Step-by-Step Guide to Signing Email Attachments in Outlook Using DocuSign Add-in

For businesses relying on email for document exchange, the DocuSign add-in for Outlook simplifies the signing process. This feature enables users to prepare, send, and sign documents right from their email client, reducing manual steps and minimizing errors. Below, we’ll walk through the process in detail, assuming you’re using a recent version of Outlook (such as Outlook for Microsoft 365 or Outlook 2021) and have a valid DocuSign account.

Prerequisites for Using the DocuSign Add-in

Before diving in, ensure you meet these requirements to avoid interruptions:

• DocuSign Account: You need an active DocuSign eSignature subscription. Free trials are available, but paid plans (starting at $10/month for Personal) provide full access to envelope limits and features like templates and bulk send.

• Outlook Setup: The add-in works best with Outlook desktop or web versions connected to Microsoft 365. For mobile, limited functionality is available via the DocuSign app.

• Permissions: If you’re in a corporate environment, your IT admin must enable add-ins. DocuSign requires permissions to access attachments and send notifications.

• Document Format: Attachments should be in supported formats like PDF, Word, or Excel. DocuSign converts them into signable envelopes automatically.

Once set up, the add-in appears in the Outlook ribbon under the “Home” or “Message” tab, labeled “DocuSign.”

Installing the DocuSign Add-in in Outlook

Installation is straightforward and takes just a few minutes:

1. Open Outlook and Access Add-ins: Launch Outlook, go to the “Home” tab, and click “Get Add-ins” (or search for it in the search bar). Alternatively, in the web version, select “Apps” from the toolbar.

2. Search for DocuSign: In the add-in store, type “DocuSign” into the search field. Select the official “DocuSign for Outlook” add-in from the results.

3. Install and Sign In: Click “Add” to install. A pop-up will prompt you to sign in with your DocuSign credentials. Authorize the connection, granting Outlook permission to interact with your DocuSign account.

4. Verify Integration: After installation, restart Outlook if needed. The DocuSign icon should now appear in the compose or read pane when viewing emails with attachments.

This one-time setup integrates DocuSign’s API directly into Outlook, leveraging features like OAuth for secure authentication. Businesses often appreciate this for its scalability, especially in teams using Standard or Business Pro plans ($25–$40/user/month annually), which include collaboration tools.

Preparing and Signing an Email Attachment

Now, let’s focus on the core task: signing an attachment received via email.

1. Open the Email: Navigate to your inbox and open the email containing the attachment you need to sign. Ensure the attachment is downloadable—right-click if necessary to save it locally, though the add-in handles this in-place.

2. Access the DocuSign Add-in: In the email view, click the DocuSign icon in the ribbon (under “DocuSign” tab). Select “Sign a Document” or “Prepare a Document for Signature.” If the attachment is already embedded, the add-in will detect it automatically.

3. Upload or Select the Attachment: Choose the attachment from the email (e.g., a PDF contract). DocuSign creates an “envelope”—a secure container for the document. You can add multiple signers here, including yourself, by entering email addresses.

4. Place Signature Fields: Use the drag-and-drop interface to add signature, date, or text fields. For self-signing, position the signature field where required. DocuSign’s conditional logic (available in Business Pro) allows fields to appear based on previous inputs, ideal for dynamic contracts.

5. Review and Sign: Preview the document. Click “Sign” to apply your electronic signature—DocuSign uses a secure, encrypted method compliant with ESIGN and eIDAS standards. You’ll draw, type, or upload your signature.

6. Complete and Send: Once signed, save the envelope. If others need to sign, route it via email notifications. The add-in updates the original email thread with a signed copy attached. Track status in your DocuSign dashboard or Outlook sent items.

Troubleshooting Common Issues

• Add-in Not Visible: Check if it’s enabled in Outlook’s “Manage Add-ins” settings. Ensure your DocuSign plan isn’t expired—envelope limits (e.g., 5/month for Personal) can halt actions.

• Attachment Errors: Large files (>25MB) may fail; compress them first. For API-integrated setups (Advanced plans at $480/month), use webhooks for automated workflows.

• Compliance Check: Always verify signer identity if needed via add-ons like SMS delivery (per-message fee).

This process typically takes under 5 minutes per document, boosting productivity for sales, HR, and legal teams. In enterprise settings, DocuSign’s IAM (Identity and Access Management) features enhance security with SSO and audit trails, part of Enhanced plans customized for large organizations.

Exploring DocuSign’s Broader Ecosystem

DocuSign extends beyond add-ins with its Intelligent Agreement Management (IAM) platform, including Contract Lifecycle Management (CLM). IAM CLM automates the entire agreement process—from drafting to negotiation and renewal—using AI for risk analysis and clause extraction. It’s ideal for enterprises handling high-volume contracts, integrating with CRM tools like Salesforce. Pricing for IAM starts custom, often building on eSignature tiers, with add-ons for identity verification (metered) ensuring robust compliance.

Competitor Landscape: DocuSign vs. Alternatives

In the e-signature market, DocuSign leads with its mature ecosystem, but competitors offer varied strengths. From a business perspective, selection depends on factors like cost, regional compliance, and integration needs. Here’s a neutral overview of key players.

Adobe Sign: A Seamless Integration Option

Adobe Sign, part of Adobe Document Cloud, excels in creative and PDF-heavy workflows. It integrates natively with Microsoft apps, including Outlook, via a similar add-in for signing attachments. Features include mobile signing, workflow automation, and AI-powered form filling. Pricing starts at $10/user/month for individuals, scaling to enterprise plans with unlimited envelopes. It’s particularly strong for design firms but can feel bundled with Acrobat subscriptions, potentially increasing costs for non-PDF users.

eSignGlobal: Regional Focus with Global Reach

eSignGlobal positions itself as a compliant alternative, supporting electronic signatures in 100 mainstream countries worldwide. It holds a strong advantage in the Asia-Pacific (APAC) region, where e-signature regulations are fragmented, high-standard, and strictly regulated—often requiring ecosystem-integrated approaches rather than the framework-based ESIGN/eIDAS models common in the US and Europe. APAC demands deep hardware/API-level integrations with government-to-business (G2B) digital identities, raising technical barriers beyond simple email verification.

The platform’s Essential plan offers high value at $299/year (about $24.9/month, though promotional pricing can dip to $16.6/month equivalents in some markets), allowing up to 100 documents for signature, unlimited user seats, and verification via access codes—all on a compliant foundation. It seamlessly integrates with Hong Kong’s iAM Smart and Singapore’s Singpass, making it suitable for cross-border APAC operations without seat-based fees that inflate costs in large teams.

HelloSign (Now Dropbox Sign): Simplicity for SMBs

HelloSign, rebranded as Dropbox Sign, emphasizes user-friendly interfaces and Dropbox integration. Its Outlook add-in supports quick signing of attachments with templates and reminders. Free for up to 3 documents/month, paid plans start at $15/month for 20 signatures. It’s lightweight for small businesses but lacks advanced API depth compared to DocuSign.

Comparative Overview

This table highlights trade-offs: DocuSign offers robustness at a premium, while alternatives prioritize affordability or niche compliance.

Final Thoughts on eSignature Choices

As businesses evaluate tools for signing email attachments in Outlook, DocuSign’s add-in remains a reliable choice for seamless integration. For those seeking alternatives, eSignGlobal stands out as a regionally compliant option, particularly in APAC, with cost-effective plans that avoid per-seat charges.
