We have some good news to share: Letsignit has just renewed its ISO 27001 and ISO 27018 certifications, in their most recent versions, 2022 and 2025 respectively.
This renewal doesn't happen by chance. Since 2022, Letsignit has gone through uninterrupted audit cycles: each renewal involves a full reassessment of the controls in place, not a simple rollover. And maintaining certification against the latest versions of these standards, including ISO 27018:2025 published less than a year ago, means the requirements are never set in stone. Compliance is built, documented and questioned at every cycle.
Obtaining an ISO certification for the first time is already a substantial undertaking. Renewing it against updated versions of the standards is another matter entirely. Here's a quick reminder of what these two certifications represent:
Both certifications are awarded following an audit by an independent, accredited third party. For your teams, that's a documented guarantee, not a mere statement of intent.
Since 2018, Letsignit has made GDPR and data protection a structuring part of its organization. This renewal follows that same logic: a continuous, audited and documented approach, not a one-off effort.
To go further on our overall approach to data protection, Frédéric explains in detail what shapes our practices day to day.
Letsignit is directly connected to your employees' email systems. Every signature deployed handles personal data: names, job titles, contact details, photos. That's exactly what these certifications govern.
For IT and CISO teams, they provide a tangible element in any vendor qualification process. The 2022 and 2025 versions of the standards cover cloud and hybrid environments, directly applicable to a solution like Letsignit, and accredited third-party audits make the assessment objective, independent of any commercial claim.

For communications and marketing teams, it's the assurance that every email signature relies on infrastructure that is reliable, compliant and regularly audited. Our guide on email signatures and GDPR compliance explains how the two work together day to day.
Yes, with the 'Campaigns' offer, it is possible to track the number of clicks on the email signatures of all your employees in the 'Statistics' area of the platform.
You can then access a detailed or global view of the number of clicks on the email signatures of each employee. You can use the search option to target a specific signature or a given period. Finally, you have the possibility to export all statistics to an Excel document.
If you launch campaigns with banners inserted in your email signatures, you can also access their performance via this same space.
With Letsignit, you can easily add social network icons in your collaborators' email signatures and link to your company pages. Also, our "attributes" feature allows you to manage personalized URLs for each of your collaborators such as their individual LinkedIn profile.
And that's not all: you can add links to an appointment-setting application, allow your customers to leave reviews easily, and integrate our 'Chat on Teams' widget to let anyone start a discussion via Microsoft Teams chat.
It’s up to you! As an administrator of the Letsignit platform, you choose whether or not to grant modification rights to your employees. These permissions are managed on an attribute-by-attribute basis, which means that you can decide to allow the employee to change their phone number, but not the address of your premises, for example.
This feature applies to all attributes in your directory, including custom attributes created on Letsignit. When your employees change one or more attributes, your directory is obviously not affected.
It often happens that employees make their email signature their own: custom format, bad fonts, colors inconsistent with the brand standards... all of this has an impact on your brand!
A consistent visual identity is considered authentic and outperforms a perceived weak one by 20%. And, your customers are 2.4 times more likely to buy your products.
With Letsignit, take back control over your brand identity by standardizing all your email signatures. Our tool has many features that allow you to customize your signatures by department, by audience or by subsidiary. Not to mention the possibility of carrying out campaigns within your email signatures thanks to our Campaign offer.
What is the user experience like for our employees?
In both cases:
In short, they have autonomy in their email signature, but you keep control on the field, signatures, and banners they can edit or use.
With our "multi-signature" feature, your employees can benefit from multiple email signatures. No technical manipulation is required. Thanks to our Add-in for Outlook or the desktop app, they can change their email signatures as they wish with just a few clicks.
Regarding the creation of email signatures, you can make several variations such as:
Everything has been thought of to go further in the personalization process based on the recipient of your emails.
If sending emails has an impact, non-optimized email signatures also have an impact. An unsuitable format or an image that is too heavy considerably increases the size of your signatures... and therefore, your emails.
