Why Generic Food Promotions Are Becoming Less Effective

The food delivery ecosystem in Spain has become dramatically more competitive. Customers in Barcelona, Lleida, Tarragona, and Girona are exposed daily to promotions from restaurants, cloud kitchens, and delivery platforms. Because of this saturation, generic discounts are losing effectiveness. A restaurant sending "20% OFF on all menu items today" may actually perform worse than a smaller, highly targeted offer such as "Your favourite paella is back. Order before 8 PM and get free tapas." The second message feels relevant. And relevance is increasingly becoming the most important metric in conversational marketing.

What Customers Actually Mean When They Say "Personalised"

Many businesses misunderstand personalisation. Personalisation is not simply inserting the customer's first name. This: "Hi Maria, get 15% OFF today" is technically personalised, but it is not meaningful. Real personalisation happens when communication reflects customer behaviour. For example: a customer who frequently orders vegetarian dishes should receive offers for new plant-based options, not a meat lover's special. Someone who orders every Friday night might appreciate a reminder campaign. A customer who stops ordering for 45 days might need a win-back discount. This kind of targeting feels significantly more relevant, and relevance drives action.

Why WhatsApp Is Particularly Powerful for Food Businesses

Food purchases are often impulse-driven. Customers rarely spend days researching what they want for dinner. The decision window is short. This makes communication timing extremely important. For restaurants and food brands in Catalonia, WhatsApp creates a major advantage. Customers already use WhatsApp throughout the day, meaning restaurants can reach people inside a platform where attention already exists. The challenge is not reaching customers; the challenge is sending messages that feel relevant enough to open.

The Three Types of Customer Preference Data Most Restaurants Ignore

Many food businesses think they lack customer data. Usually, they already have it. They simply are not organising it properly.

1. Product Preference Data
What does the customer repeatedly order? Examples include: tapas, paella, fideuà, grilled vegetables, or crema catalana. Repeated orders reveal preference patterns surprisingly quickly.

2. Ordering Time Preferences
Some customers consistently order for office lunch, evening snacks, or late-night dinners. Sending offers at the right time dramatically increases conversion rates.

3. Spending Behaviour
High-value customers may respond better to exclusive VIP loyalty rewards, while budget-conscious customers might prefer discount-based offers. Segmenting by average order value helps tailor the message.

How to Collect and Organise Customer Preferences (GDPR-Compliant)

Under European regulations such as GDPR and LOPDGDD, you must obtain explicit consent before sending marketing messages. Here are practical ways to collect preference data legally:

• Use order forms that include optional preference fields (e.g., favourite cuisine, dietary restrictions).
• Implement a preference centre on your website where customers can select their interests.
• Track purchase history from your POS or e-commerce platform (e.g., PrestaShop or WooCommerce).
• Ask customers directly via WhatsApp surveys after an order, offering a small discount as incentive.

Store this data securely and ensure customers can easily update or delete their preferences at any time. Compliance builds trust, and trust increases engagement.

Creating Personalised WhatsApp Campaigns Step by Step

Step 1: Segment Your Audience
Divide your customer list into segments based on behaviour: vegetarian vs. meat lovers, lunch vs. dinner customers, frequent vs. occasional buyers, high spenders vs. budget shoppers.

Step 2: Craft Relevant Offers
For each segment, create an offer that matches their preferences. For example: "Your favourite vegetable paella is back with a free drink this weekend."

Step 3: Use Automation Tools
Platforms like WhatsApp Business API allow you to send personalised messages at scale. Integrate with your CRM or e-commerce system to trigger messages based on specific actions (e.g., abandoned cart, 30-day inactivity).

Step 4: Test and Optimise
Send A/B tests with different subject lines, images, or call-to-action buttons. Measure open rates, click-through rates, and conversion rates. Refine your segments over time.

Real Example: A Restaurant in Lleida Boosts Repeat Orders by 40%

A mid-sized restaurant in Lleida started collecting customer preferences through a simple form on their website. They segmented their list into three groups: lunch regulars, dinner customers, and dessert lovers. For each group, they sent weekly personalised offers via WhatsApp. Within two months, repeat orders increased by 40%, and the unsubscribe rate dropped to under 2%. The key was relevance: customers felt the restaurant understood their tastes.

Measuring Success: Key Metrics to Track

To know if your personalised WhatsApp campaigns are working, monitor these metrics:

• Open rate – ideally above 70% for personalised messages.
• Click-through rate – aim for 15-25%.
• Conversion rate – percentage of recipients who place an order.
• Unsubscribe rate – keep below 5%.
• Repeat order rate – measure how many customers order again within 30 days.

Use tools like Google Analytics or your e-commerce platform to track these numbers. Adjust your strategy based on data, not intuition.

Common Mistakes to Avoid

Even with good intentions, mistakes happen. Avoid these pitfalls:

• Sending too frequently – respect your customers' inbox.
• Using only first names without behavioural data – that's not real personalisation.
• Ignoring GDPR – always include an opt-out link.
• Not testing different messages – what works for one segment may fail for another.
• Forgetting mobile optimisation – most WhatsApp messages are read on phones.
