Many email servers refuse to accept email attachments over a certain size.
While attachment sizes haven’t kept up with the times, there are other easy ways to send someone large files over email.
Even if you’re using a modern, online email client, message size is limited. Gmail, for example, allows messages to be up to 25 MB, including the message’s text and any attachments. Outlook.com allows only 10 MB. When sending messages over these services, they will automatically give you a helping hand and suggest alternatives—such as using Google drive for Gmail attachments and OneDrive for Outlook.com.
