In today’s digital world, successful businesses must effectively and consistently present their brand identity across multiple platforms, including their website, sales collateral and social media.

However, despite being the most frequent form of communication (with the average employee sending approximately 40 emails per day), the need to present a strong brand identity over email is often overlooked.

An email signature is a critical part of your business’s corporate identity; it captures your brand values, and if you get it right, can strengthen credibility with your prospects and clients.

Not only should your email signatures be on-brand and consistent, but they also must remain data and legally compliant to stay aligned with industry regulations and standards, particularly if you’re in the financial services sector.

But what is the easiest, most impactful way to manage company-wide email signatures in Outlook?

Chloe Stevens, Content Marketing Manager at UpSlide will walk you through how to manage company email signatures in Office 365.


  • There are three ways to manage your company’s email signatures in Outlook: Ask employees to do it manually – this option comes with no cost, but it’s time consuming and could result in damages to your brand.

  • Use Microsoft 365 admin center. This option is only available to the Microsoft admin in the business (usually IT) and requires HTML knowledge.

  • Choose an external Outlook signature manager. While this solution comes at a small cost, it ensures long-term ROI via increased productivity and guaranteed brand consistency.

The benefits of effectively managing email signatures in Outlook

  • Strengthening your brand image: Well-crafted, professional email signatures reflect your company values and reinforce your brand reliability.
  • Ensuring brand consistency: A cohesive visual identity across all employees’ Outlook signatures strengthens brand recognition and messaging.
  • Maintaining data accuracy: Always presenting up-to-date employee information helps boost credibility and professionalism.
  • Guaranteeing legal compliance: Including necessary disclaimers or privacy statements mitigates risk by ensuring legal compliance.
  • Maximizing marketing and sales opportunities: Email has the potential to be a powerful marketing channel if you leverage branded campaign banners and targeted, tailored signature banners.

Three ways to manage email signatures in Outlook

Ask employees to do it manually

A low-cost option is to rely on each employee to create their own email signature manually. If you’re thinking about adopting this process, follow the steps below:

  1. Create a template signature in Word that includes your correctly-formatted logo, font and any legal disclaimers.
  2. Send the email signature template to each new employee to copy and paste into Outlook’s native signature settings.
  3. Trust them to correctly insert it and manually update it each time any detail changes, whether it be your office address or graphic charter.
  4. Encourage them to add and hyperlink marketing banners as you launch new campaigns.

What to consider with this email signature management solution:

Choosing this option will leave your business open to brand and legal risk; here’s why:

  • If employees fail to accurately update their email signature with the correct font size and color, up-to-date logo, legal disclaimer and marketing banner, it could leave a poor impression of your business for external recipients.
  • Sourcing relevant content for their email signatures is time-consuming and extra responsibility for employees.
  • It’s inefficient for the person managing email signature templates to regularly communicate these changes when they occur.

Create a company-wide email signature via Microsoft 365 admin center

Microsoft enables business admins (usually IT teams) to create a company-wide email signature, including a legal disclaimer and logo.

NOTE: Microsoft calls their organization-wide signatures “disclaimers,” regardless of what they include. For example, they can be a signature or include your address, legal disclaimer, or other information you want.

Follow these steps:

  1. In the Microsoft 365 admin center, select Exchange.
  2. Select Mail flow.
  3. Select Add +, and then select Apply disclaimers.
  4. On the New rule page, enter a name for the rule (e.g. your company name) and select [Apply to all messages] in the *Apply this rule if… drop-down.
  5. On the *Do the following… drop-down, verify that Append the disclaimer is displayed. Then select ‘Enter Text’ and enter the text for your email signature.
  6. Improve the look of your signature by formatting the text with HTML.
  7. If you want an image in your signature, like your company logo, copy and paste a publicly available URL to that image into the disclaimer.
  8. Scroll to the bottom of the New rule and click Save, then ‘Yes’ to apply this rule to all future messages.

NOTE: When you go to send your next email, you cannot preview the email signature in Outlook. However, your recipients will see it.

What to consider with this email signature management solution:

  • You and your colleagues must have 365 licenses to benefit from this Microsoft functionality. The minimum cost is £6.60 user / month (not including VAT.)
  • Only the Microsoft admin in the business (usually someone in IT) can access and create Outlook signatures. They are solely responsible for updating them across the company, which takes up valuable time and resource.
  • Creating the email signature within the Microsoft admin center is complicated. You must be comfortable using HTML to format your signature correctly without the option to insert your logo or marketing banner quickly.
  • Plus, this option does not allow you to preview the Outlook signature before or after deployment, so you risk distributing a poorly-formatted email signature.

Choose an external Outlook signature manager to optimize employee communication

Investing in an external tool is a good option as it does all the work for you. With UpSlide’s Outlook Signature Manager, you can guarantee your entire business delivers on-brand, impactful emails every day. Here’s how it works if you’re an admin:

  5. Preview your signature campaign on the right side of the pane, click ‘Ok’ and enjoy instant deployment!
  6. Be confident that Outlook Signature Manager is synced with Azure Active Directory, so it will automatically refreshed as Azure is updated – for example, if someone receives a promotion or moves office.
