​@ayantik_biswas Thanks for your question.  If you are creating envelopes through the UI with a developer account, you should be unlimited.  You can check this using the Plan and Billing option under Admin.

If you are instead creating envelopes via API calls, check out the info in this article:

If you are still having issues with limits, you can create a case with Customer Support who can look at the specifics for your account: https://support.docusign.com/s/articles/How-do-I-contact-DocuSign-Customer-Support?language=en_US
