Break Exchange 2013 Message to small batches

I live in the central US where Comcast is King and they have some really stringent rules when it comes to emails sent to "anyone"
I have a client that sends out a newsletter to 400-700 recipients.
Anywhere from 50 to 75 percent of any given mailing will be to email addresses
with exchange 2013 server set at defaults I am getting the dreaded error
452 4.1.1 Too many recipients for message on the outbound queues that are going to

We have tried Constant Contact, and they didn't like it. It required too much scripting.

They really don't want to manually break the list down into pieces to sent it out in chunks because they feel that it is too much to maintain.

Is there a way from within Exchange 2013 where if an outbound message has more than x number of recipients, it will break that into smaller chunks automatically and stagger/delay the sending of each batch ?
I think if we can do that we can stay under Comcast's  25 concurrent connection, no more than 100 recipients per message, no more than 1000 recipients per day rules.
Any help would be much appreciated

Thank you for the input looks very much like constant contacts
The person designing the bulletin has a template in word that she uses to create it, which has specific formatting, columns,  and embedded images already in it.. she knows how to use that. She is adamant about using this for creation. So I really need a way to make this work through exchange.

Have you looked into email merge with Word.  Each message is individually addressed and sent from the recipients list.  The main doc is already in Word format.

The recipient list can be excel, access, or something else (Outlook contacts).

Bad addresses are returned individually.

I have not .. we can try that .. it would solve the number of recipients per email  problem but we will still need to throttle the number or simultaneous emails to the domain .. or any other domain for that matter ...

Comcast is being totally unrealistic they have millions of customers with email addresses so they are limiting you to 30,000 users getting 1 email per month! I knew that Comcast was a terrible isp but not at this scale.

well we haven't completely lost the customer .. but we will no longer be handling their email .. they are moving to office 365 for email with their district office in control .. I have a feeling that their district office is going to force them to use Microsoft mail chimp for their bigger emails. .. I wish them Luck .. Thanks for all you guys tried to do ..
