Sometimes when you design contact information for people, in say a grid, you stumble upon individuals that have very long e-mail addresses. You could solve this by using extra-large space for e-mail or shrink long texts, but that makes it usually visually unpleasing.
Instead, you could just use an anchor link that says "Mail", next to the name. The argument I hear against this approach is that some people wish to copy and paste the full e-mail address into their e-mail app.
Should one display the full e-mail address or just use an anchor link that says Mail? Is there any research on how inconvenient this approach is?
