Hi there I have a feeling my email account has been hacked and someone is changing the bank details on my invoices. I keep getting notifications to say I have looked at my invoice, which I haven’t.
If you’re sending yourself a copy of the invoice and or open an old invoice you can get those read receipts, or if you’ve got a email reader that opens them.
If you think you’re account is hacked reset the password. If it’s a Google account they’re usually pretty quick at catching it.
WHen I’m testing bullet I sometimes get confused with the read receipts. They’re not an exact science.
