Christmas is the biggest few weeks of the year for a lot of email programs, and the most crowded. There’s real opportunity, but inboxes are full, mailbox providers are busy, and small mistakes get magnified.

An assessment of last year’s industry trends and an acute awareness of how your users are interacting with your content should be high on your list. But there’s plenty more you can do to make your Christmas email marketing campaigns a roaring success.

Use these 10 tips to boost your Christmas email marketing campaigns and uncover any potential weaknesses in your strategy, so you can truly make the most of this holiday season.

Plan Ahead

While there’s no golden rule with respect to exactly when to start planning your Christmas email marketing campaigns, earlier is usually better. Have your offers planned out. Your template designs ready to go. Your sales copy ready to test. Your automations, including abandoned cart emails, all set up in advance.

If you’re planning to increase your send volume over the holiday period, be careful. Since November 2025, Gmail has been actively deferring and rejecting mail from senders who don’t meet its sender requirements, and a holiday surge is exactly when weak spots show up. Make sure your SPF, DKIM and DMARC are in place, one-click unsubscribe works, and your spam complaint rate is comfortably under Gmail and Yahoo’s 0.3% limit before the busy season starts. Increased sending rates over a short time period risks triggering spam filters, and damaging your sender reputation. This can impact email deliverability. To avoid this avoid sudden changes in sending practices. By planning ahead, you can calculate precisely how to ramp up your sending rates, as well as your inbox placement and read rates, to avoid any nasty surprises.

Spruce Up your Subscriber List

While it may be tempting to send your Christmas email campaigns to everyone on your list, casting such a wide net can have unintended consequences. Inactive subscribers, low engagement rates, and spam traps can severely hamper your sender reputation.

To combat this risk, remove inactive subscribers from your list. You could even use reputable email validation service to clean your list further.

As always, resist the urge to purchase subscriber files that may contain hidden nasties that’ll get in into a world of trouble. A smaller clean list is always preferable to a larger dirty list.

Reconnect With Disengaged Subscribers

A clean list may be a fresh start, but you don’t want to completely lose the chance to reconnect with your inactive subscribers. So before you get too heavy handed with your list pruning, consider first creating a win-back (or re-engagement) campaign to remind disengaged users the value of your brand.

Do this well before the holidays, not in December. Sending to a big inactive segment at the busiest time of year is a good way to pick up spam complaints and bounces right when you can least afford them.

As a couple of examples, you could send out your most popular content to these subscribers to try and pique their interest. Maybe send a unique, time limited discount code, or an exclusive offer just for them.

Keep an Eye on Your Stats

Before you click the send button you’ll first want to know that your emails are landing in the subscriber inbox. This is particularly true in busy times of the year when an increase in email volumes can put a strain on deliverability rates.

If you’re sending more promotional campaigns than usual, watch for signs of trouble. More of your mail may land in Gmail’s Promotions tab, which is still the inbox and not a disaster, but rising complaints or bounces can push it into spam.

It’s important to monitor your performance by keeping an eye on your stats so you can be sure that all your hard work is paying off. There are free email marketing tools that can help with this.

Watch your spam complaint rate, bounces and clicks after every send. Otherwise, a problem could go unnoticed, thereby lowering the ROI of your Christmas email marketing campaigns.

Use Calendar Triggered Events

Schedule some carefully crafted emails both in the run-up to Christmas, and post-Christmas to make your overall campaign as successful as possible.

As a few ideas: send out a campaign a few weeks before Christmas letting subscribers know about your most popular products. Send another listing your best Christmas deals. And another reminding people that “today is the last chance to order to guarantee delivery before Christmas!”.

After Christmas, send an automated message letting people know about your best post-Christmas offers, etc. Be as creative as you can with these messages.

Listen to Your Users

Pay attention to what your website visitors and subscribers are telling you through their behavior, so you send content they actually want. Ask yourself what improvements can be made to your content to better align with what users want.

Try to focus on performance-based user feedback rather than making generalizations about your list. Look at metrics such as which email clients subscribers are using, which devices they are viewing emails on, and what times of day have the highest engagement rates. Keep an eye on the kind of links your subscribers click, their average purchase price, which products are bought alongside each other, and any other information you have access to.

Use this data to create better and more personal content which will have a positive effect on your conversion rate.

Test, Test, Test

It’s not always possible to know how your users will react to your content ahead of time. Instead of taking a gamble on your whole list, why not try segmenting your list to test key elements of your campaign?

Subject lines, template design and calls to action are all easy to test. Judge the results on clicks and sales rather than opens, since Apple Mail Privacy Protection makes a lot of opens automatic.

Stand Out

Competition is fierce at Christmas, and you only have a moment to catch the reader’s attention. This, mixed with the fact that many businesses rely on Christmas for most of their yearly sales, means you need to think big.

Powerful subject lines, personalization, and emojis are all things you can use to stand out from the crowd. Pull up the results from your A/B split tests and review your user engagement stats to find out which elements are most likely achieve the highest ROI. Design fresh email templates specifically for your Christmas campaigns. Include a countdown GIF to create a sense of urgency. Send automated follow-up emails to remind people about offers they showed interest in.

We’d also recommend going one step further, segmenting your list based on user data to create targeted campaigns for each group.

Monitor Your Sender Reputation

We’ve mentioned this in passing, but it’s worth reiterating. A deliverability problem in December can cost you a big share of your year’s results, so it pays to be watching. There are good free ways to monitor your reputation and spot blocklist problems early.

Google Postmaster Tools is an excellent, free way to access data and diagnostics that impact your sender reputation in Gmail. Used in conjunction with reputable domain blacklist and email spam check tools it can provide delivery error reports, spam reports, and feedback loops to help you stay on the right track. We’ve written a full overview of Google Postmaster Tools, and also listed free tools that can help you keep an eye on your sender reputation.

Keep to Email Best Practices

Sometimes it’s not enough simply to stay off the blacklists. You’ll also want to prove yourself as a safe, responsible sender by maintaining best practices and being an all round responsible email marketer. Safe senders enjoy a higher percentage of emails delivered to the inbox and less risk of being placed in the spam folder.
