In tech a lot of deals get done over email and text

Details get hashed out that way. But I've never seen a multi-million dollar deal closed anywhere but in the crypto space without at least a call, and much more often a video call.

Thats a multimillion dollar deal, not the intermediary for a hiring deal who gets a low %age.

You must not do a lot of large deals.

If a large deal ($25,000+), this is only the case with the largest tech companies (most customers would order $25k of Apple products online but not buy new expense management software without a call).

Yeah this is a backwards way to think about things. The vast majority of "deals" that I do on the buy side are done with significantly less friction than even email, and I place a high premium on that convenience. If every newsletter I subscribed to required a phone call to close the deal with me, none of them would have my business.

Yes but those are small deals. Most people will not buy a car or a house this way, although that is changing slowly.
