An error says my rule will never match; what can I do?

If you are getting an error message like this one when saving your rule…

An example of an impossible combinaison of rule conditions.

…it means the conditions will never match any message.

In the image above, it will always fail because an email cannot come from more than one From email address, and because the rule expects All conditions to match.

To fix this, you could change the first select box of the rule from:

All of these 3 conditions must match:

to:

At least one of these 3 conditions must match:

But in the above case that's probably not what you would expect. You probably want a message to match if it contains a subject with the word "invoice" and it is sent from either "alex@acme.com" or "bob@acme.com".

To do so, you would need to nest one of the From conditions in a new block by pressing the > arrow:

Nest a condition block.

In the new condition block, switch from All to At least one condition matched. The end result should look like this:

A nice rule!
