Frequently Asked Questions

Free license, as the name implies, can be registered at no cost. This license is meant for personal use and some of its features are limited.
Personal and Business licenses are paid licenses with no feature limits. Find the list of all features on our Pricing page or the License model page. You can decide to buy the license as a subscription or for a one-time fee.

While the Free license allows you to set up a maximum of two accounts in eM Client, it is possible to add an unlimited number of accounts with the Personal or Business license.

Free license can be activated on one device at a time.

The paid licenses also enable you to use eM Client for commercial purposes. Commercial use is any activity that helps you make a profit – the Free license therefore cannot be used in company settings or on personal computers for any kind of work or business correspondence.
The Personal license is intended for home use and for freelancers or sole proprietors.
Personal license cannot be used in companies, schools, non-profit organizations, governments, or any other institutions, even if you are just an employee. In these cases, a Business license is required.

Business and Personal license users also gain access to the dedicated VIP support system. The support options are fully described in the Support overview.

If you’re not sure about the type of license that you need, please get in touch with our sales department at [email protected]

In the eM Client application, go to menu > Help > License.

Click the ‘Activate’ button and insert your activation key (including the hyphens).

If there is no Activate button and this section already seems to include some License information it means there already is a license activated on this computer.
If it's the correct license, you don't need to do anything.

If you wish to activate a different license, simply click ‘Deactivate’ first to remove the current license. The same button will then be replaced by the ‘Activate’ option so you can proceed using the steps above.

To check if your eM Client is up to date, navigate to Menu > Check for updates.

eM Client, however, checks for updates automatically. Updates are pushed in waves to avoid overloading the server so not all users receive the update notice at the same time.

You can check what your current installed version of eM Client is in Menu > Help > About.

With a Personal or Business license subscription, you can always use the newest version of the program. The same is true for Free licenses.

By purchasing a one-time fee Personal or Business license, you get the latest officially released major version of eM Client, all the smaller updates related to that version, and all older versions.
If you decide to upgrade to a newer version of eM Client, you will need to renew your license.

If you purchase one-time fee license with Lifetime Upgrades, you will gain access to all present and future versions of eM Client. You can purchase Lifetime upgrades separately at any time.

The full model is described and explained here.

Don’t worry, a lost activation key is no problem.

Simply enter the email address used for the license registration here and we will send you your activation key immediately.

If you have problems receiving the key, please make sure that you entered your address correctly and also check your Spam folder.

If you’re worried that you cannot retrieve your key because eM Client is in offline mode, please be aware that most email providers in this day have a webmail option, where you can login and get your messages through your internet browser (for example Gmail addresses can be checked in your browser at mail.google.com, Hotmail, MSN, Outlook and other Microsoft accounts can be checked at outlook.live.com, etc.).

Basic eM Client licenses are meant to be used on one computer only, so if you have one eM Client license and are using eM Client on two or more computers, you will be asked to re-activate your eM Client license each time you switch between the computers.

However, we offer significant discounts on multi-license orders so you can purchase all the licenses you may potentially need in bulk. If you have any questions regarding the purchase or would like to talk about the pricing individually, please contact our sales department at [email protected].

Update: New licensing manager has been released for PRO license users and is available at http://licensemanager.emclient.com/

SilverLight is no longer needed for access to our License manager.

Chrome recently pulled their support of Silverlight and as a result, the only browser that you can use to access licensing.emclient.com is Internet Explorer. 

If you are using Windows 10, you can still access Internet Explorer - simply type Internet Explorer into search and launch it

If you previously activated a Free license, your key will not be automatically replaced if you purchase a Personal or Business license.

You need to deactivate the Free license and activate the paid license instead.

1.    Go to Menu > Help > License
2.    Click the ‘Deactivate’ button (the button will change and the program will be turned to offline mode momentarily)
3.    Click the ‘Activate’ button
4.    Insert your new license key and confirm

Microsoft has officially ended support for Windows XP on April 8, 2014.
Unfortunately, this means that the security protocols from the last service update are no longer up to the current standard.

So when you try to activate the license after the eM Client trial, you will encounter an error message instead, because the request sent from Windows XP, unfortunately, doesn't arrive at our licensing system.

A problem has occurred when contacting the licensing server:

The underlying connection was closed:  an unexpected error occurred on a send.

We have created a compatibility version for XP which allows the connection, but please be aware that this version will not be updated in the future.
Please send us a message to [email protected] if you are interested in this version.

To change any data concerning your registered/purchased eM Client license, please contact us at [email protected] and we'll arrange the desired changes.

After 30 days of using eM Client, you might encounter this message:

Demo expired

Your demo period has expired. Please obtain a valid eM Client license from http://www.emclient.com/purchase

You may access your offline data, but online synchronization and the sending of emails are disabled. Once a license is obtained, you will be able to use the product without limitations again.

This means you haven't activated a license within the period of the trial version.

If you already registered or bought a license, just take your Activation key and activate it in Menu > Help > License.

Otherwise please go register or purchase a license from our website. Please make sure to register the license to an email address that you have access to, as the license key will be sent there.

You can upgrade to eM Client 10 by going to Menu > Help > Check for Update or by downloading it directly from our website.

IMPORTANT: Pro users whose licenses are only valid for eM Client 9 and older need to buy a one-time upgrade to Version 10 first, or their program will be in offline mode until they upgrade their license or revert back to their previous version.

Pro users with Lifetime Upgrades don’t need to make any additional purchases to access paid features in eM Client 10.

After your 30-day trial of eM Client expires, you can either continue using eM Client on a Free License (with limited functionality) or purchase a license.

After purchasing a license, simply enter your Activation Key by going to Menu > Help > License.

eM Client uses external service for translations, so it has to pay for each translation made through its interface. For this reason, Free license users have limited access to this feature.

There are no limits for paid licenses.

If you have trouble connecting to the license server to activate your license, make sure to add https://licensing.emclient.com/ and https://licensemanager.emclient.com/ to exceptions in any security apps, VPNs or Proxies.

You can overview your licenses using our License manager and even remotely manage specific activations. Find out how to manage your licenses or assign centralized settings to your activations.

If you cannot find your License manager login credentials, you can reset them here.

Please keep in mind that the credentials are case-sensitive and do not contain any whitespace characters.

This means that your license is activated on the number of devices your license was purchased for. You need to ‘free’ up some seats to use the same license on new devices. Either deactivate the license on the older device (Menu > Help > License) or if you do not have access to it anymore, use our License manager to remotely deactivate the older activation.
