How Arist Messaging Works:

Arist uses Twilio to push messages out via SMS and WhatsApp. These two channels make use of global SMS infrastructure to send and receive messages. This introduces a number of variables in the time we deliver a message and time it actually displays on a Learner's mobile device.

Fun Fact: Our longest time to transmit a message to Twilio is only 17 seconds. 99% of our messages reach Twilio within 1.2 seconds.

Delivered vs Received:

When a Learner hasn’t received a message it does not necessarily mean that we didn’t deliver it. With SMS especially, there are many outside factors that can lead to a message not making it to the user including:

  • content filters

  • bad reception

  • phone powered off

  • phone provider (sprint, verizon, at&t) blocked the message

Message Types:

Arist sends the following messages throughout the course experience:

  • System Messages - Confirming Enrollment, Answer receipt, etc.

  • Course Lessons - Main course content including images, body text, and questions

  • Responses - after a learner answers a question responses are sent

All of these message types are processed and sent immediately by the Arist Messaging System, but they are still subject to certain deliverability variables based on the realities of global SMS infrastructure and misalignment of Distribution Settings.

I Didn’t Receive My Lesson, Why?

Sometimes messages are not delivered when expected because Delivery times were not clearly explained in the Course Description.

e.g. If you have a course that only sends at 12pm daily and a Learner enrolled in the course at 3pm, they will not receive their day 1 lesson until the next day at 12pm.

Aside from that, most delivery problems are caused by Mobile Carrier issues.

Common scenarios include:

  • Phone is turned off or out of service - In this case, messages should deliver when the phone is turned back on or regains service.

  • Wrong Phone Number or Country Code

  • Content Block - Mobile Carriers (like Verizon, Sprint, etc.) will sometimes block messages for content reasons. If your lessons contain language triggers their spam filter, the carrier may block the message. The filters that Carriers employ are always changing so it can be hard to predict what content will get blocked but we recommend avoiding the following:

    • Overuse of ALL CAPS phrases. Instead use an emoji to add emphasis

    • too many links in one message

    • Bad language, or suggestive dialogue. Keep it clean folks!

    • Copyright protected material.

    • Gaming or Gambling language. e.g. JACKPOT!!! NOW’s YOUR CHANCE TO WIN!

Getting More Help:

If you’ve ensured that your learners have service at the time they expect to receive messages and content is not likely to trigger a spam filter, feel free to contact and send us:

  • the phone number of the Learner

  • a link the course they expected to receive

  • and your learners Enrollment ID

And our team can investigate any message deliverability issues.
