You can get delivery confirmation with email as well. There are several ways to go about it.
You can send a receipt request but that relies on the receiver to acknowledge it and their system may not recognize the request.
Another, probably better way, is to send it with a delivery status notification which is a request to the recipient's email server to send you a notification about the delivery of an email you've just sent.That's set up in your email account settings, not when you send the email.Your email is probably already set up to always make the request but only when an email is bounced. That aspect can be changed to alert you with correct deliveries, delays & etc.

Thunderbird has, in the Options menu, check boxes for Return Receipt and Delivery Status Notification which would override the default account settings.

Then, you can insert a include a tiny transparent image (tracking bug or web beacon) in your email body. When your email contact reads the email message, his/her email program will attempt to download the nested image. The confirmation can then be checked as long as you have access to the particular email server. That would mean you'd have to use your own website email system such as joe@joeblow.com. For online email such as outlook, inbox & etc you'd likely have to use a third party tracking program.

Of course, every important email should be CC'd or BCC'd back to yourself. For something as important as what Jim had sent out I would have CC'd myself and anyone else involved so the receiver would know and that would, in most cases, move them to open and read the email.
