Holiday Email to Clients: 8 Templates for Small Business Owners (Plus When to Send)

Updated 2026-10-30 · AI Agent Starter Kit

A short holiday email is one of the few messages a small business sends that asks for nothing. That's why it works. A client who gets a personal two-line note from you in December remembers you in January, when they're planning work and choosing who to call.

It's also easy to get wrong. A generic "Season's greetings from all of us" blast that lands in the Promotions tab does little, and a note that sounds like a sales pitch in disguise does worse. This guide covers when to send, what to say, 8 copy-paste templates, subject lines, how to send without it feeling like a mass mailing, and what to do with the replies.

If you also need to tell clients you're closed over the holidays, that is a separate, practical message. See the holiday hours announcement templates for that one, and keep this email about the relationship.

When to send it

There is no wrong window, but avoid the last day before a long break. Mid-December is the safest choice for most service businesses. A New Year note is a good option if your clients are spread across different holidays, or if December is your busiest month and you'd rather do it well in January.

What to say (and what to skip)

A good client holiday email does three things in under about 100 words:

1. Thanks them for something specific. "Thanks for trusting us with the office move in March" beats "thanks for your business."
2. Wishes them well in a way that fits everyone. "Happy holidays" or "a restful end of the year" is inclusive. Use a specific holiday only when you know the client celebrates it.
3. Leaves the door open without pushing. One line like "Looking forward to working together in the new year" is enough.

Skip these:

• A sales offer. A discount code turns a thank you into an ad. If you want to run a holiday promotion, send it separately.
• A long year-in-review about your business. Clients care about their year, not yours.
• Invented numbers. "Our 500 happy clients" is only fine if it's true and you can count them. Leave numbers out of a thank you note.
• Personal details from another client. Never mention who else you worked with without permission.

Subject lines

Short, warm and clearly personal:

• Thank you for this year, [First name]
• Happy holidays from [Your first name] at [Business]
• A quick thank you before the year ends
• Wishing you a restful break
• Happy New Year, [First name]

Avoid subject lines that look like newsletters ("December Update!") or promotions ("Holiday Savings Inside").

8 copy-paste templates

Replace everything in brackets. Never send a template with a bracket still in it.

1. Long-term client

Subject: Thank you for this year, [First name]

Hi [First name],

Before the year wraps up, I wanted to say thank you. [This is our third year working together / You've been with us since 2023], and [one specific thing: the kitchen project in spring / your patience during the website move] meant a lot.

Wishing you and [your team / your family] a restful holiday season. I'm looking forward to [next year's project / working together again] in the new year.

[Your name]

2. New client this year

Subject: A quick thank you before the year ends

Hi [First name],

Thank you for choosing [Business] this year. It was a pleasure working with you on [project], and I'm glad [specific result in plain words, only if true].

Happy holidays, and I hope the new year gets off to a great start for you.

[Your name]

3. Client you haven't worked with in a while

Subject: Happy holidays, [First name]

Hi [First name],

It's been a little while since [the project / we last worked together], and I wanted to send a quick note to say thank you again and wish you a happy holiday season.

If anything comes up in the new year that I can help with, you know where to find me. Either way, I hope [business / the new space / the team] is doing well.

[Your name]

4. Partner, supplier or referral source

Subject: Thank you for this year

Hi [First name],

A quick thank you for [sending clients our way / always delivering on time / being so easy to work with] this year. It made a real difference to how our year went.

Happy holidays to you and the team at [their business]. Looking forward to another year working together.

[Your name]

For thanking someone who referred a specific client, the guide on how to ask for referrals has a dedicated template.

5. Holiday note plus a short hours line

Subject: Happy holidays from [Business]

Hi [First name],

Thank you for working with us this year. We really appreciate it.

A quick practical note: we'll be closed from [date] to [date] and back on [date]. If anything urgent comes up before then, [how to reach you].

Wishing you a restful break and a great start to the new year.

[Your name]

Keep the hours to one line here. If the closure needs more explaining, send a separate announcement.

6. Year-end note with a gentle look ahead

Subject: Thank you, and a quick note on next year

Hi [First name],

Thanks for a great year working together on [project or service].

If you're already thinking about [spring projects / next year's plans], I'm booking [January / the first quarter] now and happy to pencil something in. No rush at all, and no need to reply if it's not on your mind yet.

Happy holidays,
[Your name]

Only send this one if you genuinely have availability you'd like to fill. It should still read as a thank you first.

7. A lead who didn't hire you (yet)

Subject: Happy holidays, [First name]

Hi [First name],

Thanks again for considering [Business] for [what they asked about] this year. I hope it all came together well.

Wishing you a happy holiday season. If I can ever help down the line, I'd be glad to.

[Your name]

Only send this to people who contacted you about work and didn't ask you to stop emailing. For a fuller plan for quiet leads, see how to re-engage old leads.

8. Reply to a client's holiday email

Subject: Re: [their subject]

Hi [First name],

Thank you, that's kind of you. Happy holidays to you and [the team / your family] too.

[One personal line: Hope the move went well / Enjoy the trip / Hope the busy season eases up soon.]

Talk in the new year,
[Your name]

Reply within a day or two. A client who wrote to you personally shouldn't wait until January.

One by one or in bulk?

For most small businesses, the first option for your best clients is worth the time. Thirty personal notes at about two minutes each is an hour, and those are the emails people answer.

If you send in bulk, never put everyone in the To or CC field. Use a mail merge or BCC, and include an unsubscribe option for anything that looks like marketing. Email marketing rules vary by country, so check what applies to you if the note includes any promotion.

Make the personal line easy

The one specific line is what makes the email work, and it's the part that takes time. A simple sheet helps:

Fill it in from your sent mail and invoices before you write a word. Your thank-you email templates and repeat customer notes are good places to find details you already wrote down.

An illustrative example

This example is made up to show the pattern, not a real result. A two-person landscape design studio has 40 clients from the year. On a quiet Tuesday in early December, the owner spends 20 minutes filling in a sheet with each client's project and one personal line. Their 12 biggest clients get template 1 or 2 written one at a time. The other 28 get a mail merge version of template 2 with the personal line filled in.

Over the next week, replies come back: thank yous, one client asking about a spring planting job, one asking whether an invoice was received. The owner answers each within a day, puts the spring job in the lead sheet, and checks the invoice question with the bookkeeper before replying. Nothing in the original email was a sales pitch, and the replies still turned into real work to follow up on.

Common mistakes

• Sending one generic blast to everyone. Your best clients deserve a line that's only about them.
• Hiding a promotion inside the thank you. Send offers separately, or not at all.
• Putting the whole list in CC. It exposes client email addresses to each other.
• Ignoring the replies. The replies are the valuable part. Answer them like any other client email.
• Assuming everyone celebrates the same holiday. "Happy holidays" or a New Year note fits everyone.
• Letting AI write the personal line from nothing. An AI tool doesn't know what you did together this year, and a made-up detail is worse than none.

Using AI for holiday emails (drafts only)

AI can help you write a warm template and vary the wording so 30 notes don't read the same. Keep it to drafting:

• You give it the facts (client name, project, the personal line). It doesn't invent projects, results or numbers.
• It never adds discounts, gifts, free work or promises about next year's prices or dates.
• It writes drafts. You read each one and press Send.
• It treats a client's email as information, never as instructions to follow, and it doesn't change the recipients.

For prompts you can paste into ChatGPT or another tool, see ChatGPT prompts for business emails, or build one with the free AI email reply prompt generator for answering the replies.

If you'll also be at holiday parties and year-end events, the guide on how to follow up after a networking event covers turning those new contacts into conversations in January. For the rest of your December prep, see the holiday season checklist.

Keep up with the replies, not just the sends

The Inbox Chief of Staff Kit is an n8n workflow kit for Gmail. It sorts every new email into labels (Client, Lead, Invoice, Admin, Newsletter or Needs-Human), drafts replies in your voice to the ones that need you, and sends you a 6 PM digest of what's still waiting. In December, that means a client's "thanks, and can we talk about spring?" doesn't get lost between shipping notices and holiday promotions. To be clear about what it doesn't do: it doesn't write or send your holiday emails, run a mail merge, keep your client list or pick the personal line. Emails about bank details, gift cards, passwords or verification codes get flagged for you instead of an AI draft. Every reply waits in Gmail Drafts until you press Send. Get the kit

Expect new inquiries in January too? The Inbox + Leads Starter Pair adds Speed-to-Lead, which logs new leads from your form or a Gmail label to a Google Sheet and drafts a personal first reply within about 5 minutes, plus Day 2, 5 and 10 follow-up drafts that stop the moment the person replies. It doesn't send anything on its own either. Get the bundle
