Check your email (including spam folder), you should get a mail with a redeem key.
You can redeem it here:
https://www.gog.com/redeem

Some users reported that the mail is buggy said:
"Redeem this code to add Tales from the Borderlands to your library. Act fast, it will expire on July 10, 21:59 UTC."

Do not worry, the key will expired in November instead of July.

Filtered by spam, already reedemed, thanks!!
