How do I make a link work once?

8 replies
Hi All
I want to send out an email to customers with a link to a download page but I only want the link to work once or twice so the customer can't just pass the email on. Any ideas how?
Thanks

    Not possible within an email. All you can do is password protect the site the link sends them to or you can deactivate the site after a visit or two. However since I am presuming you are sending out multiple emails the only solution is to password protect the page linked to and track IP addresses so multiple people do not use the same passwword username combo.

  • Easiest way is to use php to write a cookie on the visitor's machine when they visit. Then you can know whether or not they have visited before and hide your page accordingly. Pretty simple to do for anyone who knows a little php.

    Then they click the link, it will be counted the hits
    and therefore block it after x numbers of tries.
    You need a unique id per link too.
    Or something...?

When someone visits your page the email in the link is compared to the database. If they've already been there then they don't get access.
    Kevin's solution will work, but you must implement it for the page and/or the link(s) you have in the page to download the product(s). So, if you have direct links to the product(s) without any kind of protection, users can easily share those links. But then, they can always share the downloaded product(s)

    ... complex with files and folders, either the file or the access protection would need to be changed dynamically by a script.

    but: what if the link would not point to the file ... but to an application that pulls it from a protected location ... ... ... ;-)

    i have developed a solution that does this.

    Each request is checked and validated. It works for images, movies and documents.

    it can be either required to log in, which tracks the visit aka download to the qualified user ... the link can be set to just expire after x calls .... or a certain date.

    .... better even: We do want the link to get passed around ... so when the next visitor comes around, the software automatically asks the visitor to qualify, either by opting in ... or paying.

    P.S. check out my channel on youtube.com/supersecretsoftware and look for "protected content videonote" ....

    In my previous answer, i supposed you would be interested in protecting the actual file that is offered for download, rather than just the page.

    Trained pirates are used to look up the source code or activity window to pass the direct link around. (... even most ´superstar marketers' do not protect their files well enough)

    The Amazon S3 has a protection system in place too, but a bit complex to handle.

    hope this helps
