Calls can be more effective than emails but also more risky. You kinda just have to go for it.

You still want to hit the same points as the email:

<aside> 💡 Structure:

• Self Introduction
• Team Introduction
• What we do
• How we can collaborate
• Thanks and footer

Notice three key points:

• We are a 501(c)(3) non-profit.
• We do competitive robotics and run educational programs.
• Call-to-action to setup a meeting </aside>

Be polite and professional. The most important thing is to set up a potential meeting time. After the call, immediately send an email with the meeting details.
