Hi {{first_name}},
You [[specific action: downloaded our guide, attended our webinar, visited our pricing page]] about [[timeframe]] ago, and I wanted to circle back. Things might have shifted since then.
If [[the original challenge]] is still on your radar, I'd like to pick up where we left off. If it's not, no worries at all.
Would a 15-minute call this week make sense?
