Rules email action "from" field

Hi I'm new to using Rules in D7. I'm on Rules 7.x 2.3.

I've setup a relatively simple rule to send an email to users of a specific role when a new piece of content of type X is saved.

I'm in development and testing with the site, so started off with sending the emails from the default (my primary email), but went back in and edited the rule to come from an email that belongs to the client.

In actions, I have a valid email address in the "Value" field under "From", but it still sends the email from the default address. I've cleared the cache and tried posting to trigger the rule with a clear cache and the recipient still sees the email as from the default email.

Am I missing something?

Thanks!
