SendGrid Status: How to Check If SendGrid Is Down Right Now (2026)
Updated June 2026 · 7 min read · By API Status Check
Quick Answer: Check SendGrid Status Now
SendGrid (now part of Twilio) sends over 100 billion emails per month for businesses worldwide — from transactional password resets and order confirmations to large-scale marketing campaigns. When SendGrid goes down or experiences delivery delays, the impact ranges from frustrated users missing OTPs to entire marketing lists going undelivered. Knowing how to quickly diagnose a SendGrid issue — and whether it's really an outage or a deliverability problem — is essential for any developer or email marketer.
Understanding SendGrid's Status Page (status.sendgrid.com)
SendGrid operates status.sendgrid.com — its official status page. Each component maps to a different delivery method or SendGrid product, so you can pinpoint whether your integration method (API vs. SMTP) is affected.
Email API (Web API v3)
The primary REST API at api.sendgrid.com used by most modern integrations. Issues here affect all API-driven email sends, including single sends, dynamic templates, and batch sending.
SMTP Relay
Sending email via smtp.sendgrid.net on port 587, 465, or 25. Many legacy integrations and email clients use SMTP. SMTP and API issues are tracked separately as they use different infrastructure.
Inbound Parse
SendGrid's feature for receiving and parsing incoming emails to a webhook. Issues affect inbound email workflows — typically isolated from outbound email delivery.
Marketing Campaigns
The email marketing platform for contact list management, campaign creation, and bulk sends. Issues here affect the SendGrid UI and scheduled campaign delivery.
Email Activity Feed
Real-time logs of email events (opens, clicks, bounces, deliveries). Activity Feed delays mean you can't see whether emails were delivered, even if they actually were.
SendGrid Dashboard / UI
The web interface at app.sendgrid.com. Dashboard issues affect your ability to view stats and manage settings — but typically don't interrupt email delivery.

status.sendgrid.com (Official)
SendGrid's own status page. Updated by their engineering team during incidents. Can lag 10–20 minutes behind actual outages, especially for deliverability issues that take time to manifest in delivery data.
Check status.sendgrid.com →API Status Check (Independent)
Third-party monitoring that continuously pings SendGrid API endpoints and reports independently. Shows infrastructure issues even if SendGrid hasn't updated their own status page yet.
Check independent SendGrid status →X / Twitter
Search 'SendGrid down' or 'SendGrid not working' on X. Developers and email marketers report delivery failures in real time. Good signal for wide-reaching issues.
Search X for 'SendGrid down' →Test the SendGrid API directly
Make a test API call to the SendGrid mail/send endpoint. A 200 response with a message ID means SendGrid accepted the email — check your inbox to verify it was actually delivered.
curl -X POST https://api.sendgrid.com/v3/mail/send \
-H "Authorization: Bearer $SENDGRID_API_KEY" \
-H "Content-Type: application/json" \
-d '{"personalizations":[{"to":[{"email":"test@example.com"}]}],"from":{"email":"you@yourdomain.com"},"subject":"Test","content":[{"type":"text/plain","value":"Test"}]}'Check SendGrid Activity Feed
Log in to app.sendgrid.com → Activity. Filter by recent sends to see real-time delivery status. If recent emails show 'deferred' or 'bounced' en masse, you've identified the scope of the issue.

The most common mistake when emails stop arriving: assuming it's a SendGrid outage when it's actually a deliverability problem. Here's how to distinguish them:
"HTTP 202 Accepted (but no email arrives)"SendGrid accepted the email but delivery is delayed or filtered by the receiving inbox provider. Check Activity Feed for 'deferred' or 'spam report' events. This is NOT a SendGrid outage."HTTP 401 Unauthorized"Invalid or revoked API key. Not an outage — check your API key permissions at app.sendgrid.com/settings/api_keys."HTTP 429 Too Many Requests"You've hit SendGrid's rate limits for your plan tier. Not an outage — throttle your sending rate or upgrade your plan."HTTP 503 Service Unavailable"SendGrid API servers are temporarily unavailable. This IS a real outage signal — check status.sendgrid.com immediately."SMTP 421 / 450 / 451 (Deferred)"The receiving mail server is temporarily refusing the message. Often a spam filtering response, not a SendGrid issue. Check if your IP pool is on any blocklists."SMTP 550 (Hard bounce)"The destination email address doesn't exist or permanently rejected the message. Not an outage — remove hard bounce addresses from your list immediately."Activity Feed shows 'blocked'"SendGrid is blocking the email from sending — usually because the recipient previously unsubscribed or marked your email as spam. Not an outage — check your suppression list.SendGrid Outage History: What the Data Shows
SendGrid's infrastructure is generally highly reliable, but email deliverability issues (distinct from infrastructure outages) are more common and harder to diagnose:
True SendGrid infrastructure outages are relatively rare. The much more common problem is email deliverability degradation — emails accepted by SendGrid but filtered by Gmail, Yahoo, or other providers. Monitor both your API acceptance rate AND your actual inbox delivery rate to catch these. Check our SendGrid monitoring for current and historical uptime data.

If the API Is Returning Errors
- Confirm it's a SendGrid outage: check status.sendgrid.com
- Queue your emails locally — don't lose them, retry when service recovers
- For critical transactional emails, consider Mailgun or AWS SES as a fallback
- Implement retry logic with exponential backoff
- Alert your users proactively if time-sensitive emails will be delayed
If Emails Aren't Being Delivered
- Check Activity Feed for bounce and deferred event codes
- Test delivery to multiple inbox providers (Gmail, Yahoo, Outlook)
- Check if your sending IP pool is on a blocklist (MXToolbox)
- Review your domain authentication (DKIM, SPF, DMARC) settings
- Contact SendGrid support if you see widespread deferred events
Frequently Asked Questions
Where is the official SendGrid status page?
SendGrid's official status page is at status.sendgrid.com. It shows real-time status for the Email API, SMTP relay, Inbound Parse, Marketing Campaigns, and the SendGrid web dashboard. You can subscribe to email or webhook notifications for specific components.
Why are SendGrid emails not arriving but the status page shows operational?
Most SendGrid 'outages' are actually deliverability issues — SendGrid accepts and sends the emails, but they're filtered by Gmail, Yahoo, or other inbox providers. Check your SendGrid Activity Feed for bounce or spam report events. True infrastructure outages (API not accepting requests) are much rarer and appear on status.sendgrid.com within 15-20 minutes.
Does a SendGrid outage mean emails are lost?
Not necessarily. If SendGrid accepts your API call (HTTP 202), they've queued the email. During brief outages, queued emails typically deliver once service recovers. If the API itself is rejecting requests, you should queue emails in your own system and retry. SendGrid retains undelivered messages in their queue for a period before marking them as failed.
What's the best fallback when SendGrid is down?
For transactional email: Mailgun, AWS SES, and Postmark are the most common fallbacks. Many large senders use multi-provider strategies, routing different email types through different providers. At minimum, implement local email queuing so no sends are lost during brief outages.
How do I get alerts when SendGrid goes down?
Subscribe to email or webhook notifications at status.sendgrid.com, or use Better Stack / API Status Check Alert Pro to monitor SendGrid API availability. For comprehensive email monitoring, also track your own send rates and delivery rates — deliverability degradation often doesn't appear on SendGrid's status page.
