Issue
When adding and verifying a sender email address in your SendGrid account, you might encounter the error message:
Sender Not Verified
We were unable to verify your sender identity. Please resend the verification email and try again.
This error commonly occurs if you attempt to verify an email address that belongs to a domain not yet verified in your SendGrid account. For example, if your SendGrid account is set up and verified for company.com, but you try to add and verify user@example.com.

Cause
This error seems to be related to browser caching issues. Cached data or cookies might be causing issues with the verification process.
Resolution
- Try to validate the domain (in our example above "example.com"). You will need to send email verification in the Single Sender Authentication page, but clicking the link is no longer necessary if the domain is verified, the email should then become verified.
- Check Email Filters to ensure that your mail server or provider isn't blocking emails from sendgrid.net. Sometimes, domain-level filters or security tools like Mimecast, Proofpoint, or even Gmail’s strict settings may silently block or quarantine automated emails."
- Try the following steps if the above do not work:
- Clear your browser cache and cookies (for all time). For Google Chrome: chrome://settings/clearBrowserData
- Ensure you are using Google Chrome (our app is optimized for Chrome, Safari is ok, but Chrome is recommended)
- Make sure only one instance of the SendGrid account is being accessed at a single time. (Having multiple browsers logged into the same account can result in problems.)
- If you are using a VPN, retry while not using the VPN. Then:
- Login to your SendGrid account;
- Navigate to Settings > Sender Authentication and delete the e-mail previously added. Then add it again;
- Once you receive the new email, copy the verification link and open it in the same browser window and check it.
