You need a testimonial for your LinkedIn profile, your portfolio, or a job application — and you know exactly which past colleague would write a glowing one. But asking feels awkward. Will they have time? Will they remember you well enough? Will they think you're being pushy? Writing a polite email to ask for a testimonial from a past colleague is a subtle art: it requires balancing gratitude with a clear, low-effort request. The right wording can turn a busy colleague into an enthusiastic endorser. This guide breaks down the common mistakes, optimal timing, and proven templates to help you get a thoughtful testimonial without burning any bridges.
Why a Well-Written Request Makes All the Difference
Your past colleague's testimonial can be a powerful asset — it provides social proof of your skills, work ethic, and character. But if your request is vague, demanding, or poorly timed, they might decline or produce a generic, unhelpful response. A polite, specific request shows respect for their time and makes it easy for them to say yes. It also sets the tone for the content they'll write: if you guide them toward specific projects or traits, you'll get a much more meaningful testimonial than if you just ask for "a few words."
Key takeaway: A thoughtful request is an investment in a stronger testimonial — and a stronger professional relationship.
Common Mistakes That Can Sink Your Request
Even with good intentions, many requests for testimonials fail or result in mediocre responses. Avoid these pitfalls to increase your chances of getting a glowing, specific recommendation.
- Being too vague. Saying "Could you write me a testimonial?" without any context leaves the colleague guessing what to say. They'll likely write something generic or put it off indefinitely.
- Asking too many people at once. Mass requests feel impersonal and reduce the likelihood of a thoughtful response. Choose 2-3 key people and personalize each request.
- Not giving a deadline. Without a timeframe, your request will drift to the bottom of their inbox. Provide a reasonable deadline (e.g., two weeks) to create urgency without pressure.
- Forgetting to make it easy. Asking for a testimonial without offering specific prompts or examples is like asking someone to write a book report without a book — they won't know where to start.
- Using a demanding or entitled tone. Phrases like "I need this by Friday" or "This is really important for me" can come across as pushy. Always frame it as a favor, not a requirement.
Choosing the Right Timing for Your Request
Timing can make or break your testimonial request. Send it too soon after you left the company, and they might not have had enough distance to reflect on your contributions. Send it too late, and they may have forgotten specific details. The sweet spot is 1 to 3 months after you've moved on. At this point, your work is still fresh enough to remember, but you're no longer a daily presence, which gives them perspective.
Also consider their workload. Avoid month-end, quarter-end, or major project deadlines. Tuesday or Wednesday mornings are generally best for sending. And if you know they're on vacation or parental leave, wait until they return — your request will be better received when they're not overwhelmed.

[Your Name]Checklist for a Successful Testimonial Request
Use this checklist before hitting send to ensure your request is professional, considerate, and effective.
- Choose the right person – someone who worked closely with you and has a positive impression.
- Personalize the email – reference specific projects, skills, or memories.
- Make it easy – provide prompts or bullet points to guide their writing.
- Give a clear, reasonable deadline – about two weeks is standard.
- Respect their time – keep it short, offer to decline gracefully.
- Proofread – a typo or unclear sentence can undermine your professionalism.
- Follow up once if needed – a gentle reminder after 5-7 days is acceptable; more than that is pushy.
If they agree, send a thank-you note immediately after you receive the testimonial — and if you publish it, let them know and offer to return the favor.
What to Do If You Don't Get a Response
Silence doesn't necessarily mean "no." People get busy. Here's how to handle it professionally.
- Wait 5-7 business days before sending a brief, polite follow-up. Example: "Just circling back on my previous message — no pressure at all, but if you're still open to writing a testimonial, I'd be grateful."
- If you still get no response after one follow-up, assume they're either too busy or uncomfortable. Don't send a third email — it crosses into harassment.
- Consider asking someone else. You don't need a testimonial from every colleague; 2-3 strong ones are enough.
- If they decline, thank them for considering it and move on. A graceful exit preserves the relationship.
Key takeaway: A non-response is not a personal rejection. Respect their silence and focus on the colleagues who are able and willing to help.
Frequently Asked Questions
Q: Should I ask for a testimonial via email or LinkedIn's recommendation feature?
A: Both are fine, but an email is often more personal and allows for a longer, more detailed request. You can ask via email and then, if they agree, send a LinkedIn recommendation request as a follow-up. However, some people find the LinkedIn feature easier because it's structured. Choose what feels more natural for your relationship.
Q: How long should a testimonial be?
A: 100-200 words is typical for a professional testimonial. It should be concise but specific — mentioning skills, contributions, and impact. If you give prompts, they'll naturally hit the right length.
Q: Can I ask for a testimonial from someone I haven't spoken to in years?
A: Yes, but you'll need to reconnect first. Send a warm "catch-up" email before making the request, or mention something you've seen about them recently. Don't lead with the ask — re-establish the relationship first.
Q: What if I want to use the testimonial for a job application, not LinkedIn?
A: Specify that in your request. You can ask for a more formal letter or simply a paragraph you can quote. Give them context about the role or industry so they can tailor their language.
Q: Should I offer to write a draft for them to edit?
A: Some people appreciate that, others find it presumptuous. It's usually safer to provide prompts (like bullet points) rather than a full draft. Let them write in their own voice — it will sound more authentic.
