Cold Calls vs Cold Email vs Cold Mail? What do you guys think

Our team did a fantastic job of pulling data after making over 250K+ cold calls The engagement rate was 3%. Doing 100 calls and getting 3 engagements is much faster and efficient than doing 100 emails. The first deal I closed in 2022, was via cold calls, and our first deal we closed at Caprae (~$20M EV) was via cold calls. While we do cold mail, cold email, LinkedIn outreach etc as well, cold calls by far has been the best. What do you all think Good luck searching y'all!
