Need help on the Podcast.

Hi IH,

I am running a newsletter which covers the latest trends, developments and research on the Indian startup ecosystem.

I have started a podcast to discuss all these insights in-depth and I want to invite an Investor/VC to discuss these ideas with and let him share his experience on the same.

Long story short. I am looking for help on below points.

How do I approach them without being desperate and spammy?
How did you invite your first guest on your podcast?
Do I need to big before forwarding such requests?
Should I share my script/content beforehand in the introduction email?

Some advice on the email format and pitch would be really helpful.

Thank you.
