Is your email program ready for Black Friday?

Black Friday falls on November 27 this year and Cyber Monday on November 30. The work that protects those weeks happens now, while there is still time to test calmly.

Start with what is already running.

Before planning a single campaign, list every automated flow that will keep sending during the season: welcome, browse and cart reminders, post-purchase, win-back, and anything a past app installed. Open each one. Check the trigger, the delays, the exit conditions, and the offer it mentions.

The most common seasonal problem is not a missing campaign. It is an old automation quietly contradicting the new one: a welcome series promising 10% off while the sitewide sale is 25%, or a cart reminder sending a code that expired last spring.

Confirm your sending basics.

Gmail and Yahoo now expect bulk senders to authenticate their mail with SPF, DKIM, and DMARC, to offer one-click unsubscribe, and to keep spam complaints low (Google's published threshold is 0.3%, with a lower target recommended). Ask whoever manages your email platform to confirm these are in place for the domain you actually send from.

Then look at who you plan to mail. Sending suddenly to every address you have ever collected, including people who have not opened or clicked in a long time, raises the risk of complaints exactly when inbox placement matters most. Decide your engagement window now, and if you want to re-include older contacts, bring them back gradually in the weeks before the peak.

Write the offer rules down.

• What exactly is discounted, and what is excluded?
• When does it start and end, in which time zone?
• Can codes stack with existing subscriber or loyalty offers?
• What happens to customers who bought at full price last week?

A one-page offer sheet that support, email, ads, and the site all use prevents most seasonal confusion. It also tells you which existing flows need a temporary pause or a new branch.

Check the promises after the click.

Email can create demand faster than operations can absorb it. Confirm stock on featured products, your carriers' holiday shipping cutoffs, and the wording on product pages and checkout about delivery timing. Promotional emails should not promise arrival dates your fulfillment cannot keep.

Test like a customer.

Create test profiles that enter each important flow. Click every link, apply every code, and complete a purchase where possible. Check the mobile rendering, the plain-text version, and what happens when someone buys mid-sequence: they should exit the cart reminder, not receive it again.

Decide what you will measure.

Platform-attributed revenue will spike in late November whether or not a specific email changed anything. Before the season, write down the few numbers you will actually compare afterwards: orders and revenue against the same period last year, discount cost, unsubscribe and complaint rates, and contribution after discounts and shipping. That comparison is what tells you whether the season was worth what it cost.
