Parameters let you turn a generic template into a personalized message. Instead of sending the same text to everyone, you can adapt parts of the message with specific data such as name, order, or date.

​
What are parameters?

They are placeholders within the template that are automatically filled with dynamic information. They are written in double curly braces with a number: {{1}}, {{2}}, {{3}} They can represent:
  • Customer name
  • Order number
  • Date
  • City
  • Any relevant data for the message

​
Example

Template: Hello {{1}}, your order {{2}} has been shipped and will arrive on {{3}}. Final message received: Hello Ana, your order 5678 has been shipped and will arrive on April 21. The same message can be automatically adapted for each recipient.

​
How to use parameters in Jelou

To correctly configure a template with parameters:
  1. Write the message text.
  2. Insert parameters using double curly braces and numbers: {{1}}, {{2}}, {{3}}
  3. Make sure the order and quantity match exactly with the data you will send.
If the order or quantity do not match, the template may fail or be rejected.

​
Where do the values come from?

When you send a campaign, the values come from:

​
CSV file

  • The first column must be the phone number (with country code).
  • The following columns must correspond to the parameters.
  • Each row represents a recipient.

​
Configuration within Jelou

When creating the campaign, you map each parameter to a column in the CSV file. Jelou automatically replaces the values in the final message.
The CSV must have the same number of parameters as the template.

​
Best practices

Keep the message clear and focused. ✔️ Recommended example: Hello {{1}}, your appointment is on {{2}} at {{3}}. ❌ Unclear example: {{1}}, your info: {{2}}, {{3}}, {{4}}, {{5}}. Additionally:
  • Do not use consecutive parameters without intermediate text.
  • Avoid leaving fields empty.
  • Always test before sending.

​
How many parameters can you use?

You can use up to 9 parameters per message. But more does not mean better. The key is to use them with intention. ✔️ Correct example: Hello {{1}}! This is your ticket number: {{2}}.
Your flight to {{3}} is scheduled for {{4}} at {{5}}. Have a great trip! ❌ Incorrect example: {{1}}, here is information about your ticket: {{2}}.
{{3}} {{4}} {{5}} Clarity is always the priority.

​
What happens if a parameter is empty?

If a parameter has no value:
  • The message may come out incomplete.
  • It may look unprofessional.
  • It may affect the user experience.
That is why it is important to validate before sending.

​
How to test your parameters

Before launching a campaign:
  • Use the preview in Jelou.
  • Send yourself a test message.
  • Verify that all values are replaced correctly.
  • Fix any errors before the bulk send.
Personalizing your messages well improves the experience and increases the likelihood of a response. The key is not to use more parameters, but to use them with intention.
