Hey {{ Name }},
I just tried giving you a ring — bad timing, I guess! I’m {{ Your Name }} from {{ Your Company }}, and I wanted to chat about how me might help you with {{ Problem or Opportunity }}.
Can we try setting a time that works better for you? How about {{ Date #1 }} or {{ Date #2 }}? Or just let me know when you’re free to talk.
Hope to catch you at a better time soon!
Best,
