| What it's for | General design. An email signature is one thing you can design in it, one person at a time. | Signatoro is the agentic email signature platform: one signature for a company's people and its AI agents, and a free signature for a single person. |
| Signatures for AI agents | Canva designs a signature for one person, who exports and pastes it in by hand; an AI agent that sends email is set up separately. | AI assistants and company AI agents: each gets its own API key or MCP connection, and a key or connection bound to an agent is locked to it. An AI assistant or company agent signs as the person (their own signature, with an optional disclosure line) or as itself (the agent's name and role in the company brand, without a personal phone or photo). A company owner can require one AI disclosure line for every company agent and every member's AI assistant. |
| The company's legal footer | Any legal text is part of one person's design; there is no company footnote that reaches every person and every agent. | On the Up to 15 plan or larger, a Signatoro company writes one compliance footnote, such as a confidentiality notice or a registered-office line, that goes under every person's signature and every company AI agent's signature, starting from US, UK, EU, Canada, healthcare or finance wording; the Up to 50 plan also keeps a history of who changed the footnote, when, and what it said. |
| Switching AI agents | A Canva signature is pasted by hand into each mail app, so each new AI agent is set up by hand too. | Signatoro keeps a company's signature when it switches AI agents or providers: the signature is saved on Signatoro, not inside any one agent, so a new agent connected over MCP or the API sends the same signature from its first email, and an edit on Signatoro reaches every agent's next email. |
| The company's brand | Canva designs a signature for one person; there is no plan that gives a company one shared, managed footer. | A shared company footer - logo, layout, color, font, review badge and booking button - that every member's signature follows. |
| Getting it into your mail app | Exported from Canva and pasted in by that one person. | Gmail: installs by copy-paste, no add-in, no IT. Outlook: installs by copy-paste, no add-in, no IT. Apple Mail: installs by copy-paste, no add-in, no IT. |
| A one-click option | None. Every mail app is a manual export and paste. | Zoho Mail: one-click install that updates itself. |
