Postcards for Slack (Invite Only Beta)


Postcards for Slack is a fully managed integration between Skyetel's SMS/MMS and Slack. By using this product, you are able to send and receive SMS and MMS from your Skyetel phone numbers via Slack. 

Installing Postcards for Slack

Installing Postcards for Slack is invite only right now. 

Once you have connected Postcards to Slack via the Skyetel Portal, you need to create the channel for the Skyetel DID. The best way to do this is to simply send yourself a new SMS, and Postcards will create the new channel for you automatically. Once the channel is connected, you simply have to add yourself to it to get started.

Receiving Messages

Once you get everything setup, you'll see your Skyetel DID as a channel:

Inbound SMS messages will automatically create a new SMS Thread with the source phone number, and any replies inside that thread will send a reply to the party that originated the message:


Any member in the Slack Workspace that has access to the Channel is able to send a reply, and view conversation threads:

Sending New Messages

You can initiate new SMS messages by typing /sms into the Slack Channel:


Postcards will privately confirm to you when the SMS has been successfully sent:


and you will see the new conversation in the Channel:


Thread Timeouts

Postcards will automatically timeout a thread after 24 hours of inactivity. This means that you may have duplicate threads for incoming messages. This prevents missing a message from a party who sent you an SMS a long time ago, and then tried again to get back in touch more recently.
