Copy and pasting email addresses always inserts ‘mailto:email@email.com’ in the address field

If Barney's solution still isn't there for you, then here is a brief AppleScript that strips the mailto: prefix from the mail address:

1. Launch Script Editor from Dock : Launchpad : Other.
2. Copy/paste the following AppleScript code into the Script Editor
   1. Click the hammer (compile) button
   2. Click the Run button
   3. Copy/paste the mail address into the first dialog as shown in the above screen capture
3. You can save the AppleScript as Format: Application to your Desktop and double-click it to run.

Code

-- email_addr.applescript

-- strip mailto: string from web mail address and present selectable address in dialog
use scripting additions

set orig_address to text returned of (display dialog "Enter source email address:" & return & "(e.g. mailto:magoo@example.com)" default answer "")

if orig_address contains "mailto:" then
	display dialog (do shell script "sed -e 's/^mailto://' <<<" & orig_address)
else
	display dialog "mail address already in expected format" giving up after 15
end if
return



If you are copying the URL instead of the email address (because somebody embedded into their email address), then that's what you are getting.

If you just click on the email address instead of copying the URL, it will open a new message with just the email address.
