How many files could I sign with my license?

Hi Albert.olive,

I have checked your account with the email address that you used to login to the forums.

You are using the trial account for Adobe Sign.

The trial account for Adobe sign consists of all the features that are available in the Enterprise account except the integration.

There is no limit set to send the documents for signature in the trial account.

You can sign any number of documents sent to you.

There is no limit for signing the documents in any of the accounts.

If you purchase the Adobe Sign subscription, you will get the 150 transactions per year for the individual account or Team account of Adobe Sign.

To get more transaction per year, you will need to either go for Business or the Enterprise account.

For more details, I would suggest to contact the sales team here  Contact Us | Adobe Sign (formerly EchoSign) - Adobe Document Cloud

You may also refer to this help link Adobe Sign plans for individuals and businesses | Adobe Document Cloud to check the services available with the different Adobe Sign plans.

Hope the information helps.

Let us know if you have any question.
