What to Look For

  • Incorrect email address in the "From" field

  • No subject or one with special characters

  • Inclusion of emojis or non-standard characters

Fix the Problem

  1. Correct the Email Format: Use a format like [email protected].

  2. Check the Subject Line: Avoid blanks and stick with simple characters.

  3. Use Standard ASCII Text: Remove emojis and symbols.
