Hi *|CONTACT.FIRSTNAME|*,

I hope you are doing awesome. It's been a while since we last caught up, and I've been keeping tabs on all the exciting things happening in the education sector, especially over at [Recipient's Institution].
Considering our shared passion for educational progress, it struck me that there might be some cool opportunities for collaboration. How about we catch up soon and chat about any new needs or challenges at your institution? I'd love to reconnect and explore some ideas. Could we pencil in a quick call or meeting in the next few weeks?

Thank you for considering my proposal. I look forward to the possibility of reconnecting.

Best regards,
[Your Full Name]
