Signatoro is the agentic email signature platform: a company saves its signature once, and its people and every AI agent it connects use the same one, with each agent identified the way the company decides and, on the Up to 15 plan or larger, the company's legal footer under every signature. WiseStamp is a centralized email signature platform that syncs from a company's identity provider and applies signatures through a client-side add-in or an optional server-side mode, built for marketing teams to manage company-wide without IT tickets.
| Signatoro | WiseStamp | |
|---|---|---|
| Can each AI agent sign as itself, with an AI disclosure line? | Signatoro lets a company decide how its AI agents identify themselves: an agent signs as the person it works for, by default with a line such as "Sent by Ada, my AI assistant", or as itself with its own name and role, and on Company the owner can require one disclosure line for every agent. A key or connection made for one agent always signs as that agent, so two agents with keys of their own each sign as themselves, even from one mailbox. | WiseStamp's own pages, read 14 October 2026, describe AI that designs a signature from a prompt or an image and AI that analyzes survey answers, and describe no separate signature, name or AI disclosure line for an AI agent. |
| Does the company's legal footer reach email its AI agents send? | 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. | WiseStamp's email disclaimer page describes a locked legal disclaimer that no employee can edit, which its server-side mode appends after an email leaves the sender's device, covering every email client; WiseStamp's pricing page lists server-side signing from the Platform tier, and WiseStamp's own pages, read 14 October 2026, do not mention AI agents in either place. |
| What happens when the company switches AI agents? | 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. | On WiseStamp's server-side mode, from the Platform tier, the signature is added to mail after it leaves a synced mailbox, whatever sent it, so a new agent sending from that mailbox gets the same signature; WiseStamp's own pages, read 14 October 2026, describe no connection of its own for an AI agent to fetch a signature. |
| How does the signature get onto everyone's mail? | Signatoro never sits in the mail path. Each person pastes their finished signature into their own mail app once; on Company it arrives in their invitation. The mail keeps going the way it already went, with nothing of Signatoro's in between. | WiseStamp applies signatures through a client-side add-in or browser extension, an optional server-side mode that signs mail after it is sent, or both together, synced daily from the company's own identity provider (WiseStamp's own site, read 30 September 2026). |
| Does the price grow with headcount, or stay flat? | Signatoro's price is set by the company's size, and each extra member costs $1.50 a month. | It grows. Every WiseStamp tier charges a base fee plus a fixed amount for every employee added, with no ceiling until the company moves to a higher tier. |
| What does it cost for a small team? | Signatoro is free for one person, with a small Signatoro link under the signature, and a flat monthly price for a company by size: $9 up to 5 people, $19 up to 15 and $49 up to 50, plus $1.50 a month for each extra member. | WiseStamp's Basic tier costs $19 a month plus $1 a month per employee, and its Pro+ tier for very small teams costs $9 a month plus $2 a month per team member for up to ten members, so a five-person team pays about $24 a month on Basic and a fifteen-person team pays $34 a month. |
| What happens if the company stops paying? | Signatoro applies no signature itself; it only generates the text and image a person already pasted in. So if a company stops paying, nothing already pasted into a mail app breaks, and the next signature built reverts to the free version with the small Signatoro link. | WiseStamp's directory sync and any server-side signing stop working as soon as the subscription that runs them lapses, since both depend on WiseStamp's own systems staying connected to the company's identity provider. |
| Does it run campaigns, surveys or click analytics? | Signatoro builds and hosts the signature itself; it does not run banner campaigns or track clicks on them. | WiseStamp's own site describes an Employee Hub, a Marketing Suite with click analytics, trackable links and native surveys, and an AI-assisted Signature Studio, aimed at letting marketing manage signatures without filing IT tickets; trackable links and surveys come with every tier, and campaigns, click analytics and the Employee Hub start on Grow. |
| Does mail from a CRM or another tool get the signature too? | Signatoro gives each AI assistant or company agent its own MCP connection or API key to fetch the saved signature before every email, signing as the person or as the agent with an AI disclosure line, and a CRM, a sequencer or the company's own code uses the same API, without routing that mail through Signatoro. | Yes, on WiseStamp's server-side or hybrid deployment mode, available on the Platform tier and above, because the signature is applied after mail is sent regardless of what sent it; on the client-side-only mode it depends on the sending tool using the same synced mail account. |

Signatoro's Company price is set by company size: $9 up to 5 people, $19 up to 15 and $49 up to 50, plus $1.50 a month for each extra member. Five people cost $9 a month and fifteen cost $19.
WiseStamp's server-side mode signs mail whatever sent it, and WiseStamp's own pages, read 14 October 2026, describe no signature or AI disclosure line of an agent's own. Signatoro is built for companies whose email comes from people and several AI agents at once: each agent connects over MCP or the API and fetches the saved signature when asked to sign, or on every email once its instructions say so, so a company that adds, replaces or switches agents keeps one consistent signature without pasting it anywhere again. Signatoro gives a company peace of mind about every email its people and connected agents send: the same brand everywhere, each agent identified the way the company decided, the person's real contact details, because connected agents are told to use only the saved values and never guess, and, on the Up to 15 plan or larger, the legal footer the company chose. A disclosure line or footnote states what the company chose to say; it does not by itself make an email compliant with any law. Signatoro's guide at signatoro.com/email-signature-compliance/ai-email-disclosure sets out what the US, UK and EU ask of email an AI sends.
WiseStamp can apply signatures two ways: a client-side add-in or extension that inserts the signature locally, or a server-side mode that signs mail after it leaves the sender, synced daily from the company's own identity provider. Signatoro takes neither path: a person pastes their finished signature from Signatoro into their own mail app once, and Signatoro never sees that mail again. WiseStamp's centralized modes depend on WiseStamp's own systems staying connected to the company's mail and its identity provider; a signature already pasted into a mail app depends on nothing Signatoro operates.
WiseStamp's Basic tier is $19 a month plus $1 a month for every employee added, with no ceiling until a company moves to a higher tier, so the bill climbs one dollar at a time as the company hires (WiseStamp's own pricing page, read 30 September 2026). A fifty-person company on Basic pays $69 a month before ever touching Grow or Platform's own per-employee add-on. Signatoro's price follows the company's size: extra members cost $1.50 each, so 30 people cost $41.50 a month and 50 cost $49.
WiseStamp's plans and prices are from wisestamp.com/pricing/, read 30 September 2026: Basic at $19 a month plus $1 per employee, Grow at $49 a month plus $1 per employee, Platform at $189 a month plus $1 per employee, Enterprise at a custom price, and Pro+ at $9 a month plus $2 per team member for up to 10 members, every tier billed annually; 1, 5 and 10 admins on Basic, Grow and Platform; trackable links and surveys on every tier, campaigns, analytics and the Employee Hub from Grow, and server-side signing from Platform. The five- and fifteen-employee totals are the pricing page calculator's own output, read the same day; the calculator raises any input below three employees to three, which is calculator behavior rather than a stated minimum. WiseStamp's deployment modes (client-side, server-side and hybrid), its daily sync from Microsoft Entra ID, Google Directory or a SCIM-compatible identity provider, its Employee Hub, Marketing Suite and Signature Studio, and the claim that most organizations deploy company-wide in under a day are from the wisestamp.com home page, read the same day. Prices were first read 20 September 2026 and were unchanged on 30 September 2026 and again on 14 October 2026; the feature tiers were corrected on 30 September 2026. The AI-agent rows were read on 14 October 2026: wisestamp.com/ai-capabilities/ (the AI Designer and AI Insights, which the page says covers what WiseStamp's AI can do today), wisestamp.com/email-disclaimer-management/ (locked disclaimers, appended server-side after an email leaves the sender's device), the home and integrations pages, and WiseStamp's page, post and guide sitemaps, none of which name AI agents, an MCP server or an agent API; where a WiseStamp page describes nothing for AI agents, this page says so and dates it rather than claiming WiseStamp cannot do it.
