If you’re sick of wondering whether your email has even been opened, then you can use Apple’s Mail application to request read receipts.
There’s plenty of reasons why your unopened email might hang around in the recipient’s inbox for a while – maybe they’re out of office perhaps they’re travelling and don’t have access to the Internet, or maybe they’ve left the company and no-one is monitoring their inbox. When you send an email, you can usually be confident that your message will be delivered quickly and without any issues – but how do you know whether the recipient has actually opened your message?
