Error 30037 occurs when outbound messaging has been disabled for the account. Messages cannot be sent until the sending restriction is removed.

TABLE OF CONTENTS

What Is Error 30037?

Error 30037 means the account is currently configured so that outbound messages cannot be sent.

This is an account-level restriction, which means the issue is not necessarily related to the recipient’s phone number, message content, or carrier.

Key Benefits of Identifying an Account-Level Restriction

Recognizing that the issue is account-wide helps you avoid unnecessary troubleshooting.

  • Faster Diagnosis: Focus on the account’s messaging status instead of individual contacts.


  • Fewer Repeated Failures: Prevent workflows and campaigns from continuing to attempt blocked sends.

  • Better Account Control: Confirm whether outbound messaging was intentionally disabled.

  • Clearer Support Escalation: Gather the correct information before requesting help.

Common Cause of Error 30037

The primary cause of Error 30037 is:

  • Outbound messaging has been disabled for the account.

This may be intentional or may require review if you believe the restriction was applied incorrectly.

How to Fix Error 30037

Start by reviewing whether outbound messaging is expected to be available for the account.

  1. Confirm that the error affects outbound messages.

  2. Check whether multiple contacts or messages are failing with the same error.

  3. Pause active workflows or campaigns that are continuing to send.

  4. Review any available account notifications related to messaging restrictions.

  5. Confirm whether outbound messaging was intentionally disabled.

  6. If the restriction appears incorrect, contact support for review.

  7. Resume messaging only after outbound sending has been restored.

Check Whether the Issue Is Account-Wide

Because Error 30037 is account-level, it may affect more than one recipient.

Test whether:

  • Multiple outbound SMS messages fail with the same error.

  • Different destination numbers produce the same result.

  • Workflows and campaigns are also affected.

  • Manual one-to-one messages fail as well.

If all outbound messages fail with Error 30037, focus on the account restriction rather than individual contact records.

Pause Automated Sending

If outbound messaging is disabled, automated systems may continue generating failed sends.

Review and pause:

  • SMS workflows

  • Bulk campaigns

  • Scheduled messages

  • Automated follow-ups

This helps prevent unnecessary repeated failures while the account status is being reviewed.
