Some SendGrid Connectors Failing Due to Missing marketing_campaign.read Scope

This incident has been resolved. We have observed that instance rates are returning to normal levels and affected connectors are syncing successfully.

Incident Summary

Description:
Some SendGrid connectors began failing with a missing "marketing_campaigns.read" permission error. This was due to recent changes in how SendGrid handles API key scopes, which impacted access to marketing-related tables.

Timeline:
Issue began on Jul 26, 2025 at 15:00 UTC
Resolved on Jul 28, 2025 at 15:30 UTC

Cause:
SendGrid began enforcing scope restrictions on API keys, removing marketing_campaigns.read for accounts without Marketing Campaigns enabled. This caused sync failures for connectors trying to access marketing-related tables.

Resolution:
We deployed a backend fix to automatically exclude unsupported Marketing tables when the required scopes are missing, allowing affected connectors to sync successfully.

We have implemented the fix and are now closely monitoring the results to ensure the issue is fully resolved.

We are preparing a fix to exclude all marketing tables in case of scope absence.

Summary:
Some SendGrid connectors are currently failing due to missing `marketing_campaigns.read` permissions. This permission is now being enforced by the SendGrid API for non-Event tables. Accounts without Marketing Campaigns enabled cannot grant this scope, leading to sync failures.

Workaround:
If your SendGrid account does not use Marketing Campaigns, please go to your connector’s Schema tab and de-select all tables except Event. This will allow the connector to sync successfully.

Next Steps:
Our engineering team is actively working on a permanent fix that will automatically exclude unsupported tables for accounts lacking the required permissions.
