I think also over-communicate with your Sales colleagues.
One message, one slack message, one email, one launch is not enough - do more than you would actually think is necessary because they've been very busy people.
They've got their own priorities, they're doing their own sales, they've got their own issues to deal with. So over-communicate and share success.
Success is contagious. People in Sales love to see success and so share successes, share early wins, share those milestones that you're going through on that journey with them, and you'll get them on board.
