If you’re not using employee emails to support your seasonal marketing campaigns, you’re missing a key opportunity.
Every one-to-one email—whether it’s sent by Sales, Support, or HR—is a direct line to a customer, partner, or prospect. And with the right email signature, it’s also a space to drive clicks, increase awareness, and boost conversions.
In this post, we’ll explore how to use email signatures to support your Black Friday marketing campaign, what makes a great seasonal signature, and how Exclaimer helps you manage them at scale without adding to IT’s workload.
Why Black Friday campaigns shouldn’t stop at email marketing
Black Friday is a short window with big potential. It’s one of the busiest email days of the year—116.5 million emails messages typically sent, and marketing emails leading the pack for opens and clicks.
And with 88% of users checking their inboxes multiple times a day, it’s one of the best chances to make every message count. Marketers can’t afford to leave any channel underused—including email signatures.
Email signatures are one of the simplest ways to extend your reach. They show up on every one-to-one email your employees send, turning everyday business communication into a high-impact marketing channel.
Every employee sends dozens of emails per day. That adds up to thousands of annual impressions.
Email signatures can carry clickable display banners, discount messages, or promotional CTAs.
Consistent signatures across teams reinforce brand recognition and campaign messaging.
Most Black Friday campaigns focus on outbound efforts: paid ads, promotional emails, and social posts. While these have their place in any marketing strategy, they’re easy to ignore. Promotional messages may land in junk folders or get buried in crowded inboxes.
Business email is different. It’s direct. It’s expected. And it usually gets read. That makes the email signature space the perfect place to include a seasonal offer.
If you’re spending on Black Friday campaigns, make sure your everyday emails are part of your plan.
Why employee email signatures work for Black Friday promotions
There’s no subject line to optimize. No spam filter to dodge. No question whether it landed. That’s why 94% of marketers say consistent, branded email signatures help boost engagement.
A Black Friday email signature appears on every ordinary email your teams send, which external recipient will see.
Here’s why it works:
Built-in visibility: It’s part of every email, so it gets seen.
Low friction: Feels like part of the conversation, not a sales pitch.
Works fast: Ideal for flash sales and limited-time offers.
Doesn’t interrupt: It’s subtle, not disruptive.
Works everywhere: Sales, Support, HR—every team adds reach.
Unlike other marketing channels, email signatures work across the entire funnel. They build awareness, support conversion, and drive post-sale engagement. And all without needing a separate campaign.
What to include in a Black Friday email signature
A good email signature for Black Friday combines brand consistency with a clear promotional message.
Here’s what to include:
Campaign banner: A visual that communicates the offer clearly—like “Up to 50% off, this week only.”
CTA button: Direct traffic to your landing page, product catalog, or limited-time deal.
Brand elements: Align your fonts, colors, and logos with your campaign and company guidelines.
Legal disclaimers: Include a short line or link to the T&Cs if your discount has them.
Extras: Include optional social icons and UTM tracking to help you evaluate the success of your Black Friday signatures.
Pro tip: Design for mobile first. The majority of business emails are opened from mobile devices.
Black Friday email signature examples
Need inspiration? Here are a few Black Friday email signature examples tailored for different departments:
1. Customer Success
Designed to stand out, this signature combines a bold “Up to 25% off all products” message with a sharp dark background and a high-contrast red CTA button. The addition of a Black Friday-themed shopping bag reinforces the retail focus.
2. Sales
This email signature example makes the Black Friday offer impossible to miss. A bold black and gold theme grabs attention, while the floating confetti adds energy without distracting from the message. A clear discount code and prominent “Shop Now” button drive clicks straight to the sale.
3. Support
If you’re happy with your current layout, there’s no need to start from scratch. Just swap in a Black Friday banner to highlight your seasonal offer. It’s a quick update that keeps your signature consistent while still promoting the campaign.
You can also rotate different banners by team, target audience, or campaign stage. Launch a teaser banner a week early, switch to your main offer during the sale, then promote gift guides or year-end deals after.
Deploying seasonal email signatures at scale
