Troubleshooting SMS and Email Notification Issues in Stack

Are you or your users experiencing issues with receiving SMS or email notifications in Stack? Let's explore some common reasons why this might happen and how to resolve them.

Understanding Workflows in Stack​

Workflows in Stack are a powerful tool that combines the functionalities of Triggers and Campaigns into a single, streamlined process. This means you can manage all your automation needs efficiently within one builder.

Common Reasons for Notification Issues​

  1. Incorrect Contact Information: Ensure that the contact details, such as phone numbers and email addresses, are entered correctly in your Stack account. Even a small typo can prevent notifications from being delivered.

  2. Opt-Out Status: Verify if the recipient has opted out of receiving messages. If they have, Stack will not send notifications to them.

  3. Notification Settings: Double-check the notification settings within your account. Make sure that SMS and email notifications are enabled for the desired actions.

  4. Spam Filters: Sometimes, emails might be caught in spam filters. Ask recipients to check their spam or junk folders and mark your emails as 'Not Spam' to ensure future delivery.

  5. Carrier Issues: Occasionally, SMS messages may be delayed or blocked by carriers. If this is suspected, contacting the carrier for more information might help.

  6. Workflow Configuration: Ensure that your workflows are set up correctly. An error in the configuration can prevent notifications from being sent. Review each step to ensure everything is connected properly.
