What does nsfw mean on returned mail

A common question!

"NSFW" is an abbreviation that stands for "Not Safe For Work." It's often used to indicate that the content of an email, attachment, or link is not suitable for a work environment due to its explicit or mature nature.

In the context of returned mail, "NSFW" is usually used to alert the sender that the email or attachment they sent was rejected or bounced back because it contained content that is not appropriate for a work setting. This might include:

  1. Explicit images or videos
  2. Mature or adult content
  3. Graphic violence or gore
  4. Strong language or profanity
  5. Other types of content that are considered offensive or inappropriate

When you see "NSFW" on returned mail, it's likely that the email or attachment was flagged by the recipient's email provider or their organization's IT department as containing content that is not suitable for a work environment. This is usually done to protect employees from potentially offensive or disturbing content and to maintain a professional work environment.

If you receive an email with "NSFW" on returned mail, it's likely that the sender intended to share something inappropriate or explicit, and you may want to contact them to clarify what they meant to send or to ask them to re-send the content in a more appropriate format.
