Many extensions are available from companies you already use for domain registration — such as Hover. This is achieved by using a redirect which links to the web page that has a long URL.
Generally, read receipts are only useful within an organization where all employees/members are using the same email service and application. Some shortening services, such as goo.gl, tinyurl.com, and bit.ly can generate URLs that are human-readable, although the resulting strings are longer than those generated by a length-optimized service. How are you tracking calls from pay per click and organic?
Such URLs are difficult to memorize, type-out or distribute.
When this feature is used, links to your site that Sailthru includes in your email campaigns are wrapped in a redirect URL beginning with link.
They can hide their nefarious links in a shortened URL meaning people either clicked on the links and quickly learned to either never trust a shortened link, or to always use a link extraction site (e.g. WhereDoesThisLinkGo) to see where the shortened link actually went before they clicked. Given the choice between spending time and money to find a different home, or just giving up, the latter won out.[22] Google's url-shortener discussion group has frequently included messages from frustrated users reporting that specific shortened URLs have been disabled after they were reported as spam.[23] A study in May 2012 showed that 61% of URL shorteners had shut down (614 of 1002).[24] The most common cause cited was abuse by spammers.
Check Validation: Also optional, but this just makes sure the user “really” clicked on the link. Keys can be generated in base 36, assuming 26 letters and 10 numbers. It is where a link tracker tool comes in handy and will do the job that would take you forever to do. That limits your ability to do roll-up and drill-down reporting.
