# Bad-language filter out of sight, one click away

List the words you would rather not read, or switch on a default list. Mail carrying one opens behind a warning, and nothing is deleted.

In short

## What is an email profanity filter?

A profanity filter checks text against a list of words and acts when one turns up. The hard part is matching: a filter that wants exact spellings lets f#ck through, and one that looks inside words silences Scunthorpe.

How it works

## Spacing and symbols do not slip past

Case, spacing and stretched letters are ignored, and the usual stand-ins, like 1 for i, count as letters. With idiot on your list, 1d10t, i.d.i.o.t and IDIOOOT are held too.

## Whole words only, never inside one

A list holding ass leaves a message about a class alone, and the default list lets Scunthorpe through.

## Checked as you read, not on arrival

Add a word today and the message that made you add it is held the next time you open it.

What you get

## In the product today

Held, not deleted

It stays where it is, behind a warning, until “Show it anyway” opens it.

Never quotes the word

The warning names no word and gives no count.

Your words and ours

Your own list, plus a default one, under Privacy in your workspace settings.

Per domain or address

A domain, or one address, can keep a word list of its own.

Good practice

## Getting the most out of it

1. 01
   
   List every form
   
   Only whole words match, so idiot does not hold idiots. Add each form you mean.
2. 02
   
   Paste the lot
   
   Commas, spaces and new lines all separate entries, so a whole list pastes at once.
3. 03
   
   Start from the default
   
   Switch the default list on first, then add only the words it misses.

Where it stands

## Good to know

Questions

## Asked often

Keep going

## Works well with

Block a sender or a domain

One address, or everything from a domain, stopped before it reaches you.

Rules you write yourself

Your own conditions, and what should happen to anything that matches them.

Remote image control

Stop a sender fetching anything from their own server while you read.
