10 strategies for increasing user engagement with business email signatures
Key takeaway
To use employee email signatures for brand promotion, put a targeted banner under each one and make sure every employee sends the same approved version.
Email signature content averages a 4% click-through rate across Exclaimer customers, according to Exclaimer customer data.
In Exclaimer's 2026 survey of 1,000 US adults, 23% said a professional, branded email signature makes a company email feel more trustworthy.
Every strategy here needs a consistent email signature, and 80% of the IT professionals in Exclaimer's State of Business Email 2025 survey say their organizations rely on manual methods or user self-service.
Every email an employee sends can carry a business email signature, whether or not anyone has designed one. Used well, it can earn clicks, follows, survey responses, and booked meetings. Email Signatures for Dummies goes deeper.
1. Provide actionable content
Full contact details were the strongest trust signal in Exclaimer's 2026 OnePoll survey of 1,000 US adults, cited by 40%.
Put the name, job title, direct number, and website in the email signature, plus a link to the page most contacts want next, such as a pricing page or a booking page.
Our guide to employee contact details in email signatures covers what belongs there.
2. Promote brand awareness
Every email with a branded email signature puts your logo and colors in front of the recipient. In the same survey, 23% said a professional, branded email signature makes a company email feel more trustworthy. That put it ahead of legal disclaimers (17%) and consistent formatting (16%).
That only holds if every employee sends the current logo. The design side is covered in our email signature branding. guide.
3. Ensure legal compliance
Ed Bodey, General Counsel at Exclaimer, says email signatures and disclaimers "carry mandated information in several jurisdictions and industries, and that information is often determined by regulatory requirements."
A disclaimer in the email signature can carry that text. Exclaimer applies disclaimers on the server by rule, per user, region, brand, or audience, so employees can't edit or remove them. Your legal team should approve the wording.
For what to include, see our email disclaimer guide.
4. Encourage social media engagement
Add icons that link to your company's LinkedIn page and other social profiles.
On Exclaimer's Pro plan, the email signature can also show the latest LinkedIn posts. Carly Papadopoulos, Senior Product Manager at Exclaimer, says the audience is the point: "You're emailing the exact audience you want looking at your content, customers, partners and prospects, not random social traffic."
5. Align your marketing and promotions
A banner under the email signature can promote an event, a new product, an offer, or a discount. Exclaimer's Campaigns feature targets a banner by recipient, sender, department, or region, and can use HubSpot or Salesforce lists, so an offer for existing customers doesn't reach prospects.
In Exclaimer's own account-based marketing campaigns, targeted email signatures typically drew 15 times the click-through rate of display ad campaigns.
Time-limited promotions can be scheduled with start and end dates. On the Standard and Pro plans, one email signature can hold up to 15 rotating banners.
Shearwater Geoservices, a marine geoscience company with 1,200 employees, reports more than 1,000 visitors a month to a campaign landing page through email signature banners. Who can launch a banner and who approves it is covered in our guide to email signature marketing dos and don'ts.
6. Encourage customer feedback
Add a link to a one-question survey or star rating to the email signature of customer-facing teams such as support and account management. The survey link sits in an email the customer is already reading.
Email signature surveys walks through the setup.
7. Increase employee advocacy
When every employee's email signature carries the same logo and links, each email represents the company the same way.
Sharon Handy, Director of People Experience at Exclaimer, says, "If you don't have a standard system, people get creative. You can have someone calling themselves account director when their actual title is account executive. That causes confusion, but also potential liability in who the customer thinks they're dealing with."
Directory sync fills in names and job titles from Microsoft Entra ID or Google Workspace Directory, so the details stay current without employees editing anything.
The same space works internally. Handy describes using a banner on internal email for well-being campaigns, links to the employee assistance program, recognition, and benefits enrollment reminders.
8. Make support easy to reach
Put a support link and a booking link in the email signature of customer-facing teams, so a customer can reach support or book time with an account manager from any email.
Exclaimer integrates with meeting-booking tools such as Calendly and Microsoft Bookings.
9. Showcase achievements and accolades
Awards and certifications give a recipient something to check, and a banner is a natural place for them. Schedule each one with an end date so an old award doesn't stay in place after a new one arrives.
10. Show support for a cause
Link to your sustainability policy or to a charity fundraiser the company is backing.
Promoting sustainability with email signatures has more on presenting those efforts.
How to tell if it's working
Across Exclaimer customers, email signature content averages a 4% click-through rate, according to Exclaimer customer data. Treat it as a rough yardstick, because banners, audiences, and click-through definitions vary.
Compare your banners with it and with the click-through rate on your own marketing email. A banner well below both is worth testing with a different message or audience.
Tip
Add UTM (Urchin Tracking Module) parameters to every banner link.
As Google Analytics Help explains, the parameters travel with the click, so you can see which campaigns sent the traffic. Exclaimer's analytics, on the Pro plan, report click-through rates and engagement.
What has to be in place first
Every strategy above assumes recipients see the email signature you designed. In Exclaimer's State of Business Email 2025 research (Censuswide, April 2025, 4,009 IT professionals in the UK, US, Germany, and Australia), 80% said they rely on manual methods or user self-service for email signatures. Only 20% use a dedicated email signature management solution.
"A branded email signature is a trust signal you can reliably place on every single email if it's centrally governed. If it's not, you're at the whim of each sender, it's different mailbox to mailbox, and that inconsistency detracts from credibility. The recipient notices the variation even when the sender never does."
Company-wide, the email signature needs:
One approved design applied to every employee email
Names and job titles filled in from a company directory that someone keeps accurate
Disclaimers that employees can't edit or remove
Banners that marketing can change without an IT ticket, within limits IT sets
Click and engagement reporting
A new office, a new market, or a company acquired under its own brand can each need its own logo and legal text in the email signature, applied by region or business unit.
Gunnebo Entrance Control now updates every region in minutes without involving IT. It reports 100% brand consistency across its regions and 1,000 to 2,000 banner clicks a month.
Run it from one place
Exclaimer integrates with Microsoft 365, Google Workspace, and Microsoft Exchange. IT sets the permissions and the rules, and marketing can build templates and run banner campaigns within them.
Brand Kits hold approved logos, fonts, colors, and banners in one place, so a rebrand updates every email signature that uses the kit.
