The Insightly URL is a unique web address that users can access to log in to Insightly. The last part of this address is always .insight.ly but you can change the first part to something your users will remember, like http://mycompany.insight.ly. You can use any name that hasn't already been reserved.
Your Insightly URL must contain only the characters A-Z or a-z, the numbers 0-9, or the hyphen character. No spaces are allowed and it must include at least 5 characters.
If you change your Insightly URL, be sure to share it with your users so they can continue to access Insightly.
