I sent couple of emails via Mailspring app to my friend and we found out that Mailspring app notifies me that my friend is OPENING these emails at times like 3AM, 4AM…which she is not. Yesterday we set up an email, where I put a geolink trap…this email was again opened by someone which was not her…but that subject (could be a bot??) did not click on the geolink url which would localise him/her.
Any ideas why this is happening? Is someone spying on her emails?
