Question:

Am I allowed to send out emails to haram food stores, offering to promote their products? Or is it impermissible, the same way we are not allowed to advertise for alchohol?

Answer:

If it’s lamb, beef e.t.c that their only problem is that they are not Islamically slaughtered, then it is permissible given that it is advertised for non-Muslims to whom these products are considered permissible to eat.
