    We know the most common ones, but would like to know from the actual users what they faced.

    most likely, sending emails to outdated and invalid email addresses.

    Sometimes my sending IPs are blocked by public backlists, like Spamhaus ZEN and UCEPROTECTL2/L3. My hosting instances sometimes got vulnerable PHP scripts from clients then I always need to scan and secure them. Spamhaus allows unblocked by yourself but UCEPROTECTL2/L3 doesn't.

    machine open emails.

    Machine-opened emails are used by people who do not want to read an email but must subscribe to receive the benefits. So a robot opens the email, and while some Webmail platforms may not make distinctions, most do. This means that your mail is considered a bounce or fake delivery. The numbers are astronomical at times and it can be costly to eliminate them.
