Frequently asked questions

1

Is it possible to track the number of clicks on email signatures?

Yes, 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.

2

Can we add links to social networks, our website, and appointment-setting applications such as Calendly?

With Letsignit, you can easily add social media icons, a vCard, and appointment links to your employees' email signatures. Our "attributes" feature also lets you manage personalized URLs for each team member, linking to their individual LinkedIn profile, for example.

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 conversation via Microsoft Teams chat.

3

Can employees update their signature information themselves (number, function, etc.)?

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 you can allow a team member to update their phone number, for instance, while keeping the office address locked.

This feature applies to all attributes in your directory, including custom attributes created in Letsignit. When employees update their information, your directory is not affected.

4

Why does consistent email signature management matter for your brand?

It's common for employees to personalize their own signatures, a non-standard font here, the wrong colors there. Over time, this kind of inconsistency chips away at your brand image.

A consistent visual identity is considered authentic and outperforms a perceived weak one by 20%. Customers are also 2.4× more likely to buy from a business they recognize. With Letsignit, you get complete control over every email signature across your organization, by department, region, subsidiary, or campaign, without overlooking the possibility of running email signature campaigns.

5

What is the user experience like for our employees?

  • If you opt for the Letsignit Add-in for Outlook, they will have a dedicated space in their Outlook account where they can view the signatures and campaigns assigned to them.
  • If you opt for the Letsignit Desktop App, they can preview all their signatures and campaigns from that space. If they want to switch their default signature before sending an email, they can do so directly from their signature library in Outlook.

In both cases:

  • They preview their signature before sending and choose from the ones assigned to them.
  • Based on the permissions granted, they can also update their personal information, name, job title, address, directly in the app.

In short, your team has autonomy over their email signatures, but you keep full control over the fields, designs, and banners they can edit or use.

6

Can my employees have multiple signatures available to them?

With our "multi-signature" feature, employees can access multiple email signatures with no technical setup required. Thanks to the Letsignit Add-in for Outlook or the Desktop App, switching between signatures takes just a few clicks.

You can create as many variations as you need:

Everything is designed to add a personal, relevant touch to every email, based on who's receiving it.

7

Regarding Green IT, have you implemented measures to limit the digital footprint of email signatures?

If sending emails has an environmental impact, poorly optimized email signatures do too. An unsuitable format or oversized image can significantly increase the weight of your signatures, and therefore your emails.

As a responsible software company, we contribute to reducing CO2 emissions in several ways:

  • Optimization of signature and campaign file sizes.
  • Green features: lighter signatures for reply/forward emails; option to avoid embedding images; lighter signatures for internal exchanges.
  • Integration of a 'Switch to Teams' widget to encourage employees to continue conversations via chat rather than email.
