SendGrid Status Monitor
SendGrid Status: Is SendGrid Down Right Now?
Use this SendGrid status guide to confirm outages fast, troubleshoot email delivery, API, SMTP, or template issues, and get real-time monitoring for the moment SendGrid goes down.
Quick SendGrid Status Checklist
- 1. Check official status updates.
- 2. Test API connectivity directly.
- 3. Verify with independent monitoring.
- 4. Check Activity Feed for errors.
Check the official SendGrid status page
SendGrid (a Twilio product) maintains a status page covering email delivery, API, SMTP relay, and dashboard health.
status.sendgrid.comTest API connectivity directly
Send a test API request to api.sendgrid.com/v3/mail/send with a valid API key. A 202 response confirms the API is operational.
SendGrid mail send API docsVerify with independent monitoring
Use API Status Check for third-party monitoring that verifies real endpoints and tracks historical incidents.
SendGrid on API Status CheckCommon SendGrid Issues During Outages
Emails not delivering or delayed
Transactional emails may be delayed or fail to deliver entirely during SendGrid infrastructure outages or IP reputation issues.
API returning 5xx errors
The SendGrid REST API may return 500, 502, or 503 errors when backend services are degraded, causing email send failures in applications.
SMTP relay connection failures
Applications using SendGrid SMTP (smtp.sendgrid.net on port 587 or 465) may fail to authenticate or connect during SMTP relay outages.
Email template rendering errors
Dynamic templates may fail to render or be sent with garbled content when the SendGrid template engine is experiencing issues.
Troubleshooting Steps Before You Assume SendGrid Is Down
- 1
Check the SendGrid status page
Visit status.sendgrid.com to see component-level status for email delivery, API, SMTP, and the SendGrid dashboard.
- 2
Verify your API key permissions
Ensure your SendGrid API key has the required Mail Send permission. An unauthorized API key returns 403 errors that mimic outage behavior.
- 3
Check your sender authentication
Domain Authentication (formerly Domain Whitelabel) must be configured correctly. Missing SPF or DKIM records cause delivery failures unrelated to outages.
- 4
Review the SendGrid Activity Feed
The Activity Feed in the SendGrid dashboard shows individual email events. Check for bounce codes or deferred delivery events to diagnose non-outage issues.
- 5
Test with a minimal API call
Send a minimal test email to a personal address via the API to isolate whether the issue is your code or SendGrid infrastructure.
Real-Time SendGrid Monitoring
API Status Check tracks SendGrid status with independent monitoring, uptime stats, and incident history so you can confirm outages quickly.
Independent SendGrid status checks
API Status Check performs independent monitoring so you can verify SendGrid status even if official updates are delayed.
Incident history and uptime data
Review recent incidents, response times, and reliability trends to understand SendGrid email delivery reliability.
Real-time alerts and integrations
Get notified with email alerts, RSS feeds, and webhooks when SendGrid experiences a new incident.
Alternative Solutions During SendGrid Outages
Switch to Mailgun or AWS SES temporarily
During extended SendGrid outages, Mailgun or Amazon SES can serve as drop-in email delivery alternatives with minimal code changes.
Queue emails for retry
Implement a message queue (SQS, RabbitMQ) to buffer failed email send attempts and retry them automatically when SendGrid recovers.
Use direct SMTP as fallback
Configure a fallback SMTP provider in your email library. Most email libraries support multiple SMTP configurations with automatic failover.
Monitor recovery via API Status Check
Set up alerts to get notified the moment SendGrid services recover from an outage.
Get notified when SendGrid is back up
No account needed. We will email you once and thats it.
SendGrid Status FAQ
Is SendGrid down right now?
Check status.sendgrid.com and API Status Check for independent monitoring. SendGrid provides component-level status for email delivery, API, and SMTP services.
Why are my SendGrid emails not delivering?
Email delivery failures can be caused by SendGrid outages, sender authentication issues, spam filter blocking, or bounced recipient addresses. Check the Activity Feed first, then status.sendgrid.com.
Why is SendGrid API returning 5xx errors?
5xx errors indicate server-side issues. Check status.sendgrid.com for active incidents and implement exponential backoff retry logic in your integration.
Why is my SendGrid SMTP connection failing?
SMTP failures can be caused by SendGrid relay outages, incorrect port settings, or authentication issues. Verify you are using port 587 with TLS and your API key as the password.
How long do SendGrid outages typically last?
Most SendGrid incidents resolve within 1–3 hours. Delivery delays during incidents are typically caught up automatically after recovery.
How can I get SendGrid outage alerts?
Subscribe to alerts on API Status Check to receive real-time notifications when SendGrid experiences an incident.
