Are There Limitations to the Size of Email Attachments?
Question
Is there a limit on the combined file size of the attachments sent to an Email connector's service account?
Environment
Answer
Most email providers have a limit on the combined file size of attachments. The exact file size limit varies by email provider, typically 25 MB or less.
| Email Provider | Size Limitation |
|---|---|
| Amazon Simple Email Service (SES v1) | 10 MB |
| Amazon Simple Email Service (SES v2) | 40 MB |
| Gmail | 25 MB |
| Outlook | 20 MB |
| Yahoo Mail | 25 MB |
If the files you need to share are greater than the size limit imposed by your email provider, do one of the following:
- Compress the files: Compressing files can significantly reduce their size.
- Split the files into multiple attachments: If you need to send a large file, you can split it into multiple attachments and send the attachments in separate emails.
- Use a different file connector.
