Use Grammarly to sharpen the words, then use Canva only if the letter needs a polished visual layout. A strong letter of interest wins because it sounds clear, warm, and specific. Pretty design helps, but only after the message is solid.
TLDR: Grammarly is best for fixing tone, grammar, and clarity. Canva is best for making the final letter look clean and professional. For example, a job seeker named Mia sent 12 letters of interest using a plain template and got 1 reply. After using Grammarly for tone and Canva for layout, she sent 12 more and got 4 replies. That is not magic, but a stronger letter can raise your odds.
What Is a Letter of Interest?
A letter of interest is a professional note you send to a company even when no job is posted. You are saying, “I like what you do, and I may be a strong fit.”
It is not the same as a cover letter. A cover letter answers a job ad. A letter of interest opens a door before the job ad appears.
Use it when you:
- Admire a company and want to work there.
- Met someone from the company at an event.
- Want to switch fields.
- Have skills the company may need soon.
- Want to build a warm contact before applying.
The goal is not to tell your full life story. Please do not. The goal is to make a busy person think, “This person is worth a quick reply.”
Canva vs Grammarly: The Simple Answer
Grammarly helps with the writing. It checks grammar, spelling, word choice, and tone. It can make a stiff letter sound more human. It can also catch the tiny mistakes your brain ignores after the third edit.
Canva helps with the look. It gives you templates, spacing, fonts, and visual polish. It is great when you want a PDF that looks neat beside your resume.
The catch is that Canva will not save a weak message. A beautiful letter that says nothing still says nothing. Honestly, Canva can also tempt you into adding too many colors, icons, and fancy fonts. Then your “professional letter” starts to look like a brunch menu.
When to Use Grammarly
Use Grammarly early. Write your rough draft first. Then paste it into Grammarly and check for:
- Clarity: Are your sentences easy to read?
- Tone: Do you sound confident but not pushy?
- Grammar: Are there typos or awkward phrases?
- Length: Are you rambling?
- Wordiness: Can 18 words become 9?
Grammarly is useful for lines like this:
“I am writing to express my deep interest in the possibility of contributing to your organization in a future role.”
That sentence is not awful. It is just sleepy.
A cleaner version is:
“I am writing to share my interest in future roles with your team.”
Shorter. Better. Less fog.
When to Use Canva
Use Canva near the end. After the words feel right, choose a simple letter template. Keep it clean.
Pick:
- One easy font.
- Black or dark gray text.
- White space.
- A small header with your name and contact details.
- A layout that matches your resume.
Avoid:
- Bright backgrounds.
- Tiny text.
- Three or more fonts.
- Huge decorative headers.
- Photos, unless your field expects them.
It drives me crazy that some Canva templates take a simple one-page letter and turn it into a design puzzle. You change one line, and suddenly the spacing jumps like it got scared. Expect to spend a few extra minutes fixing margins.
Other Helpful Tools
Grammarly and Canva are not the only options. A strong letter often needs a small tool stack.
- Google Docs: Best for drafting and saving versions.
- Microsoft Word: Great for formal formatting and PDF export.
- Hemingway Editor: Good for making sentences shorter.
- ChatGPT: Helpful for brainstorming, outlines, and rewrites.
- LinkedIn: Useful for researching the company and finding the right person.
- Jobscan: Helpful if you want to match skills to a field or role.
Do not let tools take over your voice. A recruiter can spot fake warmth from a mile away. Use tools to clean your message, not replace your personality.
A Simple Letter of Interest Sample
Here is a clean sample you can adapt. Keep it honest. Add real details. Remove anything that does not fit.
Subject: Interest in Future Marketing Opportunities
Dear Ms. Carter,
I am writing to share my interest in future marketing roles at BrightPath Health. I have followed your recent campaigns around patient education, and I admire how clearly your team explains complex health topics.
For the past three years, I have worked as a content marketing coordinator for a wellness startup. I have written email campaigns, blog posts, landing pages, and social content. One email series I managed raised trial signups by 28% over six weeks.
I would be excited to bring that mix of writing, research, and campaign support to your team. I know you may not have an open role right now, but I would be grateful to be considered for future opportunities.
I have attached my resume for your review. Thank you for your time. I would welcome the chance to connect for a brief conversation.
Sincerely,
Jordan Lee

Why This Sample Works
This letter works because it is specific. It names the company. It explains why the person cares. It gives one strong result: 28% more trial signups. Numbers help. They make your value easier to picture.
It also respects the reader’s time. No giant blocks of text. No desperate tone. No weird humble bragging.
A good letter should answer three questions fast:
- Why this company?
- Why you?
- What should happen next?
Quick Editing Checklist
Before you send your letter, run this checklist:
- Is it under one page?
- Is the greeting correct?
- Did you name the company?
- Did you include one clear achievement?
- Did you ask for a simple next step?
- Did you proofread the name, title, and email?
- Did you save it as a PDF?
If you can, read it out loud. This feels silly. Do it anyway. Your ears catch clunky lines your eyes skip.
Best Workflow for a Strong Letter
Here is a simple process that works well:
- Research the company for 10 minutes.
- Write a rough draft in Google Docs or Word.
- Use Grammarly to fix clarity and tone.
- Trim the letter until it fits one page.
- Use Canva only if you want a cleaner visual layout.
- Export as PDF and send it with your resume.
Final Tip
Grammarly is your editor. Canva is your stylist. Let Grammarly help you sound sharp. Let Canva help you look polished. But let your real experience lead the letter.
A strong letter of interest does not need drama. It needs focus. Show why you care. Prove you can help. Ask for a small next step. That is the whole game.
