# Sending options

> Sender, signature, automatic lock, and public link visibility

## Custom sender

<Info>
  This feature is available starting from the [**Pro** plan](/billing/plans/index).
</Info>

By default, sharing emails are sent from the there.do address with your name.
You can customise the display name and the reply-to email address.

To configure a custom sender:

1. In the share view, open the **Sender** section.
2. Edit the display name and/or the reply-to address.
3. If you enter a new address, a verification code is sent to it — you must have
   access to that inbox to confirm.

<Tip>
  This option is particularly useful for teams who prefer to send from a shared
  address such as `project@firm.com`.
</Tip>

## Automatic signature

<Info>
  This feature is available starting from the [**Pro** plan](/billing/plans/index).
</Info>

A signature is automatically added to every sharing email. It includes your
organisation's logo.

To customise the content:

1. Open the **Signature** section in the share view.
2. Edit the text as needed.

The signature is saved automatically and reused for future shares.

<Tip>
  The logo shown in the signature is the one configured for your organisation.
  To change it, go to your organisation settings.
</Tip>

## Automatic lock

You can automatically lock the document a set number of days after it is sent.
Locking disables comments and any further edits to the document.

To enable locking:

1. In the share view, open the **Lock** section.
2. Set the number of days after sending.

<Warning>
  A locked document can never be unlocked, even by its creator. Check the delay
  before sending.
</Warning>

## Public link

By default, only invited recipients and members of your organisation can access
the document.

To make the document accessible to anyone with the link:

1. In the share view, scroll to the bottom.
2. Change the visibility to **Anyone with the link can view**.

Once this option is enabled:

* The **Copy link** button generates a shareable public link.
* The **Share on WhatsApp** button sends it directly via WhatsApp.
* People without a there.do account are counted as anonymous in
  [read tracking](/features/sharing/read-tracking). They cannot comment on the
  document.
