How do I customize an email in shopify flow by putting customers first name

Topic summary

Issue: How to insert a customer’s first name into a Shopify Flow email template and what happens if the name is missing. The poster currently uses {{ customer.first_name }} and asks if this is correct.

Guidance: Don’t guess variable names. Use the “Add a variable” link available below fields that accept variables to insert the correct token and see its exact name.

Details: Variables are typically camelCase (e.g., firstName) rather than using underscores. The exact token should be selected from the variable picker to avoid syntax errors.

Status: Partial guidance provided (how to find and format the correct variable). The question about behavior when the customer name is absent (e.g., blank output or fallback) remains unanswered, and no final resolution or action beyond using the variable picker was confirmed.
