**Global email filters** apply to *every* mailbox on your domain at once, not just one account. They are perfect for domain-wide rules – blocking a persistent spammer or routing certain mail for everyone. This guide shows how to use them.

## Global vs. account filters

A normal [email filter](https://jethost.com/kb/how-to-create-email-filters/) affects only one mailbox. A **global** filter affects all of them on the domain. So use a global filter for something that should apply to everyone, and a per-account filter for personal sorting.

## Create a global filter

1. In your hosting panel, open **Global Email Filters**.
2. Click **Create a New Filter** and name it.
3. Set the **condition** – for example, *From* contains an address, or *Subject* contains a word.
4. Choose the **action** – discard, redirect, deliver to a folder, and so on.
5. Click **Save**.

## Filter order matters

Filters run from top to bottom, and the first matching rule usually decides what happens. So put your most specific rules near the top and broad catch-all rules lower down. If a message seems to vanish or ignore a rule, an earlier filter has probably already acted on it. Test a new rule with a harmless action first, such as adding a header or delivering to a folder, and switch it to discard only once you are sure it matches exactly what you intend.

## Good uses for global filters

- Block a domain that spams every address you have.
- Discard messages containing a phrase you never want delivered.
- Apply a company-wide policy without editing each mailbox by hand.

## JetHost Experts Tip

Be extra careful with “discard” on a global filter – it applies to every mailbox, so one broad rule can silently drop real mail for the whole company. Test with “deliver to a folder” first.
