People frequently think of email security as a problem with finding threats, but for many healthcare organizations, it is also a problem with how work gets done. Staff do not just deal with dangerous emails. They have to deal with junk mail, lost messages, false positives, and the daily annoyance of attempting to work through overloaded inboxes.
Quarantine can also make support work more difficult when there are too many low-value or borderline signals that need to be looked at by hand, but direct-to-spam filtering can simplify filtering.
Spam Folder Routing is a feature of Paubox that helps keep the inbox cleaner while giving you better control over phishing, malware, ExecProtect, and data loss prevention (DLP) events. The end result is a simpler workflow, fewer routine problems, and more time for IT staff to deal with the most serious concerns.
Why do email support tickets pile up in the first place
Email support tickets pile up because the inbox is already overloaded before the help desk ever gets involved. According to a JAMIA study on electronic inboxes in healthcare settings, clinicians can get about 77 messages in their inboxes per day. It can take them about an hour to deal with that many messages, and sometimes even longer. They have less time to thoroughly filter through communications and reply consistently. A meaningful share of that work also happens outside normal hours, which signals that inbox management is competing with patient care rather than fitting neatly around it.
Messages from patients, test results, staff communication, and system-generated alerts all come through the same channels. Consequently, emails have to compete with routine notices, low-value updates, and administrative clutter. The study, The Burden of Inbox Notifications in Commercial Electronic Health Records, notes, “We found providers receive large quantities of EHR-based notifications, making it harder to discern important vs. irrelevant information and increasing their risk of overlooking abnormal test results.” In a single day, the number of message views may exceed hundreds, and switching between inboxes and other displays often makes things even more difficult.
What direct-to-spam filtering actually means
Direct-to-spam filtering means an email system automatically routes messages it judges to be suspicious, unwanted, or low trust into the user’s spam or junk folder instead of placing them in the main inbox. In real life, it is a triage decision. The mail does not appear completely safe; it is not delivered to the main inbox. Instead, it might not be completely removed or put in a separate review queue for administrators.
The middle step matters because spam remains a huge share of email traffic. One Heliyon review notes that spam accounts for 56.87% of worldwide email traffic, while Gmail reportedly receives 50% to 70% unsolicited mail, which helps explain why providers need a more nuanced sorting layer between inbox delivery and outright blocking. Filters therefore decide before the user sees the message, using signals such as sender legitimacy, authentication alignment, known malicious link patterns, and content that resembles earlier spam or phishing attempts.
Some filters also use heuristics and machine learning to sort messages by patterns instead of just one rule. In that way, direct-to-spam filtering is not only about stopping rubbish. It is about transferring mail that is unsure or undesirable out of the main process so that users are less likely to deal with it right away.

Why quarantine creates unnecessary support work
Quarantine makes it more difficult for users and administrators as it turns typical uncertainty in email filtering into manual recovery duties. The Heliyon study notes that spam makes up more than half of all email traffic throughout the world, and some major providers say that 50% to 70% of incoming mail is not intended. Email systems have to make risk decisions on a huge amount of unwanted data. In light of this pressure, filters sometimes separate real communications from those that look suspicious.
About 20% of emails that require authorization don't make it to the inbox. The result is that consumers often cannot observe security working effectively; instead, they see a message that is missing and interrupts their day. A user creates a ticket because they never got an email from a supplier, a staff member asks if a message is held in quarantine, or an administrator has to check and redirect mail that was screened too strongly. Higher spam thresholds can make your mailbox less likely to get spam, but they also make it more likely that real messages will be lost unless an administrator steps in.
How Paubox supports direct-to-spam filtering
Paubox, as a HIPAA compliant email solution, supports direct-to-spam filtering through its Spam Folder Routing feature, which can be configured so that spam and gray mail are delivered to the end user’s spam folder instead of quarantine. That keeps those messages out of the main inbox while still allowing users to check their spam folder themselves for expected mail, which can reduce the need for routine quarantine-related support requests. Paubox is clear that Spam Folder Routing applies to spam and gray mail, while higher-risk categories such as phishing, virus, ExecProtect, and DLP do not get routed to the spam folder.
Paubox also offers other features that can make email workflows more manageable, but they should be described separately from Spam Folder Routing. Paubox announced in February 2026 that an observe-and-report mode for DLP was an upcoming feature that would send weekly reports without quarantining messages, so it is more accurate to describe that as a planned capability discussed by Paubox rather than a generally available feature unless product documentation confirms release. Current Paubox DLP documentation describes DLP as quarantining emails that match configured rules, with administrators then able to review and release or block them.
FAQs
How is gray mail different from phishing or malware?
Gray mail usually includes bulk messages like newsletters, promotions, notifications, and other low-priority emails that are not necessarily malicious.
What is the difference between spam-folder routing and allowlisting?
Spam-folder routing controls where suspicious or low-value mail goes. Allowlisting tells the system to trust a sender or domain more broadly, which should be used carefully because it can reduce protection if abused.
Can users become too reliant on checking their spam folder?
That can happen if filters are too aggressive or poorly tuned.
