Title: Newsletter Signup → Automatically Send Unique 10% Coupon Code (Odoo 19)

Hello everyone,

I would like to implement the following scenario in Odoo 19 and would appreciate advice on the best standard approach.

Scenario:

• A visitor subscribes to the website newsletter.

• Immediately after subscribing, the visitor should receive an automated email.

• The email should contain a unique 10% discount code.

• The discount code should be valid for the visitor's first purchase only.

• The campaign is only active until July 15.

My questions are:

1. Is it possible in standard Odoo 19 to automatically generate a unique coupon code for each newsletter subscriber?

2. Can Marketing Automation trigger an email directly after newsletter signup?

3. What is the best way to link a coupon code to a specific subscriber/contact?

4. Is there a standard way to restrict the coupon to the customer's first purchase only?

5. Would you recommend using Loyalty Programs, Promotions, Marketing Automation, or another approach?

6. If unique coupon generation is not available in standard Odoo, what is the recommended workaround?

I am looking for the most standard Odoo solution possible and would like to avoid custom development if feasible.

Thank you for your help.
