A quick hello and congrats on the [[achievement]]!

Hi {{first_name}},

It was great to meet you last night at the [[event name]]. I enjoyed our conversation afterward — particularly [[describe a specific aspect of the conversation]].

[[Provide something of value here]].

Stay in touch,

[[your name]]

Hi {{first_name}},

How are you? I can't believe it's been [[time frame]]! I just took a look at [[their site, recent work, blog, social media feed]] and [[brief but specific compliment]].

I am reaching out to see if you'd be interested in meeting up for another [[idea exchange/coffee chat/whatever term makes sense here]].I also would love to [[find something you can show them that may be of use to them]] that you might find useful as well—and of course use it as an excuse to catch up!

Hope all is well,

[[your name]]

Hey {{first_name}},

I'm just checking in to see if you had a chance to read my last email.

If you're open for a phone/video call on [[day proposed]], let me know!

Best,
