How to know if you sound aggressive without meaning to

A practical method for figuring out whether your written communication is coming across as more intense than you intend — and what specific habits create that effect.

Updated April 29, 2026 · By the DeftBrain team

A coworker told you recently that your Slack messages 'come across kind of intense.' You were surprised. You did not feel intense when you wrote them. You went back and reread the messages, and you could not see what they were talking about. The messages looked normal. They looked like communication. And yet, here was a person you trust telling you that you sound aggressive, and you had to take that seriously. You are not unusual. Many people who do not feel aggressive in person come across as much sharper in writing than they realize. The gap is real, and it is fixable, but only if you can see what is creating it.

Here is how to figure out whether your messages are landing harder than you mean, and what specific habits cause it.

How to do it
1

Read your messages out loud in someone else's voice

When you read your own writing in your head, you supply the tone — friendly, neutral, warm. The reader does not have your tone. They supply their own, which is often more anxious, more guarded, more ready to perceive criticism. Read your last five Slack messages aloud in a flat, neutral tone, the way a stranger might. Does anything land sharper than you intended? That is what your colleagues are reading.

2

Count your imperative verbs

Imperative verbs — do this, send that, fix this, look at — read as commands, even when you mean requests. A message full of imperatives reads as a list of orders. The fix is to add a frame: 'could you,' 'would you mind,' 'when you get a chance.' These are not weasel words. They are the verbal equivalent of a friendly tone of voice. You probably use them automatically in person and skip them in writing because writing feels efficient. Efficient often reads as harsh.

3

Notice if you start messages with 'so' or 'actually'

Both of these are tonal markers that pre-load the message with disagreement. 'So, about the report' sounds like a problem is coming. 'Actually, I think' sounds like you are correcting them. You may mean neither. But the reader is bracing before they finish the second word. Just dropping these openers makes most messages read significantly warmer.

4

Watch how you give negative feedback

If you send 'this section is wrong' or 'we cannot do it this way,' the reader receives: I am being criticized, possibly attacked. If you send 'I think this section might be off — want to walk through it?' the reader receives: I have a concern and want to collaborate. Same content. Wildly different vibes. Negative feedback is where the aggression-without-meaning-to most often shows up. The cost of softening is one extra sentence. The cost of not softening is the colleague who tells someone else you are intense.

5

Run your writing through something that has no dog in the fight

Your own ear cannot detect the pattern, because your own ear has the intent baked in. Paste a sample of your messages — emails, Slack, texts — into a tool that just reads the writing without context, and see what it tells you. If it identifies you as intense, terse, or commanding when you thought you were warm and helpful, that is the gap. The first step to closing the gap is seeing it exists.
