Emails sent from BQE CORE have a maximum 15MB total message size, including the text and all attachments. If you attempt to add attachments larger than 15MB, you will encounter an error. When sending multiple attachments, you can reduce the message size by enabling automatic zipping of multiple attachments from Settings > Company.
Message and attachment size limits exist on all email services. This message size limit ensures your recipient's email service can receive the email and attachments properly.
