2. New Senders Can Trigger Spam Filters

If you've never received mail from someone before, email providers may be more cautious.

✔️ Try This:

Check your Spam or Junk folder regularly when expecting an important message.


3. Attachments Can Affect Filtering

sometimes receive additional scrutiny.

This is especially true if the sender is unfamiliar.

Gmail
