It is best practice to send out meeting minutes within one business day of the end of the meeting. If you wait too long, you risk people not reading it or your notes becoming outdated. E-mail is typically the best way to do it, especially with remote teams. Whether you type the meeting notes directly into the body of the e-mail or as an attachment will depend on what your notes contain. The benefit of having it all in the e-mail body is that those looking at your e-mail from their mobile devices will easily see the minutes without having to download the file and then find a good way to open the attachment.
Make use of colors and highlighting to point everyone to the important things in your minutes, namely the decisions made and the action items.
