Hello everyone. I hope that you have a great day so far. I was wondering on tracking emails. I was using read Receipts with Mozilla Thunderbird, but it stopped working. I don't use Gmail, as you may notice. I looked everywhere. I was wondering if there is a software where I can paste an image to the signature. Thank you.
