Staging:

Cause
SendGrid has a system limitation of 30Mb size for email. It is recommended that you do not use attachments that exceeds 10Mb. See Sending Attachments in SendGrid documentation for more infomation.
Workaround
- Do not use attachments higher than 6Mb or 10Mb.
- Consider the use of a remote SMTP server on your Adobe Commerce instance. For steps, refer to Configure email communications in our Admin Systems Guide.
- Reconfigure your server so that files can be saved within your module, and then attach the link to the files in the emails.
