A first day of work message needs to do something specific: it needs to land before the day does. That means it cannot be long, it cannot be generic and it definitely cannot sound like something scraped from a stock template. The best one sounds like it came from someone who actually knows the person and actually means it.
The 37 messages here were written for every tone and every relationship, warm and genuine for the person who needs encouragement, funny and light for the one who responds better to a laugh than a pep talk, personal and proud for the friend or family member who has been watching this moment build, and short and punchy for when you just need the right line quickly.

Final Thoughts
A first day message is one of those small things that lands bigger than it looks because it tells the person that someone was thinking about them at exactly the right moment. The right one takes ten seconds to send and stays with them all day.
