Tool name: search-signatures
Lists the email signatures of a KlickTipp account that a newsletter can carry, with ID, name, the stored and effective sender address of their sender profile, the readiness of that identity, and the tags that make KlickTipp pick a signature by itself. A signature that cannot send using its own sender profile as it stands -- no content, missing legally required placeholders, or a sender address that may not be sent from -- is left out unless unusable signatures are asked for, in which case it comes with the reasons why. Each entry also says whether its digital business card carries data, which is what decides if add-email-editor-contact-card may select it. The signature text is not part of the list; use get-signature for that. To have KlickTipp pick the signature by tagging instead of naming one, pass signature ID 0 to configure-newsletter-delivery; that is not an entry of this list.
Text the name of a signature has to contain; omit to list them all
