Every December your customers' inboxes turn into a car park.
Constant Contact's 2025 holiday report surveyed more than 1,800 small business owners across Australia, New Zealand, the US and the UK. It found 60% planned to increase how often they send marketing communications over the holiday period. So most of the businesses your customers already buy from are about to contact them more often, at the same time, with roughly the same message.
Most of those emails will say some version of "Sale! Don't miss out!"
Most of them will be ignored.
You will not win by sending more than everyone else. Send five emails in the right order, each doing one job, before the noise peaks: a reactivation email, a proof email, an offer email, a deadline email and a thank you email. That sequence suits shops, trades, clinics and consultants alike. Below is how to write each one and when to send it.
Why a sequence beats a blast
A single promotional email asks a cold reader to go from not thinking about you to buying in one step. That is a big ask in any month, and far bigger in a crowded December inbox.
A sequence breaks the decision into smaller steps. Remember us. Believe us. Want this. Act now. Thanks for trusting us. Each email sets up the next.
There is a practical reason too. Mailbox providers judge you on how people respond. Yahoo's sender guidelines put it bluntly: sending email to people who are not reading it will harm your delivery metrics and reputation. Blast a cold list and you damage your standing just before the offer email goes out. A sequence that starts gently and wakes the list up first protects the delivery of the email that matters most.
One email asks for the sale. Five emails earn it.
Email one: the reactivation
Job: get opened by people who stopped opening.
Send it in October or early November, before promotions start. Everyone on your list who has not opened or bought in months needs a reason to notice you again. A discount will not do it, because you have not given them a reason to care yet.
Write it like a person. A short, plain note from the owner that says what has changed since they last heard from you, gives them one useful thing, and asks a simple question they can reply to.
Then clean the list. Anyone who ignores a reactivation email should be suppressed before your big send. Gmail's own advice to senders is to consider unsubscribing recipients who don't open or read your messages.
Here is the sort of thing that works. Subject line: "Quick one from Sarah at the shop." Body: three short paragraphs. We moved to a bigger workshop this year. Here is the one thing customers keep asking us about, answered. Are you still using the thing you bought from us, and how is it going? That last question earns its place. Every reply proves someone is reading, and it hands you real customer language to use later in the sequence.
Email two: the proof
Job: make the offer believable before you make it.
This email sells nothing. It shows a result: the problem a customer had, what you did, and what changed. A before and after photo does it. So does a short video of the product in use.
Most businesses skip this and go straight to the offer, which is why their offers read as noise. When a reader saw proof a few days earlier, the offer arrives with credibility already attached.
Pick the story that answers the biggest doubt your buyers have. If people worry about price, show the value someone got. If they worry about hassle, show how easy it was. Proof aimed at the real objection will outsell proof chosen because it was the prettiest.
The story is already sitting in your reviews or your inbox. Look for the customer who said "I wish I had done this sooner" or "I was nervous about" something. Ask their permission, get a photo if you can, and tell it in their words. Readers trust a customer who sounds like a customer.
Email three: the offer
Job: make one clear proposition.
One offer. One button. What they get, what it costs, why now, and what happens if it goes wrong. If you have a guarantee, put it near the top, well away from the footer.
The offer does not have to be a discount. A bonus, a bundle, priority booking before the holiday rush, or this year's price locked in for next year can all work, and none of them train your customers to wait for a sale.
Give a real reason for the offer. "We have limited installation slots left before Christmas" is a reason. "Holiday sale" is wallpaper.
A simple structure for the body:
- The headline. What they get, in one sentence.
- Who it is for. The specific person or problem this suits.
- What is included. Three or four short bullet points. Skip the full feature list.
- The risk reversal. Your guarantee or returns policy, in plain language.
- The reason and the date. Why this offer exists and when it ends.
- One button. A clear action like "Book your slot" or "Get the bundle".
Email four: the deadline
Job: convert the people who meant to.
Plenty of people will open your offer, like it, and do nothing. They are busy, and a deadline is what moves busy people.
The deadline email is short. What they get, when it ends, the button. Send it on the final day, and if you have the nerve, send a brief reminder a few hours before close to anyone who has not bought.
Keep the subject line honest and plain. "Ends tonight" works because it is true and the reader can use it.
The one rule is that the deadline must be real. If the offer quietly comes back next week, your list learns your deadlines are fiction, and every future deadline stops working.
Email five: the thank you
Job: turn a December buyer into a January customer.
Almost nobody sends this one, so yours stands out. Thank everyone who bought, and write a separate note to everyone who simply read along all year.
No offer. Tell buyers what happens next, how to get the most from what they bought, and who to contact if something is not right. Ask for a reply or a review while the goodwill is warm.
Buyers who feel looked after in December are the ones who open your email in February. Do this well and next year's reactivation email has far fewer people to chase.
The setup checklist
- Segment before you send. Recent buyers, lapsed buyers and people who have never bought should not get identical copy. At minimum, exclude anyone who already bought from the deadline email.
- Space them out. Reactivation first, proof a week or so later, then offer, deadline and thank you inside the promotion window.
- Write subject lines like a friend would. Specific and plain beats capital letters and exclamation marks in a crowded inbox.
- One call to action per email. Every extra link is another reason to do nothing.
- Check the basics. Sending domain authenticated, unsubscribe link working, mobile layout tested. No copy can save an email that lands in spam.
- Judge by revenue. Track sales per email sent. Opens are a shaky number, because Apple's Mail Privacy Protection downloads remote content in the background whether or not the person reads the email, and that can register as an open.
On authentication, if you have never looked at it, ask whoever set up your email platform whether SPF, DKIM and DMARC are configured for your sending domain. These records prove to inbox providers that you are who you say you are. Gmail asks every sender for SPF or DKIM, and wants all three from anyone sending more than 5,000 messages a day. Most email platforms walk you through it, and you only do it once.
A worked example of the timing
Here is a hypothetical sequence, so you can see the spacing in practice.
Say you run a Perth bike shop with a list of 3,500 people, most of whom bought once and went quiet. Your offer for the season is a free service with any new bike bought before Christmas, which protects margin better than a price cut.
- Late October. Reactivation. A plain note from the owner about the new workshop hours and a tip on getting a bike ready for summer, ending with "What are you riding these days?" A few dozen people reply.
- Early November. Proof. The story of a customer who came in nervous about buying their first road bike and is now riding every weekend, in their words, with their photo.
- Mid November. Offer. Free service with any new bike before Christmas, what the service includes, the no questions returns policy, and a single "Book a test ride" button.
- Offer end date. Deadline. "Free service offer ends tonight" to everyone who has not bought.
- Mid December. Thank you. A note to buyers explaining the first free service and how to book it, and a separate thanks to the wider list with a summer riding tip.
Between the reactivation and the big send, the shop suppresses addresses that never engaged. The offer lands in inboxes that recently opened and replied, and the deadline goes only to people who have not yet bought.
Start this week
Do not wait until the last week of November to write one panicked email at midnight.
Open a document tonight and write five headings. Reactivation. Proof. Offer. Deadline. Thank you. Draft the first one before you go to bed, and send it while your competitors are still designing their sale banner.
By the time the inbox turns into a car park, your customers will already know your name.
This sequence is one part of a bigger plan. If you want the rest of the build, list growth, audience warming and the full offer calendar, read why Q4 is won in the weeks before Black Friday. And if you have been treating email as an afterthought, read the case for email as your highest-ROI channel. When you would rather have the sequence written, built and tracked for you, our digital marketing team at LIQID NOISE does that.
Frequently asked questions
How many emails should I send during the holiday season?
Fewer than you think, as long as each one has a job. Five well spaced emails are enough: reactivation, proof, offer, deadline and thank you. A daily blast of near identical promotions only adds to the noise in a crowded December inbox.
What should a reactivation email say?
Keep it short and personal, ideally from the owner. Share what has changed, give one useful tip, and ask a simple question people can reply to. Do not lead with a discount. Its job is to get quiet subscribers opening again before the promotional season, so you can clean out the ones who never respond.
Why are my promotional emails going to spam in December?
Often because a cold, unengaged list is suddenly emailed heavily, or because your sending domain is not properly authenticated. Check SPF, DKIM and DMARC with your email platform, remove addresses that never open, and warm the list up with a useful reactivation email before your main offer goes out.
Should I measure email success by open rate?
No. Opens are unreliable, because some mail apps load an email in the background even when nobody reads it. Measure revenue per email sent and the sales each email in the sequence produced. That tells you which messages move buyers and where to focus next year.
