I registered on SAMSON Connect but haven't received a confirmation email#

If you registered using a Gmail account then you might need to wait a bit since Gmail takes more time. You can access your SAMSON Key as well in your account on SAMSON Connect (see Where can I get my SAMSON Key?).

How can I get an academic status?#

The academic status allows adding some SAMSON Extensions for free and provides significant discounts (up to 90%) for many non-free SAMSON Extensions . To get an academic status please register with your institutional email address, we will provide you with an academic status in about 1-2 working days. If you registered with an academic email address and haven't received an academic status please contact us. Please note that if you modified your email address you will need to reinstall SAMSON with the new credentials.

If you don't have an academic email address but work in academia or you are a student please contact us.

Where can I get my SAMSON Key?#
