Watch out for

Generic prompts can lead to repetitive responses so include dynamic variables for each applicant's unique details in the template.
SMTP servers may reject bulk emails if you send too many replies quickly so add a delay node between sends to respect rate limits.
The parser might fail if the LLM returns malformed JSON so implement error handling to retry or log failed generations.
Privacy regulations require careful data handling so ensure you do not store sensitive applicant PII in your workflow logs.
