Here’s a message you can send to your client to confirm if you can use their name as a reference:
Hi
Thanks for connecting me with the owner of https://www.mymrmilk.co.uk. Before I reach out to him, I just wanted to check if you’re comfortable with me mentioning that I was referred by you. This will help in establishing trust and making the introduction smoother.
Please let me know if it’s okay to share your name as the referral source, and I’ll proceed accordingly.
Thanks again for your support!
Best,
Bloch
