Hi!

You could try with a follow-up.

Keep networking and leverage your School's alumni group!

Best,

Is there a reason why you want to talk to this specific partner. If so, state that on your e-mail (and your email would say something as "I am sorry for asking again for your time but I really wanted to talk with you specifically because of XYZ reason). 

If there is no reason to approach this specific partner, move on and approach someone else (even someone who is not a partner).

‘Cold-calling' via Linkedin usually is not a good approach at all. 

If you really want to connect with a partner from an MBB firm, the right way to do this is to leverage you network help you, i.e. you need to have someone introduce you. After all, consulting partner schedules are crazily busy and rest assured that they receive tons of unsolicited requests from all directions. 

• 1 follow-up as a gentle-reminder is generally acceptable - to float the mail to the top of their inbox.
• However, networking and cold mailing is statistics. You need to approach more people because it is a hit-rate thing.
• Cold mailing should be smart - try to figure out the focus areas of the person based on their LinkedIn profile. Try to customize your cold mails to bring out a connect in your profile and there's.
