Setting up custom rules in Fyxer

Custom rules and inbox control.

Fyxer gives you more control over how emails are categorized by letting you create your own custom rules, without disrupting the rules and folders you already use in Gmail or Outlook.


How Fyxer works with your existing Gmail/Outlook rules

Fyxer is designed to coexist with your current setup, not overwrite it.

Respect my labels/rules:

You'll see a setting in Dashboard → Categorization → General to respect your existing categories.

This setting ensures Fyxer never unexpectedly overrides rules you already rely on.

  • Respect my categories = ON (recommended): Fyxer skips emails that already have a Gmail/Outlook label or rule applied. Great if you already have systems you trust

  • Respect my categories = OFF: Fyxer categorizes every email, even if another rule has already acted on it. Gmail filters and Outlook rules always process emails first, and Fyxer steps in after. This ensures that user-applied labels from Gmail or Outlook filters are respected before Fyxer acts. Choose this if you'd prefer Fyxer to handle everything


Create custom rules inside Fyxer

Custom rules let you fine-tune how specific senders should be categorized.

How to create a custom rule:

  • Go to DashboardCategorization → Advanced → Custom rules

  • Click Add email or domain

  • Choose your rule type:

    • Sender email (e.g. [email protected])

    • Domain (e.g. company.com or @company.com)

    • Exact subject line (e.g. "Invoice overdue")

  • Choose the Fyxer category you prefer (To do, FYI, Marketing, etc.)

  • Save

Fyxer will automatically apply this rule to new incoming emails.

How custom rules work in the background:

If more than one rule could match an email, Fyxer prioritizes in this order: specific email first, then domain, then subject line.


Smart ways to use custom rules

Custom rules are powerful. Here are some of the best ways to use them.

Reduce inbox noise

Move recurring low-value emails out of your inbox, such as:

  • Newsletters

  • Notifications

  • System-generated emails


Prioritize key senders

Guarantee that important senders always land in To do. For example, your manager, investors, VIP clients, or internal teams whose emails you never want to miss.

Exclude emails from Fyxer labeling completely

If you don't want Fyxer categorizing certain emails (e.g., invoices, personal folders, automated accounting feeds), create a rule directing them to "No label". This prevents these emails from being categorized and moved out of your inbox, but keeps Fyxer categorization on other emails.

You can also use the "No label" rule to prevent Fyxer from generating automatic draft replies for specific emails.

Avoid overlapping rules

To prevent conflicting behavior:

  • Use Gmail/Outlook rules for filing, archiving, or forwarding

  • Use Fyxer rules for categorization and prioritization

This keeps things clean and predictable.
