Is it possible to receive a email from someone without them knowing it was received by the recipient?

so they don't know I opened it?

1. no clue how many emails I send are viewed. one supposes there are ways to track email read rates however. nt

2. Yes

But this MAY be under the control of the sender.

I use Thunderbird; in my server settings, under Return Receipts I have selected 'Never Send a Return Receipt'. I can't speak for other email clients or web IMAP emails such as Gmail.

3. hotmail?

4. You'll have to

Trawl through the settings to see what's on offer. I don't use hotmail.

Look for 'return receipts', 'read notifications' or similar. You may find it.
