Q: Can I send a connection request without a message?
A: Absolutely! It's completely possible to send a connection request without including a message. Just leave the message box empty if that's what you prefer.
Why write a message?
Adding a personalized message can communicate that you are sincere about wanting to make a connection, and it can also give you an opportunity to stand out. Using clear language, try to explain why it would be mutually beneficial for you to be connected. Focus on how you can help the other person instead of asking directly for help or a job.
