Spam messages can pile up quickly, clutter your team's inboxes, and even lead to potential security risks. With Zoho TeamInbox’s anti-spam filters, you can easily detect and block suspicious emails, keeping your shared inbox clean and distraction-free.
It has Allowlists and Blocklists settings that lets you control who can reach your workspace while making it easy for your team to collaborate without distractions or potential threats. Whether your team is remote, handling customer support, or managing internal communication, these filters help everyone stay focused, safe, and efficient.
Why spam protection matters for your inboxes
Spam isn’t just annoying—it’s a potential threat to your business security. Unwanted emails waste your team's valuable time, and can even hide phishing attempts that may put your business at risk.
- Wasted time and reduced efficiency: Teams often waste their time sorting through spam messages that could have been filtered automatically.
- Security concerns: Some spam emails carry phishing links or attachments that can compromise company data.
- Inbox clutter: Important customer messages or internal updates can easily get buried under piles of unwanted mail.
By using spam protection in Zoho TeamInbox, you make sure every incoming email is scanned and filtered, so your team only sees what’s relevant and safe. It not only improves productivity but also helps your organization maintain a clean and efficient workspace.
How does Zoho TeamInbox’s anti-spam filter work?
You have two simple tools to take control of spam emails for your shared inbox.
- Allowlist: Add trusted email addresses or domains here so their messages will be one step closer to getting delivered in your inbox. For example, if your team often communicates with customers from certain companies, you can add their domains here to make sure their messages don't accidentally get marked as spam.
- Blocklist: Add suspicious or spam-heavy addresses or domains to this list, and their emails will automatically move to the spam folder before they reach your team.
Once set up, these tools automatically filter incoming mail. You can review, edit, or update your filters anytime to keep your settings updated as spam patterns evolve.

Here’s how different teams can use anti-spam features:
- The customer support team can add email addresses or domains of high-value customers to an Allowlist for faster service.
