nope, hangt af van de ontvangen persoon.
Email confirmation for read and delivery
=> mss dit dan:
sing read receipts as email confirmations
The "request read receipt" feature is a standard feature of most email client programs. However, just as in the case of the email delivery confirmation feature, the read receipt email confirmation assumes the user who received the email must agree to send you a read receipt.
There are 3rd party services that aim to achieve the same goal (getting email read confirmations to you) and one of the most popular of them is ReadNotify. However, please note that such solutions rely on inserting scripts in the email content to be delivered to your contact. Most up-to-date email programs will trigger alerts about unsafe content being included in your email. So think twice before using such solutions, as they may harm your image, especially in a business environment.
Other email read confirmation methods
One of the most efficient "do-it-yourself" email confirmation solution is to include a tiny transparent image in your email body. When your email contact reads the email message, his/her email program will attempt to download the nested image. Assuming you placed the image on a web location where you can see statistics about it, you will have an email read confirmation because it will count as a "hit" (file read) on the web location where the image was uploaded.
