Mass e-mail from a module that does not have native e-mail support

[Guido1982]

We would like to send an e-mail about a software update to customers that have a particular type of asset (the asset needs to be linked to a particular product). Now I know that we can send bulk e-mails from listviews like accounts and contacts, that have native e-mail support. Could we do the same thing for a module like assets easily? Like copying some business actions over to assets and by that, active bulk e-mail behaviour to the listview of assets?
