Available placeholders

For Signature field are available the following placeholders:

Placeholder name Description
{field_name:caption} this placeholder is used in order to retrieve the field's label
{field_name:signature} this placeholder is used in order to retrieve the signature image
{field_name:signature_image} Base64 encoded images are not accepted by Gmail, thus this placeholder will also retrieve the signature image and will ensure a proper functionality with all email clients.
{field_name:signature_url} this placeholder is used in order to retrieve the signature image URL when used within <img> tag, for example: <img src="{field_name:signature_url}" />

Note: You can use the above-mentioned placeholders in the Submissions front-end listings, Thank You message, Email messages and also in the PDF Attachment (the value field_name should be replaced with the actual name of the field).
