SendGrid is down: Microsoft Feedback Loop (Spam Reports) Processing Delays. Immediate workarounds for indie hackers.

BREAKING: SendGrid Experiencing Microsoft Feedback Loop Processing Delays

Status: IDENTIFIED | Severity: MINOR | Impact: Partial Disruption

Last Updated: [TIMESTAMP]

---

What's Down & Who's Affected

SendGrid's Microsoft Feedback Loop integration is experiencing processing delays. This specifically impacts:

Spam complaint handling from Microsoft Outlook/Hotmail users

Bounce rate calculations that rely on real-time FBL data

Automated unsubscribe logic triggered by complaint signals

Reputation monitoring dashboards showing FBL metrics

Who this affects: If your app sends to Microsoft domains (@outlook.com, @hotmail.com, @live.com) and relies on automated complaint processing, you're impacted. Most indie hackers won't notice immediate issues—transactional emails still send fine.

What still works: Email sending, delivery to inboxes, basic bounce handling, and other ISP feedback loops (Gmail, Yahoo, AOL).

Immediate Workarounds (Do This Now)

1. Disable Auto-Unsubscribe on FBL for Microsoft

Temporarily skip automated unsubscribe logic for Microsoft complaints:

```python

Pseudocode - adjust for your stack

if complaint.source == 'microsoft_fbl': # Log but don't auto-unsubscribe yet log_complaint(complaint) notify_admin(complaint) else: auto_unsubscribe(complaint) ```

2. Use SendGrid Webhooks Selectively

If you're listening to SendGrid complaint webhooks, manually validate before processing:

```javascript // Check timestamp against delay window if (Date.now() - complaint.timestamp > 3600000) { // Complaint is >1hr old, may be delayed - investigate manually queue_for_manual_review(complaint); } ```

3. Increase Monitoring Frequency

Check your SendGrid bounce/complaint dashboard every 15 minutes instead of hourly until resolved.

4. Manual Review Protocol

Ask support (support@sendgrid.com) to manually check complaint status for high-value campaigns sent to Microsoft domains in the last 24 hours.

How to Check If Your Project Is Affected

1. Check SendGrid Status Page: https://status.sendgrid.com (look for FBL/complaint processing notices) 2. Review Your Metrics: Dashboard → Suppressions → Complaints. Are Microsoft-sourced complaints missing or delayed? 3. Query Webhook Logs: If you ingest FBL webhooks, check timestamps—are they catching up or stalled? 4. Test Send: Send a test email to a Microsoft account and monitor for 2 hours. Normal flow = unaffected.

Alternative Tools to Consider (Temporary)

If Microsoft FBL is critical to your workflow:

Postmark – Excellent FBL handling across all ISPs; easy API migration

Mailgun – Robust complaint processing; better Microsoft integration parity

AWS SES – Simpler FBL (fewer features, but stable)

Twilio SendGrid alternatives – Consider for next major refactor

Don't migrate yet. This is a MINOR delay, not a full outage. Wait 4-6 hours before switching.

---

Monitor for Recovery

Follow: https://status.sendgrid.com (refresh every 10 min)

Watch for: "Microsoft Feedback Loop Processing" status → "Operational"

Expected timeline: SendGrid typically resolves FBL delays within 2-4 hours

Verify: Once marked resolved, run a test send and confirm webhooks trigger normally

---

Bottom Line

Your emails are still being delivered. Spam complaints from Microsoft users may be delayed in reaching your account—check manually if it matters for your product. Stay calm and monitor.
