Verify a Signer's Contact Route Before Sending an Agreement

Verify the intended signer and their contact route before sending an agreement. A correctly formatted email address can still belong to the wrong person, a shared mailbox, or an outdated contact. Delivery success proves that a system accepted a message; it does not prove that the right person received it or has authority to sign.

The practical workflow has three parts: identify the intended role, confirm the contact details through an appropriate trusted route, and choose the signing platform's authentication arrangement for the agreement's requirements. Keep these checks distinct so one does not silently stand in for another.

Start with the signing role

Identify who is expected to sign and in what capacity. The person who negotiated the document may not be the authorized signer. An assistant may coordinate the process without being the signing recipient.

Use the organization's established approval process to determine the role. The contract-approval workflow guide helps separate document approval from execution. A completed internal review does not automatically confirm every external recipient.

Record the intended signer in the agreement's working record before entering addresses into the signing tool. This gives the sender a stable reference and reduces the chance of selecting an autocomplete suggestion without checking it.

Questions about legal authority or signature requirements should go to the responsible legal or business owner. A contact-verification procedure supports that decision; it does not make the legal determination itself.

Confirm the address through an established route

Use contact details already established in the business relationship or confirmed through the organization's official channel. If the recipient supplies a new address, ask whether it is the address they intend to use for signing and whether it belongs to them individually or to a shared function.

Read the full address. Display names and familiar logos can conceal a different domain or a small spelling change. An autocomplete entry may preserve a former employee or a previous role long after the visible name seems familiar.

For a new relationship, use a verification approach appropriate to the sensitivity of the agreement. That may involve a known organization contact or another approved process. Do not send the confidential document merely to test whether someone replies.

Keep the confirmation concise: who confirmed the route, when, and for which signing role. Avoid collecting identity documents unless the approved process requires them.

Treat unexpected contact changes as a separate event

A request to send the agreement to a new address deserves its own check, especially if it arrives close to a deadline or alongside a change in payment instructions.

The FTC's phishing guidance recommends verifying unexpected requests through a known route rather than the links or contact details supplied in the questionable message. Apply that principle to a last-minute recipient change.

Do not rely on replying to the same thread if the concern is that the account or conversation may be compromised. Use an independently established contact method to confirm the change.

A legitimate change can still be urgent. The aim is to resolve it accurately, not to create delay for its own sake. Define who can approve the change and how the revised recipient is recorded.

Distinguish email access from signer authentication

A signing link delivered by email may demonstrate access to that mailbox under the platform's model. It does not necessarily provide a separate identity check.

Adobe's authentication documentation illustrates that methods differ in their account requirements and authentication factors. A method requiring a platform login is not automatically an additional independent factor beyond every other part of the workflow.

Choose authentication according to the agreement's established requirements and the recipient's ability to use it. Confirm availability in the actual account and plan rather than copying a feature name from another organization's configuration.

Do not send a password or access code in the same message as the signing link when your intended control depends on a separate channel. Follow the platform's documented method and your organization's approved process.

Handle shared mailboxes and delegation explicitly

A shared address can be useful for coordination, but it may not identify which person will act. If the agreement is intended for a named individual, establish how that person will be selected and authenticated.

Ask whether the platform allows delegation or forwarding and how those actions appear in the record. Do not assume that forwarding an invitation preserves the intended signer identity.

If the recipient requests delegation, use the supported process and obtain any required approval. Update the working record so staff do not continue chasing the original person while another signer has taken over.

A copied recipient, reviewer, approver, and signer may have different access and action rights. Check each role in the send screen. A correct address assigned to the wrong role is still a workflow error.

For sequential signing, verify when each invitation is released. A recipient who has not yet reached their turn may correctly have no invitation. Checking that state prevents staff from sending a separate duplicate request merely because someone says they have not received an email.

Preview the actual envelope before sending

Review the recipient list, order, authentication settings, document version, and field assignments together. A separate check of each item can miss interactions, such as signature fields assigned to an earlier draft's recipient.

The document-version control guide helps establish which file is the approved version. Recipient verification should not be performed against a document that later changes without review.

Inspect the invitation text as well. The signature-request email guide explains how to state the purpose and expected action. A clear invitation helps the recipient recognize a legitimate request without asking them to ignore normal caution.

For high-consequence workflows, use the organization's defined second-person review where required. The reviewer should check the actual prepared envelope, not merely the sender's statement that the details are correct.

Plan corrections without leaving two active requests

If an invitation goes to the wrong address, follow the platform and organization's incident and correction process. Do not assume deleting the notification from your own inbox revokes the recipient's access.

Determine whether the agreement can be corrected, must be voided, or needs a new request. Confirm the status of the old invitation before sending a replacement so two competing versions are not active unintentionally.

OWASP's authorization guidance reinforces the importance of enforcing access at the resource level. Operationally, the sender needs confidence that the platform's revoke or correction action actually changes access as documented.

Notify the appropriate internal owner when information may have reached an unintended recipient. Keep the factual record of what was sent and what action was taken.

Preserve evidence of the completed route

After signing, retain the agreement and the platform's relevant audit evidence through the approved records process. The electronic-signature audit-trail guide explains the distinction between the signed document and events about its handling.

Keep contact confirmation, recipient changes, and approvals where the agreement owner can find them. These operational notes should be factual and proportionate, not a collection of unnecessary personal data.

Review failed deliveries and recipient corrections periodically. Repeated mistakes from autocomplete, shared addresses, or stale contact records suggest a process improvement rather than simply a need to remind senders to be careful.

A reliable signing route begins before the invitation leaves. It connects a defined role, a confirmed contact method, appropriate authentication, and a controlled correction process so the final record reflects the agreement the organization intended to send.
