Mozilla Thunderbird Email

[derekpara]

Having just installed Windows 10 I am now using Thundebird as my email provider instead of Windows Live Mail. I quite like it but can't find a link which lets me know that a 'sent' message has been opened. Any help appreciated.

Cheers.

Unsure and can't check, but just to say that over the public internet the receiver need not send any confirmation. It's private work networks that are usually set up to ensure it happens.

When your 'composing' your email, go to Options and select 'Return Receipt'.
However as OG says it is optional on the part of the receiver to agree to send a 'Read Receipt'. I don't send read receipts.
Mainly used in offices/companys.

Since recipients of your emails can open them 'locally' (e.g. after downloading them to an email client and them opening them while offline) you can never be sure whether or not a recipient has actually opened your mail. The best you can do is to send a request for a 'read receipt':

You need to request a receipt, which you can do when you compose the email (options/return receipt). But as OG says most people configure their email clients to ignore such requests, so while receiving one will indicate that the email has been opened, not receiving one indicates nothing at all. You can configure how your own copy of TB responds (or not) to such requests by going to Tools/Options/Advanced Return Receipts. By default this is (I believe) set to "never send a return receipt".

Thanks to you all. Fully understand now.
