Hi @Nathan CK !
If you are using an eSign Personal plan purchased through the Docusign website, unfortunately you cannot purchase additional envelopes, as there is a limit of only 5 envelopes per month (non-cumulative). However, if you have another plan purchased through our website (such as Standard or Business Pro), the limits are more flexible. I recommend that you visit the website https://ecom.docusign.com/plans-and-pricing/esignature and search for the question 'How many Envelopes can I send for signatures each month or year?' available in our FAQ. There you will find all the details about the limits of the eSignature plans.
Please, let me know if I was able to help you with this question. If so, could you please select click on the "Select as Best" option? Thank you!
