Black Friday and Cyber Monday (BFCM) are golden opportunities for online stores to drive sales-but there’s a hidden challenge: BFCM emails from going to spam. With the surge in email volume during these peak shopping days, ensuring your messages land in inboxes is tougher than ever.
In fact, studies show that up to 20% of marketing emails never reach their intended audience due to spam filters. So, what can you do to avoid this problem? Email deliverability best practices like authentication protocols (SPF, DKIM, DMARC) and careful list segmentation are essential.
Combine these strategies with engaging content and strong sender reputation management, and your emails will stand out in crowded inboxes-boosting engagement and, ultimately, sales during the busiest shopping season of the year.

Preparing Your Email Infrastructure
Before launching your BFCM email campaigns, secure your email infrastructure! Think of it as building a strong foundation-without it, your emails risk landing in spam. In this section, we’ll show you how to set up key authentication protocols (SPF, DKIM, DMARC) and the importance of a dedicated sending domain to protect your reputation and boost deliverability.
Implementing Email Authentication Protocols (SPF, DKIM, DMARC)

SPF (Sender Policy Framework) is like a bouncer at the nightclub of your email server. It checks if the sending server is authorized to send emails on your behalf. If it’s not, the email gets blocked.
DKIM (DomainKeys Identified Mail) adds an encrypted signature to your emails, verifying that they haven’t been tampered with during transit. It’s like sealing your emails with a wax stamp to confirm authenticity.
Lastly, DMARC (Domain-based Message Authentication, Reporting & Conformance) works as your email’s personal bodyguard. It ensures that only emails passing SPF and DKIM checks reach your subscribers, and it gives you valuable reports on any suspicious activity.

Setting Up a Dedicated Sending Domain
Using your store’s main domain to send emails can hurt its reputation, especially if any of your BFCM emails are flagged as spam. That’s where a dedicated sending domain comes in. By isolating your email activity from your main website, you can maintain a cleaner, more trustworthy reputation for both your emails and your website.
Think of it like moving your email marketing into its own clean and professional office space-free from the clutter of your everyday website activity.
Setting it up is simple: configure a subdomain like “email.yourstore.com”, update your DNS settings, and point all your email activity to this subdomain. This helps keep your main domain in the clear and increases the likelihood of your emails reaching your customers’ inboxes.
Building and Maintaining a Healthy Email List
A clean, engaged email list is the foundation of any successful email campaign. Regularly cleaning and validating your list ensures that your messages reach real, interested subscribers and avoid spam traps.
By segmenting your audience effectively, you can send more personalized, targeted content that drives engagement, improves deliverability, and boosts conversions.

Segmenting Your Audience Effectively
When it comes to email marketing, one size doesn’t fit all. Segmenting your audience helps you send more personalized, relevant content to the right people at the right time.
- Engagement Levels: Segment subscribers based on their activity. For example, send targeted emails to those who frequently engage with your content, while re-engagement emails can go to those who haven’t opened your messages in a while. This keeps your communication relevant and improves your email deliverability.
- Purchase History: Target customers based on their past purchases. If someone bought a winter jacket last year, they might appreciate a special offer on accessories or new styles. Personalized product recommendations drive more conversions and enhance customer satisfaction.
- Other Criteria: You can also segment by location, interests, or browsing behavior on your website. For example, if someone has shown interest in a particular category, such as electronics, send them offers and promotions specific to that category.
Benefits of Targeted Messaging:
- Higher Engagement: Personalized emails feel more relevant, which leads to higher open and click-through rates.
- Better Deliverability: By targeting the right people, you reduce the chance of your emails being marked as spam.
- Increased Conversions: Tailored content increases the likelihood of recipients taking action, whether that’s making a purchase or clicking through to your site.
Crafting Compliant and Engaging Email Content
To make your BFCM emails stand out, focus on valuable, personalized content that avoids spam triggers. Stay compliant by following best practices, and you’ll boost engagement without landing in the spam folder.
Avoiding Spam Trigger Words and Phrases
We’ve all been there-spending hours on the perfect BFCM email, only for it to end up in the spam folder. What went wrong? Often, it’s the spam trigger words.
Common spam trigger words to avoid:
- “Free”
- “Guaranteed”
- “Limited time”
- “Winner”
- “Earn money”
- “Urgent”
Spam filters flag these words because they’re associated with shady or over-sell tactics. So, how do you get past the filters and still grab attention?
Tips for crafting spam-free content:
- Get creative: Instead of “free shipping,” try “complimentary delivery” or “exclusive offer“.
- Be personal: Instead of sounding salesy, focus on words like “early access“, “just for you” or “savings tailored to your needs.”
- Create curiosity: Try using subject lines like “Your early access to BFCM deals” rather than “Buy now, save big!“
Spam filters love authenticity. So, personalize your emails and avoid sounding like a generic sales pitch!

Ensuring Clear Unsubscribe Options
No one likes being stuck with unwanted emails. That’s why you need to make unsubscribing as easy as possible. And it’s not just about being nice-it’s the law.
Legal requirements for opt-out options:
- You must include an unsubscribing link in every email.
- The link should be clear and easy to find—usually at the bottom of the email.
Best practices for maintaining trust:
- Make the unsubscribe process simple-don’t hide it!
- Add an optional feedback form asking why they’re unsubscribing. It helps you learn and improve!
- Offer an option to opt-down (reduce frequency) instead of fully unsubscribing. It keeps people in your audience!
When people feel in control, they’ll trust your brand more. Plus, a simple unsubscribe process helps your email reputation stay intact!
Monitoring and Optimizing Email Performance
Track key metrics like open rates, CTR, bounce rates, and spam complaints to gauge your BFCM email success. Use this data to fine-tune your content, adjust sending frequency, and target the right audience for better results.
Tracking Key Engagement Metrics
Picture this: You’ve just hit “send” on your BFCM email campaign, and now you’re waiting for the sales to roll in. But there’s a crucial step you can’t skip-tracking your email performance. To ensure your emails land in inboxes and drive conversions, you need to keep a close eye on metrics like open rates, click-through rates (CTR), bounce rates, and spam complaints.
- Open Rate: This tells you how many recipients actually opened your email. A low open rate could mean your subject line needs tweaking or your emails are getting lost in spam folders.
- Click-Through Rate (CTR): This shows how many people clicked on your links within the email. If your CTR is low, it might be time to reassess your call to action (CTA) or the layout of your email.
- Bounce Rate: High bounce rates? That’s a red flag. It could mean your email list needs some cleaning up-removing invalid or outdated addresses.
- Spam Complaints: The ultimate metric for deliverability. If people are marking your emails as spam, it’s time to rethink your content or the frequency of your campaigns.
To track these metrics, tools like Google Analytics, Klaviyo, Retainful, Omnisend are perfect for digging into the data and getting actionable insights. These platforms can give you a clearer picture of what’s working and what’s not, allowing you to adjust before your next big email blast.

Adjusting Strategies Based on Performance Data
Now that you’ve tracked your metrics, the real work begins-optimizing your strategy. Here’s how you can use these insights to refine your emails for better results:
- Refine Email Content: If your open rates are low, experiment with different subject lines. A/B testing is your best friend here. A more compelling subject line can mean more eyes on your email.
- Adjust Sending Frequency: Is your bounce rate climbing or are people unsubscribing? Perhaps you’re sending too many emails. Use your metrics to determine the sweet spot for your audience-whether that’s one email a day or just once a week.
- Targeting: Not all subscribers are the same. If your CTR is low, consider segmenting your audience based on past purchases or engagement level. Sending the right message to the right person can increase conversions dramatically.
