What do your logs say?
It is generally not a very good idea to have a single message with
thousands of recipients since exim basically reverts to single
threading in this case (having only one queue runner doing the
delivery). Better send the message multiple times with a smaller
number of recipients.
Other MTAs might be more efficient in this case.

Why? This is only going to trip spam filters and to - much worse -
expose your customer data.
Are you aware that mail delivery is generally not controlled by the
headers, but by the envelope?

No. Exim cannot do this without serious massaging.

There are other programs to send mail to a number of recipients pulled
in from the database. But you are of course free to reinvent the
wheel.
