ListMailer

ListMailer とは？

Apple Mail doesn't let you manage distribution lists natively. You either have to go through the Contacts app, or use an external newsletter service. ListMailer fixes this. It's a native Mail extension that lives in your compose toolbar. Create mailing lists, add recipients from CSV or directly from the To/CC/BCC fields of any email, and send to your groups with one click. No app-switching, no web logins.
