A few people I need to work with—and a few friends—use email as their go-to communication tool. One CEO told me that he finds having only one way to write to be most efficient and refuses to use Slack. Prior to the pandemic some colleagues had Slack installed but seemed more comfortable in email. That’s changed. I have seen the pandemic push many people to more Slack and less email. Yay. For personal chat where we do not share a workspace, I prefer Keybase or WhatsApp or even Signal; I’ll use MMS or SMS if old-school texters insist. I have older relatives who have calcified on email, though. So fine. More and more I’m dropping notes to friends and family in subject lines and blasting them off. I put [chat] in the subject line once and decided it was redundant. Occasionally I’ll end with [EOM]. I’m still evolving my use of email. The medium is the message. Compare with AODLW.
