When you leave a job, saying goodbye to coworkers is the easy part. You’ve shared lunches, meetings, and the occasional office crisis. A warm note to them almost writes itself.
Saying goodbye to clients is different.
Clients aren’t just people you like working with. They’re relationships your company depends on. They pay the bills. And while you may have spent years building trust with them, those relationships technically belong to your employer, not to you. That makes a goodbye email to clients one of the trickiest messages you’ll write on your way out.
Write it well, and you leave clients feeling reassured, grateful, and confident in whoever takes over. Write it carelessly, and you can worry a client into leaving, upset your employer, or even break the terms of your employment contract.
This guide walks you through exactly what to include, what to leave out, how to avoid overstepping, and how to adapt your message to different situations, with templates you can use.
First, Understand Why Client Goodbyes Are Different
Before you write a word, it helps to understand what’s at stake for each person involved.
For your client, your departure raises questions and sometimes a little anxiety. Who’s going to handle my account now? Will they know my history? Will my project be delayed? Is something wrong at this company? A client who has relied on you for years may feel a real sense of loss, and some will quietly wonder whether it’s time to look elsewhere.
For your employer, your departure is a risk. When a client-facing employee leaves, the company worries about losing the relationship, especially if the client liked you personally. That’s why many companies have rules about who contacts clients, when, and what gets said.
For you, the goodbye is about your reputation. The way you exit tells clients (and your former employer) exactly what kind of professional you are. People remember whether you left them in good hands or left them hanging.
A good client goodbye email serves all three: it reassures the client, protects the company relationship, and leaves your reputation stronger than before.
The Golden Rule: Talk to Your Manager Before You Email Any Client
This is the most important step, and the one people most often skip.
Never contact clients about your departure until your manager has approved it. Here’s why:
- Your company may want to control the timing. Many employers prefer to announce departures themselves, often after a replacement has been chosen, so clients hear the news and the solution at the same time.
- Your company may want to send the message itself. Some firms have the account manager or a senior leader write to clients, or send a joint email from you and your successor.
- Your contract may restrict you. Many employment agreements include confidentiality, non-solicitation, or non-compete clauses. A non-solicitation clause typically means you can’t encourage clients to follow you to your next job. Even an innocent-sounding line in a goodbye email could be seen as crossing that line.
- It protects you. If your employer approves the message and the timing, no one can later claim you tried to take clients with you.
Ask your manager directly: “How would you like me to handle telling my clients? Should I reach out, or would you prefer to announce it?” Then agree on who sends what, when, and who the client should contact going forward.
A quick note: this article offers general professional guidance, not legal advice. If you signed a non-compete or non-solicitation agreement, or you’re joining a competitor, read your contract carefully and consider talking to an employment lawyer before contacting any clients.
What to Include in a Goodbye Email to Clients
A strong client goodbye email is short, clear, and focused on the client’s needs, not your next adventure. It usually includes six elements.
1. A clear announcement. Say plainly that you’re leaving and when your last day is. Don’t bury it in the third paragraph.
2. Genuine thanks. Thank them for the relationship. If you worked together for a long time, mention something specific: a project you’re proud of, a challenge you solved together, or simply how much you enjoyed working with them.
3. Who’s taking over. This is the most important part for the client. Name your successor, give their role, and include their contact details. If you can, say something that builds confidence in them: their experience, their familiarity with the account, or the fact that you’ve briefed them thoroughly.
4. Reassurance about continuity. Tell the client what happens to their work. Is the project on track? Has your successor been briefed on their history and preferences? Clients want to know nothing will fall through the cracks.
5. What happens next. If there’s a handover meeting or introduction call, mention it. If there’s anything urgent the client should raise before your last day, invite them to.
6. A warm, professional close. Wish them well. If your company allows it and it’s appropriate, you may share a way to stay in touch, like LinkedIn. More on the rules for that below.
What Not to Say: How to Avoid Overstepping
This is where most client goodbye emails go wrong. Your intentions may be good, but some lines can worry clients, upset your employer, or create legal trouble. Avoid these.
Don’t invite clients to follow you. Lines like “If you ever need help, you know where to find me,” “I’d love to keep working with you at my new company,” or “Feel free to reach out to me directly for anything” can look like solicitation. Even if you don’t mean it that way, your employer may read it that way. If you’re under a non-solicitation agreement, this is the line you’re most likely to cross by accident.
Don’t share your new employer unless you’ve been cleared to. If you’re joining a competitor, naming them in a client email is especially risky. Even if you’re not, some companies prefer you don’t mention where you’re going. If your manager is fine with it, a short mention is okay. If you’re unsure, leave it out.
Don’t explain why you’re leaving in detail. Clients don’t need your reasons, and anything negative (“the workload became unmanageable,” “leadership has changed a lot lately”) plants doubt about the company. A neutral line such as “I’ve decided to take on a new opportunity” is plenty.
Don’t criticize the company, your team, or your successor. Not even gently, and not even as a joke. “They’ll do their best to fill my shoes” sounds modest but quietly suggests your successor isn’t as good. Every word should build confidence, not chip away at it.
Don’t overpromise. Avoid lines like “Nothing will change” or “Your project will be finished on time, guaranteed” unless you’re certain. You won’t be there to make sure it happens, and your successor may inherit a promise they can’t keep.
Don’t share confidential information. Don’t mention internal changes, restructuring, pricing plans, other clients, or anything the client wouldn’t normally know. A departure email isn’t the place for insider context.
Don’t make it about you. A paragraph about your exciting new role, your big move, or your plans for the future shifts the focus away from what the client actually cares about: their account.
Don’t send it from a personal email address. Always send it from your work account, with your manager’s approval. Emailing clients from a personal address, especially after you’ve left, is a serious red flag for employers.
Don’t copy your client list. This isn’t about the email itself, but it’s closely related. Taking client contact lists, files, or notes with you when you leave can breach your contract and confidentiality obligations, even if you built those relationships yourself.
Choosing the Right Timing
Timing shapes how clients feel about the news.
Wait until your successor is confirmed. Clients react much better to “I’m leaving, and here’s who will take care of you” than to “I’m leaving, and we’ll let you know who’s next.” If your company hasn’t chosen a replacement yet, consider waiting, or have your manager send the announcement once they have.
Give enough notice. Ideally, tell clients one to two weeks before your last day. That gives time for an introduction call with your successor and for the client to raise any open questions while you’re still around.
Don’t send it on your last afternoon. A message that arrives hours before you log off for good gives the client no chance to reply, ask questions, or meet your replacement. It can feel abrupt and leave them uneasy.
Call your most important clients first. For long-standing or high-value clients, a phone or video call before the email is a thoughtful touch, as long as your manager approves. The email then follows as a written confirmation with your successor’s details.
Subject Lines That Work
Your subject line should be clear without being alarming. Avoid anything that sounds like bad news for the client, like “Important Account Change” or “Urgent Update.”
Good options:
- Update on your account contact at [Company]
- Introducing your new contact at [Company]
- A personal note and a new point of contact
- Thank you, and an introduction to [Successor’s Name]
- Transitioning your account to [Successor’s Name]
Notice that most of them focus on the introduction, not the goodbye. That’s intentional. It keeps the client’s attention on continuity rather than loss.
Goodbye Email Templates for Clients
Adjust the details to fit your situation, and always get your manager’s approval before sending.
1. The Standard Client Goodbye
Use this for most client relationships.
Subject: Introducing your new contact at [Company]
Hi [Client Name],
I wanted to let you know that I’ll be leaving [Company] on [date]. It’s been a real pleasure working with you over the past [time period], and I’m grateful for the trust you’ve placed in me and our team.
Starting [date], [Successor’s Name] will be your main point of contact. [He/She/They] has been with [Company] for [time] and has worked closely with me on your account, so [he/she/they] is already familiar with your projects and priorities. You can reach [Successor’s Name] at [email] or [phone].
Before I leave, I’d be happy to set up a short call so the three of us can talk through any open items. Please let me know what times work for you.
Thank you again for a great working relationship. I wish you and your team continued success.
Best regards,
[Your Name]
2. The Long-Term Client Relationship
For clients you’ve worked with for years, a little more warmth is appropriate. Keep the focus on them.
Subject: A personal note and a new point of contact
Hi [Client Name],
After [number] years at [Company], I’ve decided to take on a new opportunity, and my last day will be [date].
Working with you has been one of the highlights of my time here. I still think about [specific project or moment], and how well our teams worked together to make it happen. Thank you for your trust, your patience, and for making the work genuinely enjoyable.
I’ve spent the past few weeks briefing [Successor’s Name] on your account, including your history, your goals for the coming year, and the details that matter most to you. [He/She/They] brings [relevant strength or experience], and I’m confident you’ll be in excellent hands.
[Successor’s Name] will reach out this week to introduce [himself/herself/themselves], and I’d love to join that first call to make sure the transition is smooth.
With sincere thanks,
[Your Name]
3. The Joint Introduction Email
Many companies prefer this approach: you and your successor send the message together, or you send it with your successor copied. It shows teamwork and reassures the client immediately.
Subject: Thank you, and an introduction to [Successor’s Name]
Hi [Client Name],
I’m writing to share some news. I’ll be leaving [Company] on [date], and I’m pleased to introduce [Successor’s Name], who I’ve copied here and who will be taking over your account.
[Successor’s Name] and I have been working together over the past few weeks to make sure nothing is missed. [He/She/They] has reviewed your current projects, upcoming deadlines, and your preferences, and is looking forward to working with you.
We’d love to schedule a quick call before my last day so you can meet properly and ask any questions. Would [day/time options] work for you?
It’s been a pleasure working with you, and thank you for everything.
Best,
[Your Name]
4. When the Company Hasn’t Named a Replacement Yet
Sometimes you have to leave before your successor is confirmed. Be honest, and keep it reassuring.
Subject: Update on your account at [Company]
Hi [Client Name],
I wanted to let you know that my last day at [Company] will be [date]. It’s been a pleasure working with you.
Your account will continue to be fully supported. Until a new account manager is confirmed, [Manager’s Name], our [title], will be your point of contact, and you can reach [him/her/them] at [email]. [He/She/They] is up to date on your current projects and will make sure everything continues smoothly.
Thank you again for a wonderful working relationship. I wish you all the best.
Kind regards,
[Your Name]
5. A Short Version for Smaller or Occasional Clients
Not every client needs a long message. For people you worked with occasionally, keep it brief.
Subject: New contact for your account at [Company]
Hi [Client Name],
Just a quick note to let you know I’ll be leaving [Company] on [date]. Going forward, [Successor’s Name] will be your contact, and you can reach [him/her/them] at [email].
Thank you for working with me, and all the best.
[Your Name]
6. When You’re Joining a Competitor
This situation calls for the most caution. Keep the message minimal, don’t mention your new employer, and don’t suggest any future contact. Many companies will want to send this message themselves, so check first.
Subject: Introducing your new contact at [Company]
Hi [Client Name],
I wanted to let you know that I’ll be leaving [Company] on [date]. Thank you for the opportunity to work with you. I’ve truly enjoyed it.
[Successor’s Name] will be taking over your account and is fully briefed on your projects. You can reach [him/her/them] at [email] or [phone].
Wishing you and your team every success.
Best regards,
[Your Name]
It may feel stiff, but restraint is the point. A neutral, polished message protects you legally and professionally.
Special Situations
If a client asks where you’re going
Clients often ask, especially ones you’re close to. If your company allows it and you’re not going to a competitor, you can answer simply: “I’m joining [Company] as [role].” If you’re unsure, or you’re under a non-solicitation agreement, a warm deflection works: “I’m starting a new role in a different area, and I’m excited about it. But I’m most focused on making sure your transition to [Successor] goes smoothly.”
If a client wants to follow you
Sometimes a client says, “We’ll go wherever you go.” It’s flattering, but handle it carefully. Don’t encourage it, and don’t discuss future work while you’re still employed. A good response: “That means a lot to me, thank you. [Successor] is excellent, and I’m confident you’ll be in great hands.” If the client contacts you later on their own initiative, check your contract and, if needed, get legal advice before responding.
If you’re starting your own business
This is where many people overstep without realizing it. Even if you’re launching a freelance practice in the same field, you usually can’t use your employer’s time, email, or client list to promote it. Keep your goodbye email focused entirely on the transition, and don’t mention your new venture unless your employer has explicitly agreed.
If you’re a freelancer ending a client relationship
If you run your own business and you’re ending work with a client, the rules are different, because the relationship belongs to you. You can be more personal and flexible, but the same principles apply: give notice, hand over work cleanly, recommend a replacement if you can, and thank them sincerely.
Staying in Touch the Right Way
Wanting to stay connected with clients you’ve enjoyed working with is natural. The key is doing it in a way that doesn’t look like solicitation.
Connect on LinkedIn after you’ve left, if your contract allows it. A LinkedIn connection is generally seen as networking, not soliciting, but check your agreement first, since some are strict.
Keep it social, not commercial. Congratulating a former client on a promotion is fine. Pitching them services from your new company is a different matter, and may be restricted for a period of time under your contract.
Let the client initiate business conversations. If a former client reaches out to you about working together, that’s a different situation from you contacting them. Even then, review any restrictions you agreed to.
A Quick Checklist Before You Hit Send
Before sending your goodbye email to any client, run through these questions:
- Has my manager approved the message and the timing?
- Have I checked my contract for non-solicitation or confidentiality clauses?
- Is my successor named, with contact details?
- Have I reassured the client about their ongoing work?
- Did I avoid inviting the client to contact me or follow me?
- Did I leave out negative comments about the company or my reasons for leaving?
- Am I sending it from my work email, not a personal account?
- Is there time for the client to reply and meet my successor before I leave?
If you can answer yes to all of these, you’re ready.
Quick Answers
Should I send a goodbye email to clients when I leave my job?
Usually, yes, but only with your manager’s approval. Some companies prefer to announce departures themselves, so always ask first.
When should I tell clients I’m leaving?
Ideally one to two weeks before your last day, after your successor has been confirmed. That leaves time for a handover call.
Can I tell clients where I’m going next?
Only if your employer is comfortable with it and your contract doesn’t restrict it. If you’re joining a competitor, it’s safest not to mention it.
Can I give clients my personal contact details?
Be careful. Sharing personal contact details can look like an invitation to follow you, which may breach a non-solicitation agreement. Check with your manager and your contract first. A LinkedIn connection after you’ve left is usually a safer option.
What if a client is upset that I’m leaving?
Acknowledge their feelings, thank them for their loyalty, and focus on the transition. Offer a joint call with your successor so they can build confidence before you go.
Should I call clients instead of emailing?
For important or long-term clients, a call is a thoughtful first step, with your manager’s approval. Follow it with an email that confirms the details and introduces your successor in writing.
A goodbye email to clients isn’t really a goodbye. It’s a handover. The best ones say thank you sincerely, introduce the next person with confidence, and quietly make it clear the client is in good hands.
Do that, and you leave behind something more valuable than a nice message: a smooth transition, a client who still trusts the company, and a reputation as someone who does things the right way, right up to the last day.
