Most companies have never systematically checked what their outgoing emails actually look like to recipients. Every day, your staff send hundreds of messages to clients, partners, and prospects, which means a broken layout or an outdated disclaimer reflects directly on your business reputation.
Five Steps to Review Your Company Emails
Step 1: Gather a Cross-Section of Test Emails
To start your review, ask five employees from different parts of the business to send you a test email. Pick people from across the business, for example sales, finance, HR, customer support, and marketing, so you get a fair cross-section of the templates currently going out.
Step 2: Check Rendering Across Devices
Once the emails arrive, open them on both a desktop computer and a mobile phone. You need to check how the formatting holds up across different email clients, specifically Gmail, Outlook, and Apple Mail. A signature that looks perfectly aligned on a desktop monitor often becomes completely broken on a small smartphone screen.
Step 3: Verify the Legal Details
Next, look closely at the legal details in the disclaimer. Every business email sent on behalf of a UK limited company must display details that match its Companies House record, including the registered name, company number, registered office address, and place of registration. These requirements are set out in Part 6 of the Company, Limited Liability Partnership and Business (Names and Trading Disclosures) Regulations 2015, and apply to business letters, order forms and websites in any format.
Step 4: Compare Old and New Signatures
Compare the email signature of your oldest employee with the signature of your newest hire. This usually reveals how much your brand design has drifted over time as people edit their own settings.
Step 5: Decide Whether You Can Manage This Manually
Once headcount climbs past a couple of dozen, manual updates start to slip through the cracks, which is why larger teams move to dedicated business email signature management systems to keep control. Checking everything manually will give you a clear picture of where the weak spots are.
What to Check During Your Audit
Before you start, here’s what to look for. The first two items are legal requirements for UK limited companies and LLPs. The rest are brand and operational checks that protect your reputation.
Legal compliance
- Company registration:Â Registered company name, company number, registered office address, and place of registration (England and Wales, Scotland, or Northern Ireland). These must appear on business emails under UK company disclosure requirements.Â
- Privacy information: A link to your current privacy notice. Not required by the Companies Act, but strongly recommended under UK GDPR transparency obligations.
Brand and Operational Checks
- Brand consistency: Correct logo version, approved brand colours, and standard fonts.
- Contact accuracy: Valid phone numbers, active links, and correct job titles.
- Mobile rendering: Clean layout on small screens with no overlapping text or broken images.
- Marketing banners: Up-to-date call-to-action links and active promotional graphics.
Three Options to Fix Broken Signatures
Option 1: Manual Fix
You send updated HTML code or text templates to your staff and ask them to paste the details into their email settings. It costs nothing in software, but it depends entirely on employee compliance. In practice, manual updates tend to break down once a business grows past roughly 20 staff, since people forget to apply the changes or paste the template incorrectly.
Option 2: Client-Side Plugin
The software installs onto each user’s computer and updates the signature automatically. It gives you more control than a manual setup, but you still need to install it on every machine. It costs a few pounds per user each month and often struggles with mobile devices that do not support local plugins.
Option 3: Server-Side Deployment
The system adds the correct signature to the email after it leaves the user’s device but before it reaches the recipient. Because the signature is added server-side rather than on the user’s device, the rendering is consistent for every recipient, including those reading on mobile. It runs on a small monthly subscription per user, and it removes human error from the process entirely.
What the Audit Tells You
A thirty-minute audit will not solve every signature issue, but it shows you where the gaps are and how much drift has built up over time. Pick the fix that matches your headcount, and you stop sending mixed signals about who your business is.
