I created an email (either outlook or gmail) and sent some people emails. Later, when I tried to log into my email, I was given a notification that my account has been marked as a spam account. Does this mean that my emails were sent to the spam folder. How can I guarantee that an outlook or gmail account is delivered to its intended recipient without being in the spam folder? And is there a way of knowing afterwards whether an email was delivered to the inbox and not the spam folder?
Also, I'm sending legitimate emails. I'm not mass emailing anyone, I probably emailed five people and the content of the email included one link and several attachments. Is this why, and if it is, how can I overcome this?
@baldPrussian - Its not even how does SMTP work. Most spam filters are beyond SMTP. – Hector – 2018-01-16T20:58:58.030
This doesn't really sound like an IT security question as much as a "how does SMTP work and how to best manage it" question. – None – 2018-01-16T20:58:02.177
The sender cannot know about the folder a message ends up in at the recipient's end. Doesn't deal with SMTP and not necessarily even with spam filters, since the recipient may have personal filters/rules. – None – 2020-01-01T08:41:20.680
This would be impossible to guarantee for many reasons ranging from email server hacking and email account access compromised to the mundane auto spam filtering or the intended person has someone that screens and possibly answering most emails received. – Steve Kinzey – 2020-01-02T22:40:55.163
