I need a small, fuss-free utility that produces 10 – 50 valid email addresses with truly random usernames. Don’t worry about marketing, transactional, or newsletter formatting—I only care about the address itself. Here’s the flow: I’ll hand you a text file containing seed words that you can shuffle, splice, or combine however you like. Your code (Python, JavaScript, Bash, or anything lightweight) should turn those seeds into unique usernames, append a placeholder domain such as @example.com, and hand the results back to me in a single CSV or TXT file. Acceptance check • Exactly the quantity requested (I’ll confirm the final count before you run). • No duplicate usernames. • Each address is RFC-compliant: lowercase letters, numbers, optional dots or underscores are fine—just nothing that breaks standard email rules. Turnaround can be same-day if possible; the script should be easy for me to rerun whenever I need new batches.
