You know this person well. Maybe it’s a boss you’ve worked with for years, a mentor who guided your career, or a colleague who became a friend. Now you need to write something formal—a resignation letter, a letter of recommendation, or even a sympathy note—and suddenly the blank page feels awkward. The words that come naturally in conversation don’t seem to fit on paper. You want to sound professional but also true to your relationship.

That tension is normal. It’s also why smart writers turn to a good letter template. Using a sample isn’t cheating. It’s a time-saving strategy that gives you a solid structure, the right tone, and useful phrases—while leaving room for your own voice. The best professional correspondence feels both polished and personal, and a well-chosen sample gets you there faster.

This guide is part of our Professional Correspondence series.

Why using a sample makes sense

A sample gives you a proven framework. You don’t have to worry about letter structure—where to put the date, how to format the salutation, what to include in the closing. Instead, you can focus on the content that matters: your specific message to someone you know well. Think of it as a map, not a script.

For example, if you’re writing a resignation letter to a boss who mentored you, a standard resignation letter sample will show you the necessary elements—notice period, transition help, gratitude—but you’ll need to add the personal touch. “Thank you for teaching me how to handle client calls” sounds far more genuine than “I appreciate the opportunities I’ve had.” A sample helps you avoid forgetting the formal parts so you can focus on the heartfelt ones.

How to choose the right sample for your situation

Not all samples are equal. A cover letter example for a corporate job won’t help you write a condolence letter to a friend who lost a sibling. Match the sample to the relationship and the occasion. Consider the formality level:

  • Formal: Letters to a boss, professor, or professional reference. Use standard business letter format, a formal salutation (e.g., “Dear Mr. LastName”), and a professional closing.
  • Semi-formal: Letters to a colleague you know well, a former teammate, or a neighbor. You can use first names and a warmer tone while still following letter writing etiquette.
  • Personal but structured: Sympathy notes, letters of recommendation for someone you know well, or thank-you letters. These require sincerity and specific memories.

If you’re writing a condolence letter to a distant relative, you might start with a letter template for sympathy but adapt it with a memory that only you share. That’s the sweet spot: structure from the sample, authenticity from you.

Adapting a sample without losing your voice

Take the skeleton of the sample—the opening, body, closing—and fill it with your own words. Pay special attention to the salutation and closing. A generic “Dear Sir” feels cold if you’ve shared coffee breaks for years. Use “Dear Alex” or “Hi Jamie” if the relationship allows. Similarly, your closing can be warmer: “With gratitude,” “All the best,” or “Warmly” instead of “Sincerely.”

Tailor the opening paragraph to grab attention quickly. Instead of “I am writing to inform you of my resignation,” try “It’s hard to know how to start this letter, but I wanted you to hear it from me first.” That honesty reflects your closeness. The sample gave you the structure; you provide the tone in writing.

Common mistakes to avoid

1. Using outdated language. “To whom it may concern” or “Please find enclosed” can make you sound robotic. Modern digital letter format is simpler. Write “I’ve attached” instead of “Enclosed please find.”

2. Ignoring format differences. A printed letter needs a physical letterhead design or your address at the top. An email uses a subject line and a signature block. Never copy a printed letter format into an email body—adjust the layout.

3. Skipping proofreading. A personal letter to someone you know well should still be error-free. Homophones (their/there) or typos can distract from your message. Always proofread your letter aloud or read it to a friend.

4. Over-relying on the sample. If the sample says “I am confident in my abilities,” but you want to say “I know I’ll do a great job because I already handle similar tasks,” change it. A customizable letter is one you make your own.

Real examples: When you know the recipient well

Imagine you need to write a letter of recommendation for a former employee who became a friend. A standard sample might say “John consistently exceeded expectations.” That’s fine, but you can add: “I remember when John stayed late to help a nervous client through a crisis—he didn’t ask for credit, he just solved the problem.” That specific story makes the endorsement powerful.

Or consider a sympathy note. If you’re writing a message for the loss of an uncle or aunt, the sample will give you the right phrases. But your own memory—“I’ll never forget how Uncle Mark taught me to fish at the lake house”—makes it personal. For help with that exact scenario, see our guide on sympathy messages for sibling loss.

Similarly, if you need to write a condolence letter for a distant relative, you can follow a letter template while adding a shared childhood memory. We have a dedicated guide to condolence letters for distant relatives that walks you through the balance.

Other situations include writing to a grandmother or a baby’s family. You’ll find practical help in our sympathy message for grandmother passing away and sympathy note for loss of a baby guides. Each sample is designed to be adapted to your specific relationship.

Final thought: Use the sample as a springboard

The best letters—the ones that feel professional and personal—start with a solid foundation and then get customized. Don’t worry about getting it perfect the first time. Write a draft, step away, then come back and tweak. The more you practice, the faster you’ll get at blending structure with your own voice.

Next time you’re staring at a blank page, grab a sample that matches your situation. Fill it with your words, your memories, your tone. That’s how you turn a generic template into a letter that feels like it came from you—and only you.
