Is it permissible for an IT company to assist a company that produces alcoholic beverages in marketing its products by providing contact information, with the intention of donating the profits to charities, and is it permissible to give this money in charity?

There is no impediment to providing a company with information to promote its permissible products, such as water and soft drinks. However, it is forbidden to provide it with information to promote prohibited items, such as alcohol, or things where the permissible and impermissible are mixed and cannot be separated, such as hotels. This is because it falls under cooperating in sin and aggression. The intention to donate money earned from promoting forbidden things does not make this action permissible, as earning forbidden money with the intention of donating it is not allowed.
