The number of envelopes you can send for signature depends on your plan. 
eSignature Personal
Our eSignature Personal Plan includes 5 envelopes every month. Once an Envelope is sent, it will count toward this allowance whether or not the envelope is signed or completed. Should you need more than 5 envelopes per month, you can upgrade to an eSignature Standard or Business Pro plan.
eSignature Standard Unlimited and Business Pro Unlimited
With annual eSignature Standard Unlimited or Business Pro Unlimited plans, you can send as many as you want through our web app. No limits, no extra costs.
With monthly eSignature Standard or Business Pro plans, each user can send up to 10 envelopes per month. Once an envelope is sent, it will count toward this allowance, whether or not the envelope is signed or completed. The number of envelopes sent for signature using PowerForms or Bulk Send will also count toward this allowance. 
If your envelope usage exceeds your plan allowance, each excess envelope will be billed following a “Pay-As-You-Go” model, and you’ll be charged a set, per-envelope fee. This ensures you can continue using your Docusign eSignature service without interruption to your business. To increase your subscription allowance, you can pre-purchase envelopes on the Plans & Billing page of your account. This allows you to plan ahead and save costs as your business grows.
For the most current information on your envelope management options please see here. Docusign may occasionally run promotional envelope discounts that will be offered through email notifications. 
Enhanced plans
Enhanced plans can be customized to reflect your specific needs. As a result, envelope limits vary based on the terms of your plan. If you have questions, please contact our Sales team.
