I hope someone can shed some light on how to achieve this.

The Problem.  

I have an automated process setup on a potential which monitors the signing up and transfer of an business energy contract from a current supplier to a new supplier.

A selection of emails is sent to the contact listed on the potential to inform of progress. The contact is added via a look up field.

Now I want to additionally send a few emails to an additional email address at key points during the transfer. This is in case the main contact is away from work.  I will also use someone who is higher up in the organisation which has the benefit of a) keeping them informed and b) shows them we are giving great service. The latter then makes it easier to approach them for referrals.

I reasoned the additional emails should be on the account record as they would be relevant to any potential within that account.  We often have many potentials for a given account.

I have added the additional account details onto the account record by way of a contact lookup field.  

What I have found though is that in the auto process I can not send an email to a contact associated with the Account. 

If I add an email field to the account record it works.  But logically it should be a contact record attached to the Account otherwise I will be holding data in 2 places.

As anyone encountered something similar?

Apologies if I have not explained that too well.

I am quite new to auto processes.

As an aside it would be nice to know which potentials have processes running.  You can never be sure if what you thing should be happening is actually happening.
