Black Friday, Cyber Monday (BFCM), and the holiday season can be some of the busiest times of the year for email marketers. Consumers expect deals, inboxes are flooded with offers, and every brand is competing for attention. The difference between campaigns that succeed and those that get ignored often comes down to preparation and execution. 

In our recent Mailjet Email Academy webinar, Plan, send, and succeed this BFCM and holiday season, in-house experts Natalie Lynch (Principal Product Manager) and Julia Murljacic (Senior Email Marketing Manager) walked through the exact steps you need to make sure your campaigns don’t just sail out into the ether – they land, get read, and drive results

Here’s a full breakdown of the key takeaways and step-by-step process outlined in the webinar.

Step #1: Plan early and set yourself up for success 

So, when should we start thinking about our BFCM campaigns? Well, some interesting insights to come out of our report BFCM email marketing: What consumers want in 2025 indicates that over 50% of consumers want to hear from brands at least one month before Black Friday. If you’re waiting until Thanksgiving week, you’re already too late.

And it’s not just about timing. We also saw that email remains the preferred channel for Black Friday and Cyber Monday promotions, with 56.5% of respondents selecting it over the likes of WhatsApp, websites, and social media ads. Planning early ensures your campaigns reach customers where they actually want to hear from you.

Define your goals and KPIs 

Before you start any kind of campaign planning, you need to define your goals. What are they? What does success look like for you? Here are some tips that Julia highlighted in the webinar: 

  • Tie each campaign to a clear goal so you know what to measure. 
  • Be specific: Do you want a 20% revenue lift, 15% higher repeat purchases, or more website traffic? 
  • Don’t just say ā€œincrease engagementā€ – define whether that means. Higher click-throughs, conversions, loyalty sign-ups? 

Identify your stakeholders and resources

OK, so you’ve got an idea of what you want to achieve – now it’s time to think about everything needed to make that happen. Firstly, you’re going to want to lock in your audience and segments. Who does this campaign benefit, and within that group, do you need to segment down further? Then you can start getting more tactical. 

Julia highlighted some further areas you might want to consider  

  • Map out who needs to be involved internally within the organization: design, copy, developers, compliance, sales… (if you’re a one-man band well, that’s you!) 
  • Gather campaign assets early: graphics, product images, promo codes, and landing pages. 
  • Coordinate across channels – align your social ads, SMS, and website banners with your email campaigns for a consistent brand experience. 
  • Map out the timing of your sends. 

Strengthen your deliverability foundations 

Emails that fail to reach your customers and prospects are missed opportunities to connect and engage. That’s why deliverability is often referred to as that ā€œinvisible layerā€ of campaign success. If you skip this, even the best campaigns will fall on deaf ears. So, to combat that, Natalie suggests that you: 

  • Authenticate your sending domain (SPF, DKIM, DMARC) to prove legitimacy to mailbox providers. 
  • Regularly clean your lists and validate contacts – in our Road to the Inbox 2025 research, 39% of senders admitted they rarely or never do list hygiene, even though it’s essential for inbox placement.  
  • Implement a one-click unsubscribe – not just for compliance, but to prevent recipients from marking emails as spam. 

Step #2: Send smart and build momentum 

With inboxes more crowded than Anfield on derby day, you can’t afford to make mistakes. This means how you roll out your sends – who you target, how you test, and how quickly you scale – can make or break the performance of your campaigns.  

So, how do you ensure success?  

Warm up before you go big 

Warming up your list before BFCM helps inbox providers see consistent, positive engagement, so your emails actually land in the inbox instead of spam. If you blast your entire list at once, you risk high bounces, complaints, and a damaged sender reputation right when you need deliverability most. 

  • Begin with your most engaged contacts (e.g., those active in the last 30–90 days). 
  • Gradually expand to larger segments to build positive signals with ISPs. 
  • Avoid sending to your full list cold – it increases the risk of being filtered to spam. 
  • Keep an eye on performance metrics and refine your segments throughout the warm-up phase. 
ā€œI would suggest that all of September could be considered the ā€œwarm-up phaseā€ and perhaps the first two weeks of October, too. So, you’ve got a good two weeks to really build this up.ā€

Segment and personalize 

Generic emails blend into inbox clutter. Segmenting and personalizing your campaign ensures subscribers get offers that feel relevant, which boosts opens, clicks, and conversions. Sending one-size-fits-all blasts, on the other hand, leads to lower engagement and a higher chance of being ignored or marked as spam. Some options you have are to: 

  • Segment by behavior: loyal customers, first-time buyers, inactive subscribers. 
  • Segment by engagement: openers/clickers in the last 90 days vs. dormant contacts. 
  • Use personalization: names, product recommendations, location-based offers. 

This isn’t just theory – our research shows that email campaigns that feel anticipated, personal, and relevant perform best. Consumers are more likely to engage when emails look like they were created for them, not for ā€œjust another name on a list.ā€

Test before launch 

Now, before hitting that send button, it’s important to test and see how your BFCM emails render. This ensures you catch any links, images, and layout issues across devices and inboxes, protecting you from embarrassing mistakes. It also saves revenue and credibility that could be lost if customers see broken or unprofessional emails.  

  • Preview your emails across devices and clients. A design that works in Gmail may break in Outlook. 
  • Ensure your A/B tests are set up correctly. 
  • Run through every link, coupon code, and personalization token to avoid embarrassing errors.

NOW you are able to hit send… 

But remember, timing is everything. You don’t want to send your campaign at 9:00 AM Eastern if you’ve segmented your audience by region and this group live in California. Also, make sure you’re using email automation to help schedule your campaigns. Unless you’re the type of sender that needs their finger on the trigger, this can help save a bunch of time and manual effort. 

Step 3: Measure and optimize for long-term success 

Don’t set and forget! Hitting send does not mark the finish line – it’s the start of a feedback loop. Success around BFCM isn’t about a single campaign but about learning and improving continuously. 

Track the right metrics 

Beyond checking that the campaign was sent correctly, what metrics should you be tracking, and why? Here are some of the most common to keep top of mind: 

  • Engagement: opens, clicks, unsubscribes. Which content resonated most with your audience? 
  • Delivery: bounce rates and spam complaints.  
  • Conversions: revenue, coupon redemptions, and goal completions from email. 

Remember, you’re not just track for the sake of numbers – insights matter. Inboxes are crowded, with consumers receiving dozens of promotional emails a day. Measuring what cuts through will help you refine your future sends

Pro tip: Wait at least 48 hours after the campaign has been sent to start gathering performance data. This gives enough time to all subscribers to access and engage with your campaign.

Keep the party going

So, what’s next? While you might be ready to hang your hat up and pat your back on a job well done – the real goal here is long-term retention. How can we keep these new subscribers and buyers engaged beyond the holiday season campaign? Natalie ran through a few options for you to consider: 

  • Send thank-you emails or follow-ups with related product recommendations. 
  • Provide educational or loyalty-focused content as part of an onboarding or nurture workflow
  • Build post-holiday nurture flows so seasonal buyers become year-round customers.
