The "Groups" function in MailDroid allows you to create groups for a number of email addresses. This group can then be used by any email account when composing an email. Here is the simple workflow:

Once this is done, you can simply compose an email and type the group name instead of typing multiple e-mail addresses. Once sent, recipients will be able to see all email addresses and not the group name.

In the future, more options may be added to this feature.
