Remove entries that lack an "@" symbol or have invalid extensions (e.g., .con instead of .com ). 2. List Segmentation

Sending emails to a 150k list without verification will likely get your IP blacklisted. Never store large access lists in plain text

Ensure the list follows a standard email:password or email,name format.
