5 Email Mistakes That Make Your Business Look Amateur

Nobody tells you. That’s the worst part. Clients won’t say “your email looks unprofessional.” They’ll just quietly choose someone else. Here are five email mistakes I see Kigali business owners make constantly — and they’re all fixable in an afternoon.

1. Using a personal email for business

We’ve covered this in depth elsewhere, but it bears repeating: [email protected] is not a business email. It’s a personal account with a business name crammed into it. Clients notice. Procurement departments flag it. Spam filters are more suspicious of it.

Fix: Get a domain. Set up [email protected]. Time: 15 minutes. Cost: less than your weekly data bundle.

2. Mismatched sender names

Your email says “From: Babe Girl” but you’re sending a business proposal. This happens more than you’d think — people set up their Gmail years ago with a nickname and never changed it. Now every business email they send arrives from a name that belongs on a dating app.

Fix: Go to your email settings and change your display name to your actual name or your business name. Takes 30 seconds.

3. No email signature

You send a quote and the client wants to call you. They scroll down. Nothing. No phone number, no website, no address. They have to go hunting through old messages or Google your company. Most won’t bother.

Fix: Add a simple signature with your name, title, phone number, and website. Not a wall of text with inspirational quotes and five social media icons — just the basics.

4. Sending attachments without context

“Please find attached.” That’s the entire email. Attached is a file called “Final_FINAL_v3 (2).pdf.” The client opens it and gets a quote with no cover note, no explanation of pricing, no next steps. Professional? Not quite.

Fix: Always introduce your attachment. One paragraph explaining what it is, what the key numbers are, and what you need from the client. Make their life easy.

5. Replying from a different email

The client emails your business address. You reply from your personal Gmail because it’s more convenient on your phone. Now the thread is split across two email addresses, the client is confused about which one to use, and your business email looks like a facade.

Fix: Set up your business email on your phone. Every provider supports mobile access. If you use Google Workspace, it’s literally the Gmail app with a second account added.

None of these are difficult fixes. Each one takes less time than scrolling through Instagram. But together, they’re the difference between a client thinking “this company has it together” and “I’m not sure about these guys.”
