GroupMe vs Missive

GroupMe has a built in function to read receipts.

GroupMe has an excellent web client that can be used to send and receive messages and manage groups from the desktop.

Allows sending messages from web services via IFTTT.

It's possible to add location and time with reminders directly in the GroupMe app.

GroupMe has settings that allow muting a single group or turn off all GroupMe notifications from within the app.

GroupMe can set up a custom phone number which allows people without the App to send and receive messages. This makes it easy to add anyone to messaging.

In Missive you can live edit an email draft with your teammates, the draft composer acts exactly like a Google doc. Each team member has a different color cursor.

The email section allows for consuming all of your email accounts in it, utilizing shared addresses (help@acme.com), personal work inbox (philippe@acme.com) and personal inbox (phil@gmail.com).

It’s important because the collaborative part of Missive becomes useful when users consume all of their emails within the app. You not only want to collaborate around emails sent to your company help@address, but also around the really important emails you most likely receive at your personal company address, like that really important email you received from a potential high profile partner.

Missive is also a team chat app. When using Missive you can ditch your email client, chat app and help desk.

Merge all email accounts in one unified inbox.

You can create multiple tasks per conversation all assignable to a single or a group of persons.

Nicely written software. Always works as you'd expect, beautifully designed, a classy piece of software.

Supports multiple organizations with one user login.

Know exactly if and when the recipients read your important email.
