If you’ve ever ended an email with “Let me know if you need more information,” please stop.

We add that phrase to sound polite and helpful. We think we’re encouraging people to ask more questions and seek out what they need. We expect it to add value.

But in reality, it doesn’t. 

It often creates more work than it saves. Instead of closing loops, it opens them. When you put the burden on the other person to ask for more info, you’ve created a second step. They have to read your message, figure out what’s missing, send a reply, then wait for you to respond again. It slows down decisions, adds ambiguity, and makes collaboration harder than it needs to be.

Instead, ask yourself:
“What additional information might they need after they read my email?”.
And then provide that information. 

Over-communicate upfront.
  - Share the context, not just the conclusion.
  - Provide the backing data, not just the summary.
  - Include the attachments or links you know they’ll ask for.
  - Clarify next steps and deadlines.
  - CC the person that might need to respond next.

It’s not about writing long emails. It’s about writing complete ones. Complete messages save time, reduce back-and-forth, and build trust, because people know they can rely on you to give them what they need to move forward.

Next time you’re about to type “let me know if you need more information,” pause and ask yourself: 
 What would they need to know to act right now?
Then give them exactly that.

Because communication isn’t just about sharing. It’s about making it easier for others to succeed.
