Five Things You Need to Do Before Hitting Send on Your Next Email
Professional email communication is the backbone of modern business. Whether you’re reaching out to business contacts, following up with a new client, or sending an important email update to colleagues, one small mistake can have serious consequences. Unfortunately, once you hit send, there’s no taking it back.
Along with having a reliable email checklist before sending, professional communication tools like SendGuard can help prevent common email mistakes—such as replying to the wrong recipient, forgetting attachments, or sending sensitive information without protection.
Here are the top 5 checks to ensure your email makes the right impression:
1. Check the recipient: are you emailing the right person?
This is the most crucial step when writing a professional email. Sending sensitive company information to the wrong recipient can result in data breaches, legal issues, and damaged business relationships.
One major law firm once accidentally emailed a Wall Street Journal reporter that the SEC was investigating one of their Fortune 500 clients, causing massive reputational damage. Another company had to beg Google to delete an email containing trade secrets sent to the wrong inbox.
What to check:
- Check that the recipient’s name matches the intended person
- Verify the email address is correct
- Be especially careful with autocomplete suggestions
- For new contacts, confirm their email address through official channels
SendGuard users can utilize the recipient confirmation feature to add an extra layer of security before sending.
2. Check the email subject line — make your purpose immediately clear
Your subject line determines whether your email gets opened or ignored. Busy professionals receive dozens of emails daily, so your subject line must effectively communicate value and urgency.
Best practices:
- Keep it under 50 characters for mobile compatibility
- Include key information upfront
- Make it an actionable message when requesting something
- Use specific details rather than vague terms
- Avoid excessive use of exclamation points
Example: Instead of “Meeting,” write “Q4 Budget Review—Tuesday 2 PM Confirmation Needed“.
3. Check the content — review for professional tone and clarity
Your email content reflects your professional standards and the reputation of your company. Before sending any professional email, ensure your message is clear, concise, and error-free.
Content checklist:
- State your purpose in the first line
- Keep paragraphs to 2-3 sentences maximum
- Use bullet points for multiple items
- Maintain a professional tone throughout
- Include all the information the recipient needs
- Respect the recipient’s time with concise writing
Proofreading essentials:
- Check for spelling mistakes and grammatical errors
- Verify names, dates, and numbers are accurate
- Ensure the message format is professional
- Avoid slang and overly casual language
4. Check attachments and links — avoid errors and confidentiality breaches
Sending incorrect attachments or broken links can derail important business communications and potentially expose sensitive information.
What to verify:
- Attachment files are the correct versions
- File names are professional and descriptive
- Links direct to the intended destinations
- File sizes are reasonable for email delivery
- Sensitive documents are properly secured
The consequences of getting this wrong can be severe. For instance, Leicester City Council accidentally sent personal data of thousands of vulnerable people to 27 companies due to an attachment error—a costly mistake that led to a Data Protection Act investigation.
Pro tip: SendGuard’s attachment confirmation feature helps prevent these costly errors by requiring verification before attachments are sent. It provides you with an email security solution that helps you fulfil your data protection policy. It’s a great technique to get people to think about what they’re sending.
5. Check the greeting and signature — create a strong professional impression
Your email greeting and sign-off set the professional tone and provide essential contact information.
Greeting best practices:
- Use the recipient’s name when known
- Choose an appropriate formality level (employ a more formal greeting for new contacts)
- Examples: “Dear Mr. Smith,” “Hello Sarah,” “Good morning team“
Professional sign-off:
- Use appropriate closings: “Best regards,” “Kind regards,” “Thank you“
- Include your full name and job title
- Add complete contact information in your signature
- Include your company name and professional email address
Microsoft Outlook has already created some awesome signatures. To create your own Outlook signature, simply obtain the template, copy the preferred signature into your email message, and personalize it.
Additional email etiquette best practices
Beyond the top 5 essentials, here are important dos and don’ts when writing a professional email:
Email etiquette dos:

- Respond promptly: Acknowledge receipt within 24-48 hours
- Include context for new contacts: Explain how you got their information
- Keep formatting consistent: Use professional fonts and standard text sizes
Email etiquette don’ts:

- Don’t use excessive informal language or profanity: Unlike text messages, emails require more formality
- Don’t ignore CAN-SPAM requirements: If sending commercial emails, include a valid physical address, clear sender identification, truthful email subject lines, and easy unsubscribe options (violations can cost up to $46,517 per email)
