President

Being able to update signatures, contact info, license numbers, and disclaimers across the entire company from one dashboard saves real time and eliminates the inconsistency you get when employees manage their own signatures.

The integration with Microsoft 365 and Outlook was seamless, and the learning curve was very manageable, allowing us to quickly deploy professional, consistent signatures for all users.

Every email our team sends now includes a polished, uniform signature that reinforces our company’s professionalism, while the centralized management makes updates simple and secure without relying on individual users to maintain their own signatures.

IT Infrastructure Manager

The administration console is intuitive and flexible, allowing rule-based targeting by department, branch, or user group without reliance on client configuration.

Vice President of Marketing

I also love the ability to test my email signature designs to ensure they have been set up correctly. Once email signatures are designed, it is very easy to add and remove new users and to create different buckets of user groups.

Senior Project Manager

It "Wordifies" them and that conversion breaks the earlier signatures in a chain. If they can figure a work around to that formatting issue, then I would have 0 critiques.

Creative Technologist

It currently functions a minimal level but QOL features like renaming the attributes, reorganising them and general customisation is still limited.

Director of Human Resources

We have several office locations and several different signature lines, and this product made it simple to have that without the need to adjust manually.

Head Of Engineering

Signatures apply perfectly whether emails are sent from Outlook desktop, mobile, or web — something native Microsoft tools still can’t match with the same level of polish.

The setup was quick, and the cloud/server architecture completely solved our problem of managing signatures seamlessly across all devices.

IT Service Delivery Supervisor

We used to generate signatures manually with html and propagate them with Group Policies that didn't always work.

IT MANAGER

I don't think I'm exaggerating when I say that it's truly the right tool for email centralization for those, like me, who manage a large M365 structure at the admin level.

Marketing Coordinator

Purchasing a subscription was a headache and the full day response time in working with [sensitive content hidden] to resolve the issue was frustrating. But we like the program and are excited to implement it for the company I work for.

Server-side processing means signatures look right whether emails are sent from Outlook desktop, OWA, or a phone.

IT Administrator

By the end of the first day I had already set up custome email signatures for each department with their own unique image.

CodeTwo Email Signatures 365 has been an excellent solution for standardizing email signatures across our entire organization.

Digital PR

Sometimes, the Outlook Web Add-on doesn't load reliable - but I don't know if it's a problem of Microsoft 365 Outlook or the Add-on itself.

Overall, CodeTwo has proven to be a stable, enterprise-grade solution well suited for organizations with strong governance and branding requirements.

Leitung IT

With this solution all mails leaving our organisation do have the same layout which is easy to put together and also using the access management function is not complicated for us to add users to the rules so they can manage the everything without the support of the IT team.

IT and Systems Manager

The signature editor has a learning curve for complex designs, but overall it's a reliable and management-approved solution.  

Business Operations

Set up of out of office signatures and some of the finer details we were trying to have in the signature were hard to do.

IT Strategy and Operations

The ability to insert dynamic content such as user photos or marketing banners greatly enhances our external presentation.

IT Manager

The control you have over your signatures. Besides that our marketing department is able to manage it by therselves

I especially like the ability to set an expiration date for the signature.

We've deployed it internally and at clients and the server/client side signatures all work well.

Marketing and Brand Coordinator

Maybe an easier way to create rules for banners to not be implemented on replies and forwards.

IT Technician

I quickly ordered it, tested it for a few hours in my spare time, and now our company enjoys professional, consistent signatures, even from mobile devices.

Director Technology

The only thing that's a pain is the limitations of email in general - when we make SFP or email changes internally, it takes hours to fully propagate which isn't a CodeTwo problem, it's just what it is.

CodeTwo Email Signatures fills a gap in the Microsoft 365 product offering perfectly.

Marketing Advisor

doesnt have a view or configuration in mobile version, sometimes it takes time to load but overall satisfied.

IT-Consultant

I tried to find a downside, but the time saved on manual signature updates far outweighs the subscription cost.

Systems Administrator

Consistent branding for emails (logos, banners, disclaimers)

Operations and Finance Manager

You do need to think about some of the rules for applying the signatures if you have multiple email accounts with different signatures. But this is does allow for greater flexibility.

CodeTwo Email Signatures 365 is greate application, however a little bit expensive to comparitiv other applications.

It's GDPR compliant, costs scale down with users, so also good for big environments.

Marketing Manager

It is a simple solution to have uniform email signatures for our company.

Prepertual and subscription with international payments options makes the professional email management very easy!

Director of IT

We haven’t found anything we don’t like, we do wish the option to remove old Outlook signatures would not be retired.

You get enterprise features without breaking the bank (suitable for small businesses).

Simple to implement and we have custom email signatures at the bottom of every email, forward, and reply.

Practice Manager

The way it just works, whatever device I'm using, whatever version of Office, I get a signature on every email, every time.

CodeTwo was painless to get setup & integrate with our Microsoft Workspace.  

Client Support Specialist

I really wish there was a UNDO button available when working on signature designs.

Chief Information Technology Officer

Setup of advanced rules can be tricky, signatures route via cloud, and updates may not apply instantly.

Most importantly, editing the signature in HTML works as expected, without any automatic formatting changes.

It’s been a huge time-saver and keeps our communications looking polished and consistent.

A great integration into Microsoft 365 with a comprehensive user interface.

User-friendly design editor for professional-looking signatures

Great for marketing campaigns (promotional banners, announcements)

ICT Project Delivery

I think they could make their menus and options clearer. But part of this issue is because I don't need to go into the admin section very often because the tool just works once it's set up.
