Every November, shoppers wait for Black Friday deals. Brands fill inboxes with discounts and promotions. But there is another kind of email that brings in a lot of sales – automated and transactional emails. These are the messages that go out when a customer takes an action, like placing an order or leaving a cart behind.

Research shows how powerful these emails are:

• One in three people who click an automated email make a purchase
• Automated emails make up only 2% of total sends but bring in 37% of sales
• Abandoned cart, welcome, and browse abandonment emails create most automated orders

These numbers prove that people pay attention to emails tied to their behavior. They open them, they read them, and they often buy.

Why Email Still Works During Black Friday

When Black Friday hits, shoppers look at their inbox for deals and updates. They expect to see discounts, order confirmations, and shipping notices. Other channels like ads and social media play a role, but email is where customers turn when they are ready to take action.

Automated Emails That Matter Most

Here are four types of emails that make a big impact during Black Friday:

1. Order Confirmations and Shipping Updates

• Open rates average close to 50%
• Customers check these emails for reassurance about their order
• Adding product suggestions inside these emails can increase sales

2. Abandoned Cart Emails

• Many shoppers leave items in carts during Black Friday
• A quick reminder often brings them back
• Offering a small discount in the reminder can help close the sale

3. Low-Stock and Price-Drop Alerts

• Customers respond when an item they viewed is almost gone
• A price-drop email feels helpful and gives them a reason to act fast
• Keep the message short and clear

4. Browse and Wishlist Reminders

• Some shoppers browse without adding items to their cart
• Reminders about products they viewed can bring them back
• These messages are personal and often turn interest into sales

Journeys That Build Stronger Results

Promotional blasts bring in quick sales, but automated journeys continue to work in the background. They help new customers get to know your brand and guide them toward more purchases.

Welcome Journeys

• Send a series of 2–3 emails to introduce your brand
• Share bestsellers and what makes your store different
• Encourage people to update preferences so you can send relevant offers

Post-Purchase Journeys

• Say thank you within 24 hours of the order
• Share tips for using the product a few days later
• Suggest a related product within the first two weeks

Cross-Sell and Upsell Journeys

• Holiday shoppers are open to buying more than one item
• Suggest products that complete a set or bundle
• Use social proof like “customers who bought this also liked…”

During Black Friday, shorten the timing of these journeys. Send welcome messages quickly. Deliver post-purchase and upsell emails within days, not weeks.

Make Sure These Emails Reach the Inbox

Automated and transactional emails follow the same rules as promotional emails. They need to pass through spam filters and protect your sender reputation.

Here are three key steps:

• Set up SPF, DKIM, and DMARC to confirm your domain identity
• Keep frequency reasonable and avoid sending too many triggered messages
• Write subject lines that match the purpose of the email

Test and Monitor During Black Friday

High email traffic during Black Friday can cause problems. Automated does not mean risk-free.

Check these areas before and during the big week:

• Test how emails look on different devices and in Dark Mode
• Track inbox placement to confirm your emails are delivered
• Focus on click-to-conversion and complaint rates, not just open rates

FAQs About Automated Emails

The Emails That Do the Quiet Work

Promotions will always be part of Black Friday. But the automated and transactional emails are the ones that build trust and capture missed revenue.

• Confirmation and shipping emails give customers peace of mind
