Best practices, design tips, and tools for high-impact email signatures

Ever glance at an email signature before reading the actual content of the message?  

You’re not alone. Email signatures serve as a stamp of credibility—a quick way to judge who the email is from, what it’s about, and whether it’s worth your time (sorry, not sorry). 

But a strong e-signature is more than just a name, a scribble, and a few links. It’s prime real estate for building trust and driving action. With the right approach, every e-signature becomes a brand touchpoint that reinforces your identity, generates leads, and ensures compliance. 

In this article, we’ll explore what to include in your email signatures, the best tools for the job, and how to implement them company-wide. 

What to include in your e-signature

We’ve broken down the essentials into three key areas: contact details, marketing opportunities, and compliance essentials.

Step 2: Brand and marketing opportunities

The average office worker sends 40 emails daily and receives 121 (The Guardian)—that’s thousands of opportunities each month to promote your latest campaign and generate new leads. And it works: personalized signatures boost click-through rates by 14% and conversion rates by 10% (Webfx). 

Despite this, e-signatures remain a largely untapped marketing channel, with only 18.8% of professionals using them for lead generation (WiseStamp). 

Ways to maximize your e-signature: 

• Promote campaigns: Running a webinar or launching a new product? Use a clickable CTA like “Join our next webinar” or “See what’s new.” 
• Strengthen brand consistency: Standardize logos, fonts, colors, and taglines to ensure every email looks professional and on-brand. 
• Share thought leadership: Link to a blog, report, or whitepaper that showcases your expertise. 
• Highlight events: Use a branded event banner or link to increase visibility and engagement. 
• Showcase your product: A tagline like “See how [Company Name] helps teams work smarter” keeps your value proposition clear. 
• Leverage social proof: Mention awards, media features, or testimonials to build trust. 
• Track performance: Add UTM tracking to signature links to measure engagement and optimize accordingly. 

Pro tip: Keep marketing elements subtle, relevant, and updated. An outdated promo or off-brand element can do more harm than good. 

Step 3: Compliance essentials

Depending on your industry, your email signature might need to meet legal and regulatory requirements. 

Some industries, like finance, law, and healthcare, require specific disclaimers or confidentiality notices to protect sensitive information. Even if it’s not mandatory, a short compliance statement can add credibility and clarity. 

Consider including: 

• Confidentiality disclaimers: Useful for legal, financial, and healthcare firms. Example: “This email and any attachments may contain confidential information. If you’re not the intended recipient, please notify the sender and delete this email immediately.” 
• Regulatory compliance: If your industry requires disclosures (e.g., GDPR, HIPAA), add a short compliance note with a link to your full policy. Example: “We comply with GDPR regulations. View our privacy policy.” 
• Company registration details: In some countries, businesses must include legal details in official communications, such as a registered company name and number. 
• Terms of use and liability waivers: If your emails include recommendations or advice, a small disclaimer can protect your business. Example: “This email doesn’t constitute legal advice. Please consult a professional for specific guidance.” 

Pro tip: Keep legal disclaimers concise—no one reads a 10-line block of fine print. Link to a full policy if needed. 

Top 5 email signature tools based on your needs

Choosing the right email signature tool depends on your specific requirements. Whether you’re a freelancer aiming to enhance your branding or an enterprise seeking centralized control, there’s a solution tailored for you. 

Here are some top options: 

Best practices for an optimized e-signature

There are plenty of elements you could include in an email signature, but you can’t (and shouldn’t) have them all. Here are some best practices to follow to make sure your e-signature packs the best punch. 

1. Keep it concise 

People tend to skim emails, so a lengthy signature can lead to important details being overlooked. Focus on including only the essentials to guide recipients toward the desired action.  

2. Optimize image sizes 

Large images can slow down email load times, especially on mobile devices, or may not display correctly. Ensure that any images in your signature are optimized for quick loading and proper rendering across all devices.  

3. Design for mobile devices 

Nearly half of all emails are opened on mobile devices (Hubspot), so it’s crucial to ensure that your signature is mobile-friendly. Use a single-column layout, legible fonts, and test your signature across various devices to ensure readability.  

4. Choose a single, clear call-to-action (CTA) 

Emails with a single CTA have a 42% higher click-through rate (WordStream). 

Overloading your signature with multiple links can dilute attention. Instead, choose one clear CTA that aligns with your goals, whether that’s “Book a demo,” “Download our latest report,” or “Follow us on LinkedIn.” 

5. Regularly update your signature 

One third of professionals (31.6%) only update their email signatures every few years (Hubspot), missing opportunities to plug campaigns and keep communication fresh. 

Things like outdated job titles, incorrect contact details, old logos, and old marketing campaigns erode credibility. Update regularly to ensure your signature reflects the latest branding, messaging, and promotions. 

The smartest way to keep email signatures current is through centralized management. Tools like Templafy automate and standardize signatures across the company, ensuring every employee’s email is on-brand, up to date, and optimized to drive results.
