Email Signature Best Practices for Cold Outreach Campaigns

When it comes to cold email outreach, the devil is literally in the details. From the subject line to the body copy, your message should immediately call attention and build trust. One detail often forgotten that actually has a huge role is the email signature. While it may seem like a small detail, a fantastic email signature can have a huge effect on the success of your outreach.

Did you know that only 8.5% of cold emails get replies? All the more reason to pull out all the stops in trying to get an answer. A good business email signature enhances your brand, gives people information about you and your business, and facilitates people taking action. It sends a powerful reputation signal that not only helps in establishing trust but also in being seen as a legitimate, reputable sender. After all, in the dog-eat-dog realm of cold emailing, the small touches can make a big difference.

In this post, we will leave no stone unturned when it comes to creating an email signature that’s tailor-made to your cold outreach campaigns. We’ll cover the key details to include, offer a little inspiration, and give you some actionable tips to make sure your email signature is working for you.

Key elements of a high-performing email signature for cold outreach

Your email signature is usually the last thing someone sees, yet it demonstraes the professionalism and the kind of brand you’re representing. In this section, we will dissect the key components that form a high-performing email signature for your cold outreach campaigns.

Essential contact information 

At the very least, we’d recommend that your email signature should feature your name, title, company, and a phone number that prospects can contact you at. So this important data adds credibility and provides the person a means to contact you directly and hence (hopefully) get a response.

So why is clear contact information essential for credibility? Including these basic information shows transparency and helps potential leads feel more comfortable engaging with you. 

Tips for formatting contact info for easy reading:

• Use simple, clear text. Avoid long strings of information that are difficult to read or understand.
• Separate details logically. Group your name, title, company, and contact info into distinct lines.
• If relevant you might also want to include socialmedia links as well so they can reach out to engage with you in other ways (e.g. LinkedIn).

Example:

John Doe
Sales Manager | ABC Corp
Phone: +1 (123) 456-7890
LinkedIn: linkedin.com/in/johndoe

Consistent branding

HubSpot says that branding and awareness are the primary goals for using email signatures. Your email signature should align with your overall branding. Since this is the finishing touch, this will help reinforce your brand identity even more.

Your email signature, similar to website and social media profiles, should showcase your company in brand colors and with your company logo and fonts, creating continuity and a professional experience.

• Use your brand’s colors and logo in your email signature. Not only does this help establish brand identity, it makes your emails look pretty and easily recognizable too.
• Stick to your company’s font for consistency, ensuring the signature feels like an organic extension of your email’s tone and style.
• Ensure that the design and language of your signature are consistent with your website and other online channels. This cohesiveness helps build a stronger connection with recipients, who are more likely to trust your brand when everything looks unified.

Example:

A simple email signature for a SaaS company could look like this:
Jane Smith
Customer Success Manager | XYZ Software
Phone: +1 (987) 654-3210
Visit our website: xyz.com
Follow us: LinkedIn | Twitter

Links and images

So while it’s often tempting to put several links, logos, or images into your email signature, too many elements can easily confuse the recipient, and essentially water down the message you’re trying to send. Extra links (like numerous social profiles) extra large images, and so on can flag spam filters and distract from the purpose of the email.

Best practices for including just the essentials:

• Only include the most relevant links (3-5 should be okay), such as your company’s website or your LinkedIn profile.
• Avoid using too many images, save for perhaps your logo or a small, professional icon if necessary. Ensure images are optimized for fast loading times, as large or unoptimized images may cause deliverability issues.
• Prioritize clarity. Avoid excessive use of colors, fonts, and buttons in your signature. Stick to a clean, readable format.

Example of a clutter-free signature:

Tom Andrews
Founder | Alpha Marketing
Phone: +1 (555) 123-4567
Website: www.alphamarketing.com

In this case, there’s no unnecessary clutter. The key contact information is cleanly presented, and only the most relevant links are included.

Clear and readable layout

Formatting matters a lot when it comes to your email signature. A messy or illegible signature could cause your email to appear unprofessional—which could also hurt your credibility. Formatting improves the look, professionalism, and trustworthiness of the document.

Here are some best practices when it comes to layout:

• Font size and type: Choose a simple, professional font like Arial or Calibri, and stick to a font size of 10 and 12 points. Anything too big or too small can throw off the balance in your email.
• Spacing: Use appropriate line spacing and avoid cramming all information into one line. Keep enough space between different pieces of information so it’s easy for the recipient to scan.
• Avoiding over-complicated layouts and excessive information: Your signature should be as simple as possible while still providing all necessary details. The goal is to make it easy for the reader to identify your contact details, quickly navigate to relevant links, and feel confident in your professionalism.
• Optimize for mobile. A significant portion of your cold emails will be read on mobile devices. In fact, 41.6% of emails are opened via mobile. A signature that looks great on desktop might look jumbled on a small screen if it’s not optimized for mobile. Ensure that your signature remains clear and readable on any device.

A Calls to Action (CTA) that drives action

Your cold email signature is a great location for a call to action (CTA). Just be sure that the CTA is subtle and that it doesn’t force something on your audiences. It could be something as basic as “Let’s set up a call” or “Click here to find out more.” You want the recipient to feel compelled to want take the next step (in sales) without feeling persuaded.

Tip: The most important rule in your CTA is to keep it as simple and as clear as possible—and ideally, the CTA should be directly related to the purpose of the email

Example:

Tom Andrews
Founder | Alpha Marketing
Schedule a quick call: [Insert Calendar Link]
