Thank You Note to a Client for Selecting Our Services

By Shawn Gregoire, founder of Capstone Outreach · Updated October 2026

A thank you note to a client for selecting your services should thank them for the choice. Name the exact goal they hired you for, and tell them just what happens next. Example: 'Thank you for choosing us for [specific detail], [Name]. Next step: our kickoff call on [date].' The key is simple. Thanks plus a clear next step turns a signature into trust.

Doubt creeps in during the days right after a client signs. They've just spent money and taken a risk on you. A quick, personal thank you tells them they made a good choice. It does this before the first piece of work even arrives.

What makes it land is proof that you listened. Repeat the goal they described in their own words. Introduce the people they'll work with and say what the first week holds. Skip the brochure language and sign it yourself.

1. Client just accepted your proposal (email)

Subject: Thank you, and here's what happens next

Hi [Name], Thank you for accepting our proposal for [project]. We're excited to get started. You told us the main goal is [specific detail, e.g. cutting your month-end close from ten days to five], and that's what we'll measure ourselves against. Next steps: 1. Kickoff call on [date]. Calendar invite coming today. 2. [Team member] will send a short intake form by [date]. If anything comes up before then, reply here. Best, [Your name]

Why it works: Repeating their goal and listing next steps calms nerves after signing. It shows you were listening.

2. Small service business, new customer (email)

Subject: Thank you for choosing [Your company]

Hi [Name], Thank you for choosing [Your company] for [service]. We know you had other options, and we're grateful you picked us. Your appointment is set for [date and time]. [Technician name] will be there and will call about 30 minutes ahead. If you need to change anything, just reply or call [phone]. We look forward to taking care of you. Warmly, [Your name]

Why it works: Naming the person who will show up makes a new customer feel known before the first visit.

3. Quick text right after they sign (text)

Got your signed agreement, [Name]. Thank you for choosing us! [Team member] will reach out tomorrow to schedule kickoff. Really looking forward to working on [specific detail] together.

Why it works: A text within the hour confirms you got it. It keeps the warm feeling of the choice going.

4. Client chose you over a larger competitor (email)

Subject: Thank you for trusting a smaller team

Hi [Name], Thank you for choosing us for [project]. I know you also talked to some bigger firms, and I appreciate you taking a chance on a smaller team. Here's my promise: you'll always have my direct line, and you won't be handed off to someone who doesn't know your account. If you ever feel otherwise, tell me. Kickoff is [date]. Looking forward to it. [Your name]

Why it works: Naming the risk they took and making a firm promise turns your small size into a plus.

5. Introducing the team who will do the work (email)

Subject: Meet your team for [project]

Hi [Name], Thanks again for choosing us. I'd like to introduce the people you'll work with: [Team member 1], your day-to-day contact, who has run [specific detail] for clients like you. [Team member 2], who will handle [specific area]. I've copied them both here. I'll stay involved throughout, so you can always reach me too. Excited to get started, [Your name]

Why it works: Introducing named people with the right experience builds trust in the choice they just made.

6. New client who came through a referral (email)

Subject: Welcome, and thank you

Hi [Name], Thank you for choosing us for [service]. [Referrer name] spoke very highly of you, and I can see why after our conversations. We'll start with [first step] on [date]. Before then, it would help to have [specific item, e.g. last year's statements] if they're handy. We're glad to have you with us. Best, [Your name]

Why it works: Warmly naming the friend you share starts things off on shared trust.

7. Thank you letter for a long-term contract (email)

Subject: Thank you for selecting [Your company]

Dear [Name], On behalf of everyone at [Your company], thank you for selecting us as your [service] partner. We don't take a multi-year commitment lightly. Over the first ninety days, we'll focus on [specific detail, e.g. mapping your current process and fixing the reporting gaps you mentioned]. You'll get a short written update from me every two weeks. We're honored to earn your trust. Sincerely, [Your name] [Title]

Why it works: A formal tone with a clear ninety-day focus fits a large deal. It also puts their leaders at ease.

8. Text to a client you know personally (text)

[Name], thank you for trusting me with [specific detail]. It means a lot coming from you. I'll send the plan for the first two weeks by Friday.

Why it works: When the client is also a friend, a short personal text feels more natural than a formal letter.

9. First order from a new customer (email)

Subject: Thanks for your first order, [Name]

Hi [Name], Thank you for your first order with us. Your [product or service] is scheduled for [date]. Since you're new, here's one tip from customers who've been with us a while: [specific detail, e.g. book your next service before you leave, since spring slots fill early]. If anything isn't right, reply to this email and it comes straight to me. Thanks again, [Your name]

Why it works: A useful insider tip adds value to the thank you. It shows you care how things go after the sale.

10. Client chose you after a long decision process (email)

Subject: Worth the wait

Hi [Name], Thank you for choosing us. I know this decision took months and a lot of internal conversations, and I appreciate the care you put into it. To honor that, we'll start where your team was most concerned: [specific detail, e.g. data migration]. I'll share a plan for it by [date] so your stakeholders can see exactly how we'll handle it. Grateful to be working together, [Your name]

Why it works: Starting with their biggest worry rewards a careful buyer. It helps them defend the choice inside their company.

11. Handwritten card for the first week (card)

[Name], thank you for choosing us. It was a pleasure meeting you and hearing about [specific detail]. We're going to do great work together. [Your name]

Why it works: A paper card in the first week is so rare that clients often keep it on their desk.

What to avoid

After you send it

If you don't hear back within a couple of days, that's normal. Just make sure the first next step happens on time. Check in yourself after the first week to ask how things feel so far. Check in again at thirty days. After that, plan a short personal note or call at least once a month during an active project. Once the work is ongoing, do it every quarter. Then the client hears from you about more than work and invoices.

Building the habit: how to keep in touch with contacts and what a personal CRM does.

They signed. Now keep the first months warm. Set up a short plan for each new client: a welcome, a check at two weeks, another at one month. Capstone stops the steps the moment they reply.

A study of 20 million LinkedIn members found that acquaintances, more than close friends, led to new jobs (Science, 2022). Capstone keeps those people warm. You approve every message, and it goes from your own email or phone.

Frequently asked questions

How do you say thank you to a client?

Thank them for one clear choice or action, use their name and say what it means to you. For a new client: 'Thank you for choosing us for your office redesign, [Name]. We heard how much the new layout matters to your team, and we're excited to deliver it.' Then add the next step. Keep it short and send it fast.

What should a thank you email to a new client include?

It needs four things. Give a sincere thank you for choosing you and repeat their goal in their own words. List the next steps with dates, and give a direct way to reach you. Keep it under a page. A personal signature from the person who sold the work matters more than company branding.

Should I send a thank you email after a client accepts a proposal?

Yes, the same day. It confirms you got the acceptance, thanks them for the choice and lays out what happens next. Clients often feel a moment of doubt after they commit. A clear, warm email right away tells them they chose well.

Is a handwritten thank you note to a new client worth it?

For larger or long-term clients, yes. A short handwritten card mailed in the first week stands out, because almost nobody sends them anymore. Keep it to two or three sentences. Mention one personal detail from your talks and sign it yourself.

How soon should I thank a new client?

Thank them within hours of signing or placing the order. Do it no later than the next business day. Speed shows how quickly you'll respond for the rest of your time together. A slower, more personal touch like a card can follow later in the first week.
