Why Retention Beats Acquisition
Attracting a new customer costs on average 5 times more than bringing back an existing one. Yet most food truckers put 90% of their marketing energy into acquisition: Instagram, flyers, word of mouth. Retention stays the neglected side.
A loyal customer means:
- Higher purchase frequency (2 to 4 times a month versus once for a new customer)
- Often a higher average order (they know your menu and order without hesitation)
- A natural ambassador who tells friends and colleagues
Step 1: Build Your Contact List
Nothing is possible without contacts. And no, your Instagram followers don't count — you don't own them on those platforms, the algorithm decides.
How to Collect Contacts at the Truck
A QR code on the counter is the most effective method. It links to an ultra-short form: first name + email or phone number. Nothing more. Each additional field halves the conversion rate.
An incentive to sign up seals the deal. Offer something useful:
- "Get my weekly schedule every Monday"
- "Sign up for a free drink on your next visit"
- "Early access to my new dishes of the month"
What GDPR Says
Collecting personal data means explicit consent is mandatory. A checkbox (not pre-ticked) is enough. State clearly: "By signing up, you agree to receive our news by email. Unsubscribe at any time." An unsubscribe link must appear in every email you send.
Step 2: Choose Your Tools
No need to invest in complex solutions.
For Email
Mailchimp (free up to 500 contacts) remains the most accessible to start. Simple interface, ready-made templates, clear stats.
Brevo (formerly Sendinblue) is an interesting French alternative if you want to manage email and SMS from one place. The free plan allows 300 emails per day and includes SMS sending in France.
For SMS
SMS costs between €0.05 and €0.12 per unit depending on the provider. For a food truck with 200 active contacts, one SMS campaign costs €10–€25. For that price, you potentially reach 190 people (95% open rate).
Octopush and SMSMODE are two reliable French providers with per-unit pricing and no monthly commitment — ideal for getting started.
Step 3: What to Send (and When)
The Weekly Schedule — Your Most Useful Content
Every Monday morning, send an email or SMS with:
- Your locations for the week (days, hours, addresses)
- The dish of the day or this week's new item
- A link to your Instagram if you post live stories
The Flash Promo — to Fill a Quiet Service
You have a slow Tuesday morning and fresh stock to move? Send an SMS at 9am:
"Hi, we're at the Halles market today until 2pm. 20% off the daily menu for the first 20 orders — show this SMS."
SMS is the perfect tool for this because the average time between send and read is under 3 minutes.
The Monthly Newsletter — to Build a Relationship
Once a month, a longer email (300 to 500 words) to:
- Share a recipe or behind-the-scenes story about a dish
- Announce a seasonal menu change
- Thank your regulars (with an exclusive offer)
Step 4: Segment to Target Better
Once your list goes past 100 contacts, segment. Two groups are enough to start:
Regular customers (3 or more visits): deserve exclusive offers, early access, more personal communication.
Occasional customers (1 or 2 visits): need reactivating. Send them an SMS: "we haven't seen you in a while — here's a reason to come back" with an offer.
Your POS software (SumUp, Lightspeed...) can help identify these two groups if you maintain a customer database.
Step 5: Measure and Adjust
Three metrics to track each month:
Email open rate: below 25%, either your subject line is not compelling enough or you're sending too often.
Unsubscribe rate: above 2% per send, the content is off or the frequency is too high.
Return rate: how many customers who received your email came back within 7 days? Hard to measure without a dedicated tool, but a unique promo code per campaign gives a reliable indication.
The Most Common Mistakes
Sending too often. One SMS per week is too much. Two per month maximum, and only when you have something useful to say.
Neglecting the email subject line. 50% of your open rate depends on the subject. Be specific and direct: "Your food truck schedule this week" beats "Our March news" every time.
Sending the same message to the entire list. A customer who comes every Friday doesn't need to be told where to find you — they already know. Speak to them differently.
Forgetting mobile. 80% of your emails are read on a smartphone. Always test your layout on mobile before sending.

Frequently Asked Questions
- How do I collect my food truck customers' emails and phone numbers?
- The simplest method is a QR code displayed on your counter or packaging that links to a short sign-up form (first name + email or phone). You can also offer an immediate reward: a free drink on the next visit, or early access to your weekly schedule. Avoid paper forms: data is hard to use and GDPR applies to digital formats too.
- How often should I send emails and SMS for my food truck?
- For emails, once a week is a good rhythm: weekly schedule on Monday, recipe or behind-the-scenes on Wednesday, or a Friday deal. For SMS, limit yourself to a maximum of 2 sends per month — an unwanted text drives unsubscribes faster than almost any other mistake. The key is value: every message should offer something useful (location, deal, new item).
- What free tool can I use to send emails to my food truck customers?
- Mailchimp is often the first choice: free up to 500 contacts and 1,000 emails per month, with simple templates. Brevo (formerly Sendinblue) offers a free plan including SMS in France, making it a strong option for food truckers who want to manage both email and SMS from one tool. For SMS only, Octopush or SMSMODE are French providers with per-unit pricing and no subscription.
- Does GDPR apply to a food truck's email list?
- Yes. As soon as you collect personal data (email, phone number), GDPR applies even if you are a sole trader. You must obtain explicit consent (opt-in checkbox, not pre-checked), state the purpose of collection, and include an unsubscribe link in every message. CNIL fines can reach €20 million for large companies, but in practice for a food truck the real stakes are customer trust.
- How do I measure whether my food truck email strategy is working?
- Track three simple metrics: open rate (aim for 30% minimum for an engaged list), click-through rate on your links (aim for 5%+), and above all the return rate — how many customers who received your email came back within 7 days? That last metric is the hardest to measure but the most useful. A unique promo code per campaign helps you track conversions.
