Many senders want to get a confirmation from the recipient that their email was received and read. In G-Lock EasyMail7 there is no special option you could check to request the read receipt from the recipient. But you can use custom header fields to insert the read receipt in your messages sent from G-Lock EasyMail7. You can use custom header fields at the email server account level or at the workplace level.
Click on the Workplace menu in G-Lock EasyMail7.
Click on "Email Server Accounts", select the account and click Edit. Then go to the "Custom Headers" tab. Here you can define custom header fields that will be added to all messages sent from this account.
Or, click on the “Workplace Settings” and go to the "Custom Header Fields" tab if you want to insert the read receipt in all messages sent from any account within the current workplace.
