Why grammar matters in emails
Email is often the first — or only — written impression you make. A message full of grammar errors to a hiring manager, new client, or senior colleague suggests carelessness, even when the underlying idea is solid. This isn't about rigid grammar rules for their own sake. It's about clarity: grammatically correct writing is easier to read and harder to misunderstand. And in professional contexts, looking like you took care over your words matters because it signals you take care over your work.
The stakes vary by situation. A quick Slack message to a teammate is forgiving. An email to a client, a job application, a complaint to a vendor, a message to your landlord — these carry more weight. The few seconds it takes to run a grammar check before hitting send is almost always worth it.
Common email mistakes an AI grammar checker catches
✗ "Their are several issues we need to address."
✓ "There are several issues we need to address."
Homophone confusion — their/there/they're is one of the most common errors spell check misses entirely.
✗ "The team have reviewed the proposal and we think it's alright."
✓ "The team has reviewed the proposal, and we think it looks good."
Subject-verb agreement and informal word choices that reduce professionalism.
✗ "I wanted to follow up regarding the meeting we had discussed it last Tuesday."
✓ "I wanted to follow up regarding the meeting we discussed last Tuesday."
Redundant phrasing that creeps in when writing quickly without review.
✗ "Please find attached the report, it contains the figures you asked about."
✓ "Please find the attached report, which contains the figures you requested."
Comma splice and word-order issues that appear in rushed emails.
Why AI catches what spell check misses
Standard spell check catches misspelled words — words that don't exist in the dictionary. But most grammar errors in emails aren't misspellings; they're correctly-spelled words used in the wrong place. "Their" and "there" are both in the dictionary. "It's" and "its" are both valid words. A comma splice is two grammatically correct halves joined wrong. AI grammar checking understands context and meaning, so it identifies these errors the same way a human proofreader would — by reading the sentence and understanding what it's trying to say.
