I would like to suggest an enhancement to Shopware 6 that brings back a popular and valuable feature from Shopware 5: automatically sending birthday emails with discount codes or greetings to customers.

The Issue:
Currently, Shopware 6 lacks the functionality to automate birthday-related actions through the Rule Builder and Flow Builder. This prevents shop owners from creating personalized birthday campaigns, which are an effective tool for customer engagement and loyalty.

Proposed Solution:
Enhance the Rule Builder and Flow Builder with the ability to:

Identify Birthdays:

Add a rule condition that checks the "Date of Birth" field in customer profiles.
Allow dynamic filtering, such as "is today," "is in the next X days," or "has already occurred this year."
Automated Email Trigger:

Enable automated email workflows based on the customer's birthday, either on the exact date or as part of a pre-scheduled campaign.
Custom Discount Code Generation:

Integrate the ability to generate unique, single-use discount codes as part of the workflow.
Include these codes dynamically in the email template.
Personalized Messaging:

Allow email templates to include dynamic fields, such as the customer's name or age (optional), to make the greetings feel personal.
Benefits for Shop Owners:

Strengthened Customer Loyalty: Birthday emails are a great way to engage customers on a personal level and show appreciation.
Increased Sales Opportunities: Discounts incentivize customers to make a purchase, driving revenue.
Time Efficiency: Automating this process saves time for shop owners, especially for shops with a large customer base.
Customer Delight: A thoughtful gesture like a birthday greeting can leave a lasting positive impression.
