The best MSP add-on services in 2025: why email signature management is essential for growth

By Leonie van Aswegen| Marketing

In 2025, the MSP industry is more competitive than ever. Businesses expect more than just IT support – they want strategic services that enhance productivity, security, brand visibility, and customer experiences. To stay ahead, successful managed service providers are offering MSP add-on services that deliver extra value beyond traditional cybersecurity and cloud solutions. Forward-thinking MSPs are finding new ways to strengthen brand presence, boost marketing engagement, and streamline operations to meet evolving client needs.

One service is emerging as both impactful and easy to implement: email signature management.

Here’s why it deserves your attention and how it can position your MSP for growth.

What makes a great add-on service for MSPs?

Before diving into the specifics of email signature management, let’s consider what makes an add-on service a smart choice for MSPs. The best options:

• Solve a pain point: Services should address real challenges your clients face, whether it’s improving security or simplifying workflows.
• Provide recurring revenue: Subscription-based services ensure steady income for MSPs. According to Canalys, IT managed services revenue is expected to grow approximately 13% year-on-year in 2025, reaching US$595 billion globally.
• Are easy to implement: Avoid offerings that require complex integration or extensive training.
• Enhance client loyalty: Services that directly impact a client’s business success strengthen the MSP-client relationship.

Email signature management for Microsoft 365 and Google Workspace checks all these boxes, making it a standout offering for 2025 and beyond.

Email signature management as an add-on service for MSPs

While often overlooked, email signatures are a powerful business tool. They sit at the intersection of IT, marketing, and compliance, offering benefits across multiple fronts.

Here are 4 key reasons MSPs should prioritize email signature management as an add-on service:

1. Email signature management ensures streamlined brand consistency for your clients

For businesses, ensuring consistent email branding across all outgoing communication is a common struggle. Without centralized management, email signatures vary wildly between employees, leading to inconsistent brand representation.

With an email signature management solution, MSPs can:

• Ensure every employee’s signature aligns with the company’s branding guidelines.
• Automate updates with active directory synchronization, so changes to contact details are instantly applied organization-wide.
• Offer value to marketing teams by adding promotional banners to email signatures, turning every email into a brand touchpoint.

2. Email signature management enhances security and compliance for MSP clients

In 2025, regulatory compliance and cybersecurity concerns continue to dominate IT discussions. Email signatures play a surprisingly important role here:

• Add legal disclaimers required for confidentiality and copyright compliance.
• Choose email signature management software that meets international data protection standards, including ISO27001, GDPR, POPI and HIPAA.
• Reduce the risk of phishing attacks by ensuring professional, uniform email signatures, which make fraudulent emails easier to spot.

4.  Ease of deployment: how email signature management can save time for MSPs

Compared to other IT solutions, email signature management is easy to deploy and requires minimal ongoing support. Many platforms integrate directly with popular email services like Microsoft 365 and Google Workspace, simplifying implementation.

By offering this service, MSPs can:

• Minimize time spent on manual updates and troubleshooting.
• Free up resources for higher-value projects.
• Provide a high-impact solution without overwhelming their teams.

How email signature management stacks up against other add-on services

MSPs have a variety of add-on services and reseller programs to choose from, each with their own unique benefits. Below is a comparison of email signature management with other common services, focusing on technical, financial, and organizational factors.

1. Cybersecurity tools

• Technical considerations: Vital for protecting client systems, but their implementation can be complex. They often require advanced expertise, continuous monitoring, and frequent updates to stay ahead of evolving threats. These tools are indispensable but resource-intensive.
• Financial considerations: A high-demand service with strong revenue potential. However, the upfront costs for training staff and acquiring advanced tools can be substantial. Additionally, the competitive market may pressure MSPs to offer these services at lower margins.
• Organizational considerations: Essential but often reactive in nature. While they address critical pain points like threat prevention and compliance, they don’t directly contribute to a client’s growth strategy or day-to-day operations.

2. Cloud backup and disaster recovery

• Technical considerations: Relatively straightforward to implement but require careful planning to ensure data integrity and accessibility. They also demand ongoing testing and monitoring to guarantee reliability during emergencies.
• Financial considerations: Generate predictable recurring revenue but face commoditization in a crowded market. Differentiating your offering often requires bundling additional features or providing exceptional customer support.
• Organizational considerations: Crucial for business continuity but are rarely seen as proactive growth enablers by clients. Their value is most apparent during crises rather than in everyday operations.

3. Automation platforms

• Technical considerations: Streamline repetitive tasks, improving efficiency. However, they require significant customization to align with each client’s workflows and may involve a steep learning curve for MSP teams.
• Financial considerations: Can improve operational efficiency for clients, but their financial benefits are indirect – focused on cost savings rather than direct revenue generation.
• Organizational considerations: Improve efficiency by reducing manual workloads, which can enhance client satisfaction over time. However, they require significant effort upfront to customize workflows and demonstrate value.

4. Email signature management

• Technical considerations: Simple to deploy and integrates seamlessly with Microsoft 365 and Google Workspace. Active Directory synchronization ensures that updates are automated across all users, significantly saving IT team time and effort.
• Financial considerations: As a SaaS-based solution, it offers predictable monthly recurring revenue (MRR). It’s easy to bundle with existing services like Microsoft 365 licensing or IT support packages, creating additional value without significant overhead costs. Moreover, its marketing benefits can deliver measurable ROI for clients.
• Organizational considerations: Unique in its ability to impact multiple areas of a client’s business simultaneously – IT (streamlined operations), marketing (enhanced engagement), and compliance (consistent legal disclaimers). It directly supports growth by turning everyday company emails into branding opportunities while simplifying administrative tasks for IT teams and addressing visible pain points.

While all these services have merit, email signature management stands out for its low barrier to entry and high impact across multiple business functions. It provides a unique opportunity for MSPs to enhance their service offerings while delivering significant value to clients.

Marketing email signature management to clients: best practices for MSPs

When marketing this service to your clients, focus on:

• Time savings: Highlight how centralized management eliminates the hassle of manual updates.
• Marketing value: Show how email signatures can drive website traffic, event registrations, and direct sales, with engagement rates of up to 30%.
• Compliance and security: Emphasize the importance of consistent disclaimers and the role of professional signatures in preventing phishing attacks.
• Ease of use: Demonstrate how quickly the solution can be set up and maintained.

Why email signature management should be a core service for MSPs in 2025

In 2025, MSPs need to offer services that go beyond IT basics, providing measurable value to their clients’ operations, marketing, and compliance efforts. Email signature management is a hidden gem in the world of add-on services, combining ease of implementation with tangible benefits for clients.

By making email signature management a core part of your offering, you can:

• Strengthen client relationships through consistent branding.
