Email Attachment Size Limits
Attachment File Size limit:
In this article, you will learn the file size limit of the attachments you can add to an Email.
All email server providers limit the maximum email size that an email account can receive.
If you send an email that exceeds the maximum email size limit of the recipient’s email provider, your email will bounce off, and you will receive an email error back in your Conversations tab. Usually, you will receive one of the following error messages:
- “Attachment size exceeds the allowable limit”;
- “552: Message size exceeds maximum permitted”;
- “System Undeliverable, message size exceeds outgoing message size limit”;
- “The size of the message you are trying to send exceeds the global size limit of the server. The message was not sent; reduce the message size and try again”.
Mailgun supports a maximum message size of 25MB.
Note: You can't bypass the maximum size limit. However, if you need to send more files, You can upload the files to be attached to cloud storage servers (like DropBox, Google Drive, or SkyDrive) and include the download link in your email.
