it entirely depends on the topic. an example is realizing the queries will end up with multiple back and forths.

for a lot of things a phone call can solve something in minutes and it’s cleared from your brain queue. while some emails end up with back and forth waiting for each others responses. that’s can be hours or days where it sits in your brain as yet another task to manage. wasteful for something that could have easily been tied up with a quick phone call.
