS KNIVES." One clear goal, one click, straight to the shop.

Campaign2 The combination of a time limit, personal address, and a product the Sally community knows and loves drove the conversion. Anyone familiar with Sally's Damascus knives knows what they cost. €79.99 instead of €149.99 is an offer that motivates immediate action.

The WhatsApp strategy

Product-focused campaigns

Product-focused campaigns

Sallys Welt built the Black Week campaign around one specific product: Damascus knives for €79.99 instead of up to €149.99. A clearly defined offer works better on WhatsApp than a generic "everything is on sale" newsletter. Recipients know immediately what they're getting and what it costs.

Personalised messaging

Personalised messaging

Every message started with the recipient's first name. "Hey Richard, this deal has never happened before!" That creates immediate attention and separates the message from the hundred other Black Friday emails in the inbox.

Scarcity and time limits

Scarcity and time limits

"This deal is valid today only (14.11.) and only while stocks last!" That creates real urgency. With an open rate of 83.8%, the message gets read before the offer is gone. Email simply cannot deliver that kind of time pressure.

Relevant content instead of mass communication

Relevant content instead of mass communication

Sally's community trusts the brand and knows the Damascus knives from the YouTube videos. The campaign plays directly into that. Anyone who knows Sally's knives understands the value. €79.99 instead of €149.99 is an offer that motivates immediate action.

Your unfair advantage over email

Talk to your customers, not at them

Talk to your customers, not at them

The Sally community is one of the most engaged in German-speaking e-commerce. WhatsApp makes the connection between brand and fans even more personal. Customers reply, ask for recipes, recommend products to others. This is a conversation on equal terms.
