how do I get the trial version of adobe pro send?

Hi denisec6154180,

Adobe doesn't offer trial versions of the Acrobat.com online subscriptions. But, if you try it out and find that it's not what you are looking for, you can cancel within the first 30 days for a full refund.

We do offer 30-days trials of Acrobat, however, so maybe that's where you saw the free trial message. You can download the Acrobat Pro trial from http://www.adobe.com/products/acrobat.html.

Best,

Sara

Can you show a screenshot of what you saw online?  Someone else here might know what you are asking about but I have never heard of "adobe pro send".
