Todoist tip to link to Mac mail messages: You can create a script that exports your Mac mail message url to the clipboard, then you can paste it into Todoist as above. Unfortonately, Todoist doesn’t recognize these message:// urls as links (I tried the link format). However, if you drag the text over Mac Mail, it will open the associated email. Here is the script to save to ~/Library/Scripts/Applications/Mail/ (for more info see here):
tell application “Mail” set _sel to get selection set _links to {} repeat with _msg in _sel set _messageURL to “message://%3c” & _msg’s message id & “%3e” set end of _links to _messageURL end repeat set AppleScript’s text item delimiters to return set the clipboard to (_links as string) end tell
To copy the url you go into into a Mac mail message and click on the Scripts menu and choose whatever you named the file to, I named mine Clip URL.scpt.
Or better yet, go over and download Fast Scripts Lite like I did. I assigned this script to Cmd-Shift-M which made it even faster.
Now to just get the author of Todoist to enable recognition of these types of links.
