SendGrid Attachment Size Exceeded

The total size of attachments exceeds the allowed limit.

Understanding SendGrid: A Powerful Email Communication API

SendGrid is a cloud-based email delivery service that provides reliable and scalable email solutions for businesses. It is widely used by developers to send transactional and marketing emails, ensuring high deliverability and detailed analytics. With SendGrid, you can manage email campaigns, track email performance, and handle email deliverability issues efficiently.

Identifying the Symptom: Attachment Size Exceeded

When using SendGrid, you might encounter an error indicating that the 'Attachment Size Exceeded'. This error typically appears when you attempt to send an email with attachments that surpass the allowed size limit.

Exploring the Issue: Why Does This Error Occur?

The 'Attachment Size Exceeded' error occurs because SendGrid imposes a limit on the total size of attachments that can be sent in a single email. This limit is in place to ensure optimal performance and deliverability. If the combined size of your attachments exceeds this limit, the email will not be sent, and you will receive an error notification.

Understanding SendGrid's Attachment Limits

As of the latest guidelines, SendGrid allows a maximum attachment size of 20MB per email. This includes the total size of all attachments combined. It's important to note that this limit may vary based on your SendGrid plan, so it's advisable to check the official SendGrid documentation for the most current information.

Steps to Fix the Issue: Reducing Attachment Size

To resolve the 'Attachment Size Exceeded' error, you can take the following steps:

1. Compress Your Attachments

Consider compressing your files to reduce their size. Tools like WinZip or 7-Zip can help you compress files into smaller archives, making it easier to stay within the attachment size limit.

2. Send Attachments in Separate Emails

If compression isn't sufficient, you can split your attachments across multiple emails. This approach ensures that each email remains within the size limit while still delivering all necessary files to the recipient.

3. Use Cloud Storage Links

Instead of sending large files as attachments, consider uploading them to a cloud storage service like Dropbox or Google Drive. You can then share the download links in your email, allowing recipients to access the files without exceeding attachment limits.

Conclusion

By understanding and addressing the 'Attachment Size Exceeded' error in SendGrid, you can ensure that your emails are sent successfully without interruptions. Whether by compressing files, splitting emails, or using cloud storage, these solutions will help you manage attachment sizes effectively. For more detailed guidance, refer to the SendGrid documentation.
