SendGrid is a cloud-based email delivery service that provides reliable transactional email delivery, scalability, and real-time analytics along with flexible APIs that make custom integration easy. It is widely used by developers and businesses to send marketing and transactional emails.
One common issue users encounter with SendGrid is the 'Bounced Email' problem. This occurs when an email cannot be delivered to the recipient's server and is returned to the sender. This can affect email deliverability and user engagement.
When an email bounces, SendGrid provides a bounce code that indicates the reason for the failure. Common bounce codes include:
For a comprehensive list of bounce codes, refer to the SendGrid Bounce Codes Documentation.
Bounced emails can occur due to various reasons such as:
Log into your SendGrid account and navigate to the Email Activity page. Here, you can view detailed information about each bounced email, including the bounce reason and code.
Ensure that the recipient's email address is correct and active. You can use email verification tools to validate email addresses before sending.
If the bounce reason indicates an issue with the recipient's server, contact the recipient to ensure their server is operational and not blocking emails from your domain.
Ensure your email content complies with anti-spam policies. Avoid using spam-triggering words and ensure your domain's SPF, DKIM, and DMARC records are correctly configured. For more information, visit SendGrid's SPF, DKIM, and DMARC Guide.
By understanding the reasons behind bounced emails and following these steps, you can improve your email deliverability and ensure your messages reach their intended recipients. Regularly monitoring your email activity and maintaining a clean email list are key practices for successful email communication.
