I’ll Let You Know: 60 + Best Responses to Follow-Up

There’s a special kind of silence that lives right after someone says I’ll let you know. Not loud. Not dramatic. Just… hanging there, blinking slowly, daring you to overthink. Is it a yes in pajamas. A no in disguise. A maybe that forgot its shoes. This phrase shows up everywhere—texts, emails, meetings, voice notes you replay twice for tone. And suddenly you’re stuck choosing between patience and plotting a follow-up that doesn’t scream I’m spiraling.
