How do I add attachments to my messages?

Video transcript:

Once you’re within the message editor it’s very simple to add an attachment to your message, all you need to do is click on the Paper Link icon right here, click Add Attachment and then search your computer of course for the file that you would like to attach. You can also attach more than one file to this particular message if you would like but overall the total size of all attachments combined cannot exceed 400 KB and that limit is placed on the attachments mainly for deliverability issues, to be able to insure a smooth deliverability we recommend keeping it under 400 KB for all attachments combined.
