Getting Receipt confirming e mail has been read

Question

When sending an e mail I would like confirmation that it has been opened / read by the person (s) it has been sent to.
Can it be done..?
How do you set it up..?

Answer 1

I found something online which does the job very well.
PLEASE NOTE: I did not create this but I couldn't find the link to the site I found it on initially, so apologies to the original write for not giving credit.
Paste this into Script Editor and make into an application.
Double clicking on it will present you with a dialogue box asking which account you wish to use (if you have multiple accounts) and will then pop up a normal compose mail box.
For some reason if you have images attached to your signature it doesn't display them when you compose your mail but it will still send them regardless.
Obviously this is subject to the receiver having a mail client that will accept read receipts.
tell application "Mail"
set listOfSenders to {}
set everyAccount to every account
repeat with eachAccount in everyAccount
set everyEmailAddress to email addresses of eachAccount
if (everyEmailAddress is not equal to missing value) then
repeat with eachEmailAddress in everyEmailAddress
set listOfSenders to listOfSenders & {(full name of eachAccount & " <"Which account would you like to send this message from?" without multiple selections allowed
if theResult is not equal to false then
set theSender to item 1 of theResult
tell application "Mail"
set newMessage to make new outgoing message with properties {}
tell newMessage
set visible to true
set sender to theSender & "
Disposition-Notification-To: " & theSender
end tell
activate
end tell
end if
I hope this helps you out. Tested and working in 10.4.11
