Today, I have started the LinkedIn account and sending a connection request with an introduction message to the leads(Prospects).

Is this correct?

Your sentence should read:

Today I created a LinkedIn account and sent connection requests with an introductory message to the leads(Prospects)

Well done on your efforts!

Don't we say sending rather than sent in while use in today?
