Signatoro

Signatoro gives you one email signature for every email you send: from every mail app, on every device, and from every AI agent and tool that sends on your behalf. When Claude or another agent writes and sends email for you, it fetches your saved signature from Signatoro and adds it, always the latest version. Your CRM, sequencer and help desk read the same signature from the same API, so one edit reaches every sender. Connect Zoho Mail once and changes reach it by itself. For companies: the owner sets one brand and one compliance footnote, such as a confidentiality notice or a registered-office line, with templates for the US, UK, EU and Canada. Every member gets it, and so does every agent with its own mailbox: it joins the company like a colleague and gets a matching signature. Agents count as members of the flat-price plan. Without signing in, Claude can make a signature from your name and details (HTML and plain text), show the layouts, and give the install steps for Gmail, Outlook, Apple Mail and more than 25 other mail apps and help desks. Signed in, Claude can fetch and update your saved signature, and company owners can list, invite, update and remove their people and agents. Signatoro handles signature details and company members only. It never reads or stores your email.
