Comprehensive troubleshooting guide to resolve Roadrunner email sending issues on all devices. Get your emails delivered instantly!
Understanding the problem is the first step toward a solution. Roadrunner email (also known as Spectrum Email) is a reliable service, but sending issues can occur due to various technical reasons.
When your Roadrunner email stops sending messages, it can disrupt both personal and professional communication. This problem typically manifests in several ways:
These issues can occur on any device - Windows PC, Mac, iPhone, Android, or through webmail. The good news is that most sending problems can be resolved with the proper troubleshooting techniques.
Roadrunner email uses the SMTP (Simple Mail Transfer Protocol) to send messages. When you hit "send," your email client connects to Roadrunner's SMTP server using specific settings for authentication and encryption. Any disruption in this process can prevent your emails from being delivered.

Advanced solutions for persistent sending problems
Many ISPs block port 25. Ensure you're using port 587 for SMTP. Test with Telnet: telnet mail.twc.com 587 should return a successful connection.
If authentication fails, reset your password via Spectrum account. Enable "Allow less secure apps" if using third-party clients.
Verify your IP isn't blacklisted using MXToolbox. If blacklisted, contact your ISP for a new IP address.
For business accounts, ensure proper SMTP relay configuration. Use "smtp.spectrum.net" with port 465 for SMTP relay.
Update your email client to support modern encryption. Disable old SSL protocols and enable TLS 1.2+.
Increase SMTP timeout to 2 minutes in your email client settings to accommodate network delays.
Common questions about Roadrunner email sending issues
Emails stuck in Outbox usually indicate a connection problem with the SMTP server. This can be caused by incorrect settings, authentication failures, internet connectivity issues, or server problems. Verify your SMTP settings, check your internet connection, and ensure you have authentication enabled.
Check Spectrum's official service status page or third-party outage monitoring sites like Downdetector. You can also try accessing webmail.spectrum.net - if you can't log in, there may be a service outage. Spectrum typically posts updates on Twitter @Ask_Spectrum during major outages.
This common problem usually indicates an SMTP configuration issue. Receiving uses IMAP/POP3 protocols while sending uses SMTP. Verify your outgoing server settings, port configuration, and authentication. Firewalls often block outgoing SMTP connections, so temporarily disable security software to test.
This error means your email client isn't properly authenticating with Roadrunner's SMTP server. Go to your account settings and ensure: 1) "Authentication required" is checked, 2) Your username is your full email address, 3) Your password is correct, and 4) You're using the correct SMTP server address.
