Can a reply to an ongoing email conversation land in spam?
Had an exchange of emails with someone, around 4-5 back and forth emails.
He then told me that my last reply never arrived. When I forwarded that email again to him, he told me that actually the original reply arrived but landed in spam... he checked it after I forwarded the initial reply.
It's not critical or even a super important conversation but I think he lied to me. Is there any chance that a reply lands in spam if the last 4 mails in a thread arrived without a problem?
The emails were sent from a custom domain, using Office 365 Business. I have that email address for more than 6 years and I never had a problem with my emails landing in spam or never arriving. It's the first time I am hearing about it but I think he is duping me.
Edit Thanks all for the replies, it's good to know that it can happen.
Absolutely NEVER mark anything from an online email provider you want to keep as spam. They use shared systems, it's not just spam for you, but potentially for everyone on that email provider. That's one way to protect people from receiving spam, 100 users marked that same newsletter email as spam? Alright, the newsletter will go to the spam folder for the next 20k users.
If you mark legitimate emails as spam for fun you're fucking up the system (and give the sender a massive headache if suddenly every @gmail.com receiver puts their emails into the spam folder).
Worst case: Your 'temporary' email account gets banned for spamming (new account, first email sent is marked as spam by receiver). Then your original email account is banned too for ban evasion (same IP, same browser fingerprint, they know it's you).
Just don't mess with the spam filters on a server that doesn't belong to you.
