Why Roundcube Email Signatures Matter for Your Business
Roundcube is one of the most widely used open-source webmail clients in the world. If your organisation relies on cPanel, Plesk, or DirectAdmin hosting, chances are your team members access their email through Roundcube every day. Yet many businesses overlook a critical branding opportunity: the email signature.
A well-crafted email signature does more than close off a message. It reinforces your brand identity, ensures legal compliance (especially important under European regulations), and provides recipients with essential contact information. For Belgian and European B2B companies, a consistent, professional signature across all employees is not a nice-to-have — it is a business necessity.
In this complete guide, we will walk you through setting up email signatures in Roundcube, discuss the limitations you may encounter, and show you how to overcome them with centralised signature management.
How to Set Up an Email Signature in Roundcube
Step 1: Log Into Roundcube Webmail
Access your Roundcube webmail interface through your hosting provider. This is typically available at webmail.yourdomain.com or through your cPanel, Plesk, or DirectAdmin dashboard. Enter your email address and password to log in.
Step 2: Navigate to Settings
Once logged in, click on the Settings icon (gear icon) in the left-hand sidebar or top navigation bar. This opens the configuration panel where you can manage your account preferences.
Step 3: Open the Identities Section
In the Settings menu, click on Identities. Here you will see your default email identity listed. Click on it to edit, or create a new identity if you manage multiple email addresses or aliases.
Step 4: Create Your Signature
In the identity editor, scroll down to the Signature field. You have two options:
- Plain text signature: A simple text-based signature without formatting. Reliable but limited in branding potential.
- HTML signature: A rich signature with formatting, colours, images, and links. To enable this, tick the checkbox labelled "HTML signature" above the signature editor.
For a professional B2B signature, we recommend using an HTML signature. A standard business signature should include:
- Full name and job title
- Company name and logo
- Phone number and email address
- Website URL
- Registered company information (required in many EU countries)
- Optional: social media links, a promotional banner, or a legal disclaimer
Step 5: Format Your HTML Signature
Roundcube's built-in editor provides basic formatting tools such as bold, italic, font selection, and colour options. However, if you want a more polished design, you can create your signature in an external HTML editor and paste the code directly into the signature field.
Keep these best practices in mind:
- Keep the signature width under 600 pixels to ensure compatibility across email clients.
- Use web-safe fonts such as Arial, Verdana, or Helvetica.
- Host images externally (on your web server) rather than embedding them, to reduce email size and avoid rendering issues.
- Avoid overly complex layouts — many email clients strip advanced CSS.
Step 6: Save and Test
Click Save to apply your signature. Compose a new email to verify that the signature appears correctly. Send a test message to yourself and check how it renders on desktop, mobile, and in different email clients such as Outlook, Gmail, and Apple Mail.
Common Challenges With Roundcube Signatures
While setting up a single signature in Roundcube is straightforward, IT administrators managing teams quickly encounter significant limitations:
- No centralised management: Each user must configure their own signature manually. There is no admin panel to push signatures to all mailboxes at once.
- Inconsistent branding: When employees create their own signatures, formatting, logos, and information inevitably vary across the organisation.
- No dynamic content: Roundcube does not support dynamic fields that auto-populate with user-specific data such as name, department, or phone number.
- Maintenance burden: Every time your company updates its logo, adds a marketing banner, or changes legal disclaimer text, someone must manually update every single user's signature.
- Mobile and app gaps: Signatures configured in Roundcube only apply when sending from the Roundcube webmail interface. If users also access email through a mobile app or desktop client, the signature may not carry over.
The Solution: Centralised Signature Management
For organisations with more than a handful of employees, centralised email signature management eliminates these pain points entirely. Instead of relying on individual users, IT administrators can design, deploy, and update signatures from a single dashboard.
This is where a dedicated solution becomes invaluable. With centralised management, you can:
- Design one professional signature template for the entire company.
- Automatically populate user-specific fields (name, title, phone, department) from a directory or data source.
- Push updates to all users instantly — no manual intervention needed.
- Ensure every outgoing email carries a consistent, on-brand signature regardless of which device or client is used.
- Add marketing banners, event promotions, or seasonal campaigns across all signatures in seconds.
- Maintain GDPR-compliant legal disclaimers uniformly.

Practical Tips for Roundcube Signature Success
Whether you manage signatures manually or through a centralised tool, keep these final tips in mind:
- Keep it concise: A signature should be informative, not overwhelming. Aim for four to seven lines of text content.
- Optimise images: Compress logo files and use standard formats (PNG or JPG). Large images slow down email delivery and may be blocked by recipients' email clients.
- Include legal requirements: Many EU member states require business emails to include company registration numbers, VAT numbers, and registered office addresses.
- Test across clients: Always verify your signature in Outlook, Gmail, Apple Mail, and on mobile devices before rolling it out company-wide.
- Review regularly: Schedule a quarterly review of your email signatures to ensure all information, links, and branding elements are current.

Setting up a basic email signature in Roundcube is simple enough for any individual user. But for IT administrators managing teams at Belgian and European B2B companies — or hosting providers supporting multiple clients — the manual approach quickly becomes unsustainable.
