So what happens if you want to send a message to, say, everyone in the marketing department, or a select batch of customers? If you're using an iPhone or iPad, you have little choice but to manually select their email addresses, one after another.

Until Apple corrects this glaring oversight (and perhaps even after), look no further than .

This ingenious app lets you build email distribution groups, then adds those groups to your address book, where they’re accessible from all other apps. It’s even Siri-friendly.

The app is a breeze to use. First, you create a group (Sales Team, for example), then choose the contacts you want to add to that group.

You can pull names from your contact list (either one at a time or using a checklist) or enter addresses manually via the Import option.
