I'm an Outlook user and as far as I know the # method of adding snippets is not supported by Outlook and only works when composing an email directly in HubSpot (not sure about Gamil).
To add a snippet in Outlook, I have to go via the Snippets option in the HubSpot Sales side bar.
Thanks Phil, I have triend this previously however as there are too many snippets in there from my company the one i need to use isnt in the top 12 or so on the list and I can't scroll down further to get other ones.
Do you know a way to get my snippet to be top of the list?
