The end of the year arrives and many companies want to acknowledge their clients, suppliers or international partners. The problem is a familiar one: you know what you want to say, but not always how to express it correctly in English without sounding cold, unnatural or too informal. In this article you will learn how to write a year-end email in English suited to a professional context, with practical examples and tips for avoiding common mistakes.

Why the year-end email matters more than it seems

For many companies, this email is the last point of contact of the year. It is not a simple greeting: it reinforces the relationship, leaves a final impression and sets the scene for the year ahead. A poorly written message can come across as distant, rushed or careless.

In B2B settings, particularly international ones, language matters. The tone should be professional, warm and consistent with the existing relationship. Writing to a strategic client is not the same as writing to a recent business contact.

Tone and approach: what your clients expect in English

One of the most common mistakes is translating literally from Spanish. Phrases that work well in Spanish can sound excessive or unnatural in English. In year-end emails, the approach is usually more restrained and direct.

In general, readers appreciate:

• Sincere thanks, without exaggeration.
• Clear, short messages.
• A positive, forward-looking close.

The aim is not to impress with complex vocabulary, but to communicate clearly and professionally.

A recommended structure for a year-end email in English

Although every company adapts the message to its own style, a clear structure helps you stay on track:

A brief, polite opening
A standard greeting works better than creative formulas. “Dear [Name]” or “Dear [Company/Team]” is usually enough.

The main message
Here you thank the reader for their collaboration over the year and acknowledge the working relationship. Being specific matters: mentioning the work you have done together adds authenticity.

A look ahead to next year
A positive wish or a reference to the future reinforces continuity and commitment.

A professional close
A well-chosen sign-off keeps the corporate tone without sounding distant.

Practical examples of year-end emails in English

Below are some common templates you can adapt to your own context.

Formal email for clients or partners

Dear [Name],

As the year comes to an end, we would like to thank you for the trust and collaboration throughout this year.

We truly appreciate working with you and look forward to continuing our cooperation in the coming year.

Wishing you a successful and prosperous New Year.

Kind regards,
[Name / Company]

This type of message works well when the relationship is formal or institutional.

Professional email with a warmer tone

Dear [Name],

Thank you for working with us over the past year. It has been a pleasure collaborating with you and your team.

We look forward to new projects and opportunities together in the year ahead.

Best wishes for the New Year,
[Name]

This suits established relationships where there is a degree of professional closeness.

Common mistakes worth avoiding

At ALOS we often see emails with mistakes that are not serious but do make them look less professional. Some of the most common are:

• Using expressions that are too informal (“Happy holidays!” with no context).
• Translating Spanish set phrases word for word.
• Messages that are too long or loaded with adjectives.
• Basic grammar mistakes that create a poor impression.

Avoiding these slips does not require advanced English, just an understanding of the right register and a careful read-through.

Standard template or personalised message?

A common question in companies is whether to send the same email to every contact or to personalise it. The answer depends on the volume and the type of relationship. For large databases, a well-crafted template is enough. For key clients, it is worth adapting a sentence or two.

Even small changes—mentioning the type of collaboration or the main project of the year—make a difference. This approach shows attention and strengthens the business relationship.

The email as a mirror of the company’s level of English

These emails also reveal the real level of corporate English. If every year brings doubts or hesitation when writing them, it is usually a sign of a broader need to improve written communication.

On the ALOS blog you will find more content on how to improve professional English communication in the workplace, with examples you can apply to emails, meetings and presentations. Resources like these help you gain autonomy and consistency in your external communication.

When to ask for professional support

If your company handles frequent communication in English, linguistic support can save time and prevent mistakes. It is not just about translating emails, but about setting clear criteria on style and tone for the whole organisation.
