In the context of email troubleshooting, what could indicate a problem with delivery?

The indication that specific users are not receiving the email points to a delivery problem because it highlights a targeted issue within the email communication process. This scenario suggests that while the email system itself may be functioning correctly, there could be factors affecting delivery to those particular destinations.

For instance, there could be issues related to the recipients' server settings, their inbox being full, spam filters blocking the email, or even the possibility that their email address is incorrect. This specificity helps narrow down troubleshooting efforts to understand why certain individuals are impacted while others are not, an essential step in resolving email delivery issues.

Other potential indicators listed may affect overall functionality but do not specifically point to delivery challenges. The unsent status may suggest an issue but does not confirm delivery problems for particular users. Similarly, misconfigured user settings may hinder the sending capability but are not directly indicative of why a few users might not receive emails. Changes to the email template could affect the presentation of the email, but unless directly tied to delivery failures, it wouldn't specify why certain users aren't receiving them.
