Knowing how to write an apology email to angry customers, co-workers, supervisors or business partners is a valuable skill that everyone should possess. In this article, we explain everything you need to know about writing a professional apology email.

Why are apology emails important?

There are clear benefits to a successful apology email. The right kind of sorry email can calm down angry customers, save strained business relationships and restore harmony among co-workers. Sincere apologies show that you take problems, mistakes and misunderstandings seriously and are making an active effort to improve the situation at hand. But different situations will require different approaches. You’ll want to use a different tone and include different content for customers than for a business partner or supervisor.

Below we’ll look at different situations that warrant an apology email and give you tips on how to apologize professionally in an email. We’ll also tell you what should be in an email and include apology email examples and templates.

When and how should you write an apology email?

Once you’ve decided to write an apology email the next question is, what should that email contain? No matter how much experience you have with professional communication, apology emails don’t seem to get any easier.

Below are some tips to help you draft a successful apology email:

How should you apologize?

The most important aspect of an apology is the “how”. The way you express yourself will determine whether the other person believes your apology and can understand your point of view. The biggest elements of a successful apology are honesty, responsibility and transparency. If you made a mistake, you should take ownership of it and apologize sincerely. That will show that you’re professional, earn you respect from the other person and make clear that you’re actively working towards a solution.

Some important things to pay attention to are:

  1. You should never use phrases like “I’m sorry, but…”. If you’re apology reads like an excuse, you might even make the situation worse. Focus on clearly expressing that you’re sorry and showing that you understand the other person’s anger.
  2. Suggest a way to solve the problem and make up for your mistake.
  3. Try to use first-person formulations like “I apologize” rather than impersonal forms like “We apologize”. However, the choice between “I” and “we” will depend on the context. In customer service, it’s more common to use “we” in apology emails.

Which situations call for an apology?

There’s a wide variety of situations that might call for an apology email. That makes it all the more important to develop a sense for when an apology is not only appropriate but absolutely necessary. Below we give you an overview of some business situations that warrant an apology.

Professional or technical mistakes

There are a number of mistakes you can make in the course of doing business that would warrant an apology:

  • Missing a deadline or appointment
  • Sending documents or media late
  • Sending incomplete materials
  • Not answering a message
  • Sending the wrong email attachment or sending an email to the wrong person
  • Accidentally sending confidential information
  • Mixing up appointments
  • Putting the wrong email addresses in CC or BCC

Typos and other careless mistakes

Careless mistakes like typos can often be the most frustrating, because they’re so easy to avoid. If it’s too late to, for example, recall your Outlook email or correct your mistake, show the person in question that you’re professional and conscientious by sending them an apology email. However, make sure to keep things in proportion. If you call someone by the wrong name, you should definitely apologize but not write an essay-length email about it. “Short but sincere” is the name of the game.

Some examples of careless mistakes that you should send a short and sincere apology email for:

  • Using the wrong name
  • Sending an email to the wrong person
  • Writing the wrong job position or job title
  • Using the wrong business name
  • Misgendering

Technical errors

Technical errors are some of the most common mistakes and apologizing for them should be standard. These errors can include:

  • Software or system errors
  • Errors with email lists
  • System failures or slow features
  • Emails that weren’t sent, were mistakenly sent or were sent multiple times
  • Spam that was sent from malware-infected accounts
  • Automatic confirmations or out-of-office emails that didn’t get sent

Apologies when you’re not to blame

Not every situation warrants a direct apology. In some cases, you should try to write an apology without apologizing. That’s especially true if it becomes clear that a “problem customer” is merely trying to get freebies, is blaming you for their mistakes or doesn’t understand certain conditions of the sale.

Your top priority should still be to act friendly and professional. Use formulations like “We’re sorry to hear you were dissatisfied” to help the customer feel understood and acknowledged without explicitly taking blame. You might also be able to use the chance to point out any misunderstandings without coming across as pedantic.

Apologizing for misunderstandings

When it comes to misunderstandings, the most important thing is to clear them up. If you’ve expressed yourself in a misleading way, address it directly and apologize. You should also assure the other person that you’ll be clearer in the future.

Apologizing when you’re both at fault

If both you and the other person made mistakes, fostered misunderstandings or got irritated, you shouldn’t wait for them to make the first move. Use formulations like the following in your apology email:

I’m sorry that we misunderstood each other. In hindsight, we could have avoided those mistakes. That makes it all the more important that we find a solution that’s satisfactory for both of us, so that we can continue working well together.

What should be included in every apology email?

No matter what you’re apologizing for, there are certain things that are true of every professional apology email.

  • Keep it short: Write a sincere apology without any ifs, ands or buts.
  • Don’t make excuses: You should never find yourself writing “I’m sorry, but…”. Avoid making excuses and giving far-fetched explanations. The simplest way to smooth things over is to admit your mistakes.
  • Take responsibility: Don’t stop at an apology. You should also take responsibility for your mistakes. Put yourself in the other person’s shoes and emphasize that you understand the inconvenience your mistake caused. Look for a solution.
  • Propose solutions: Suggest a specific solution in the form of a replacement, compensation or something similar. In addition, communicate the next steps transparently and propose a timeline. That will make it clear that you’re actively working on a solution.
  • Learn from your mistakes: Show that you want to learn from your mistakes and demonstrate how you’re doing that. Assure the other person that you won’t make the same mistake again.
  • Acknowledge the gravity of the situation: If you’ve made a really big mistake, you should also ask for forgiveness to show that you’re serious. This won’t be appropriate in every situation so use your best judgement to make sure you don’t overdo the apology.
  • Don’t take it personally: Especially when it comes to angry customers or business partners, it’s important not to take complaints personally. Defensive replies are a no go.
  • Accept feedback and suggestions for improvement: Show that you’re interested in feedback and suggestions for improvement, both in the current situation and in the future.
  • Good form: In the spirit of email etiquette, make sure you use the right sign off and have a good email signature.

3 examples for professional apology emails to customers

Apology emails to customers can take a wide variety of forms depending on the customer’s complaint. Below we’ll show you three apology email examples for different situations.

Apology email for large groups of customers

If you’ve accidentally sent out an email to a large group of customers using your newsletter list or customer service platform, you’ll want to react as quickly as possible. That’s also true if you’ve been targeted by malware and accidentally sent spam to customers. When it comes to large groups, a standardized, professional email will be most appropriate. The faster and more transparent your response is, the better for your company’s image.

Example: An email announcing sales that are no longer going on was accidentally sent to customers.


It looks like our last email announcing the spring sale was out of date. We’re sorry about that! But don’t worry, you won’t leave empty handed. We’re offering 50% off all marked down items. Simply enter the code SALE with your next purchase.

It’s important that you explain the problem in your own words, don’t hesitate to apologize and offer a solution. By offering customers a discount, you turn the problem into an opportunity for a better brand image.


Based on your company’s style, your apology email can be more casual or more formal. If you take a casual tone, integrate Outlook emojis to keep the message light and fun.

Personalized apology emails to individual customers

A mass email probably won’t have any big consequences for a user’s experience. But system errors are another story.

Example: A company that offers users integrated payment gateways for websites and online store experienced an outage. They want to apologize to their customers personally and professionally.


Dear [name of customer],

On behalf of the team at [company name], I want to sincerely apologize for the recent problems with our integrated payment gateway. We understand how crucial the payment system is for your business and can completely understand your frustration. We’re already in contact with the gateway provider and can promise a solution within the next twelve hours.

Until the problem with the gateway is solved, we can offer you one of our alternative gateway solutions. Since setting up a new gateway can involve extra work, we’re here to help integrate it into your site, so that your business can go on without any further interruptions.

We’d also like to assure you that we’re making efforts to prevent similar problems in the future.

Thank you!
