Group messaging is definitely a known problem. Different people have their own group messaging problems. The #1 problem in group messaging is always on finding that lowest common denominator platform within the group. Dealing with mostly iPhone users may lead you to use iMessage exclusively. But, if you have to deal with Android users, you may have to rely on cross-platform solutions such as WhatsApp or SMS.
There are also other impromptu needs that are not suitable for SMS, e.g. sharing the group photos you just took with newly-met business associates or sending notes to all the meeting attendees. For these cases, you may have to rely on emails instead.
Regardless what your needs are, the built-in iMessage and Mail apps in iOS are not built for sending these messages quickly on your iPhone/iPad. For example, you can’t easily group (and ungroup) people in your Contacts list whom you frequently send messages/emails to. Sending multiple photos from within these apps is not easy, either.
Fortunately, Contrast — the development team behind Launch Center Pro — just released two new apps aimed to ease these problems: Group Text+ to send group iMessage/SMS, and Email+ to send group emails.
Shortcuts to Groups and Individual Contacts
Both GroupText+ and Email+ offer a new approach in the way you manage your frequently-used contacts. I’d suggest you browse your existing behavior in both iMessage app and your Sent Mail folder to determine the best way to use this feature.
Both apps allow you to create pre-defined groups (such as Co-workers, Family, etc.), add individual contacts, and rearrange them in any order. Each time you want to send a new message/email, you can mix and match these icons to fit the needs. For example, you may want to share your holiday vacation photos with your co-workers, family, and one specific friend you meet during that period.
