# Newoldstamp Alternative: Signatoro

Newoldstamp centrally manages and updates email signatures for a company, billed per signature a month, and its own FAQ states a signature stops working once the subscription lapses. Signatoro is the agentic email signature platform: one signature for a company's people and its AI agents, with each agent identified the way the company decides and, on the Up to 15 plan or larger, the company's legal footer on every one. Here is how the two compare, checked on 14 October 2026.

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. Newoldstamp is a centrally managed email signature platform billed per signature a month, with banner campaigns and analytics built in, and its own FAQ states a signature stops working once the subscription lapses.

**Choose Signatoro** a company's people and several AI agents send its email, it may add or switch agents, and it wants one signature and each agent identified the way it decides on every one of those emails, with its legal footer on the Up to 15 plan or larger, for a company of up to 50 people at a price set by its size rather than per signature.

**Choose Newoldstamp** a company wants banner campaigns and click analytics run from a central dashboard, and is comfortable paying per signature each month for that.

## Signatoro and Newoldstamp at a glance

**Signatoro:** Signatoro is the agentic email signature platform: save your signature once, and your people and every AI agent you connect use the same one. Each person's signature goes into Gmail, Outlook or Apple Mail with a guide for each mail app, or into Zoho Mail in one click, and each AI agent, from Claude and ChatGPT to n8n and the company's own code, connects to Signatoro over MCP or the API. 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 is free for one person and charges a company one flat monthly price set by its size; AI agents come on top and use no seat.

**Newoldstamp** (a centrally managed email signature platform billed per signature a month, with banner campaigns and analytics built in, trusted by over 8,000 businesses by its own count): Newoldstamp is a centrally managed email signature platform, trusted by over 8,000 businesses according to its own pricing page (read 20 September 2026). It charges $109 a year at its default plan size of five signatures, billed annually, on a slider that runs from one signature to 200 or more, with a 7-day free trial offered first; Newoldstamp's own calculator labels this about $1.8 per signature a month, a rounded figure that does not multiply out to $109 exactly (its true per-signature rate is closer to $1.82). Its own FAQ states plainly that a signature "will stop working as soon as your subscription expires or when you delete your account." Newoldstamp's Key Features list includes signature banner campaigns and in-depth analytics alongside Google Workspace and Office 365 integration.

## Side by side

|  | Signatoro | Newoldstamp |
| --- | --- | --- |
| 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. | Newoldstamp's own pages, read 14 October 2026, describe signatures for employees managed from a central dashboard, 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. | Newoldstamp's email signature management page describes adding and controlling a standard or custom legal disclaimer in each employee's signature; Newoldstamp's own pages, read 14 October 2026, describe no MCP server, API or other connection that an AI agent could fetch the signature or its disclaimer from. |
| 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. | Newoldstamp manages each employee's signature centrally, with Google Workspace and Office 365 integration; Newoldstamp's own pages, read 14 October 2026, describe no connection for AI agents that a switch would carry across. |
| 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. | Newoldstamp centrally manages and updates employee signatures from an admin dashboard, with Google Workspace and Office 365 integration (Newoldstamp's own site, read 20 September 2026). |
| 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. | Newoldstamp's own FAQ states plainly: "Your email signature will remain functional as long as your subscription is valid. But it will stop working as soon as your subscription expires or when you delete your account." |
| What does it cost? | 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. | Newoldstamp charges $109 a year, billed annually, at its default size of five signatures, on a slider that runs from one signature up to 200 or more. |
| Is the price per person, or one number for the company? | Signatoro's price is set by the company's size, and each extra member costs $1.50 a month. | Per signature. Newoldstamp's own pricing calculator bills by the number of signatures on the slider, so the total changes as a company adds or removes people. |
| Does it run banner campaigns and analytics? | Signatoro builds and hosts the signature itself; it does not run banner campaigns or track clicks on them. | Both are Key Features on Newoldstamp's own pricing page: signature banner campaigns and in-depth analytics, alongside the central management dashboard. |
| Is there a free trial, or does the free version stay free? | Signatoro's free version for one person never expires and is never billed; there is no trial period and nothing to cancel before one ends. | Newoldstamp offers a 7-day free trial before billing starts, according to its own pricing page. |

## When to choose Signatoro instead of Newoldstamp

### Signatoro for a company's AI agents

Newoldstamp's own pages, read 14 October 2026, describe centrally managed signatures, banner campaigns and analytics for employees, and no connection, signature or AI disclosure line for an AI agent. 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.

### Nothing routes through Signatoro

Newoldstamp centrally manages and updates signatures from an admin dashboard, and its own FAQ states a signature "will stop working as soon as your subscription expires or when you delete your account" (Newoldstamp's own FAQ, read 20 September 2026). Signatoro takes the opposite structure: a person pastes their finished signature from Signatoro into their own mail app once, and Signatoro never sees that mail again. Newoldstamp's central management depends on Newoldstamp's own systems staying connected and paid for; a signature already pasted into a mail app depends on nothing Signatoro operates.

### The per-signature bill, in a reviewer's own words

A four-star Capterra reviewer of Newoldstamp put the pricing shape plainly: "The main problem I have with this SaaS is the cost - the monthly per user model is very ticky tack. You wind up paying the same per month for an email signature as you do for a G Suite personal account" (Capterra, read 20 September 2026). Newoldstamp bills $109 a year at its default size of five signatures, and that per-signature meter runs regardless of company size. Signatoro's Company price is set by size: $9 a month covers up to 5 people, and each extra member adds $1.50 a month.

## When to choose Newoldstamp instead of Signatoro

### Signature banner campaigns with central analytics

A marketing or comms team that wants to run signature banner campaigns and read click analytics from one central dashboard is who Newoldstamp's own Key Features are built for; a customer testimonial on Newoldstamp's site describes changing "branded banners and event details centrally" with analytics "very powerful" (Newoldstamp's own site, read 20 September 2026). What that costs is Newoldstamp's own shape: a per-signature bill that runs as long as the subscription does. Signatoro has no banner campaigns and no click analytics.

### A dashboard that updates everyone's signature centrally

A company that wants one admin to update every employee's signature from a dashboard, without each person editing their own, is who Newoldstamp's Central Management technology is built for. What that costs is the same per-signature meter as everywhere else on Newoldstamp's pricing page: the bill scales with how many signatures the dashboard manages. On Signatoro, an owner sets the brand and each person's details once, and every change arrives in that person's inbox as a new signature to paste.

## Questions about Signatoro and Newoldstamp

### Can an AI agent have its own email signature in Newoldstamp or Signatoro?

Newoldstamp's own pages, read 14 October 2026, describe no separate signature or AI disclosure line for an AI agent. 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.

### Does Newoldstamp or Signatoro put the legal disclaimer on email an AI agent sends?

Newoldstamp adds a legal disclaimer to each employee's signature, and Newoldstamp's own pages, read 14 October 2026, describe no MCP server or API for an AI agent to fetch the signature from. 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.

### Which keeps the email signature when a company switches AI agents, Newoldstamp or Signatoro?

Newoldstamp's own pages, read 14 October 2026, describe no connection for 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.

### What does Newoldstamp cost for a small company?

Newoldstamp charges $109 a year, billed annually, at its default size of five signatures, on a slider that runs from one signature up to 200 or more (Newoldstamp's own pricing page, read 20 September 2026). Signatoro's Company plan, by comparison, is a flat $9 a month for up to 5 people.

### What does Signatoro cost for a small company?

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.

### What happens to a Newoldstamp signature if the company stops paying?

Newoldstamp's own FAQ states a signature "will stop working as soon as your subscription expires or when you delete your account" (read 20 September 2026). Signatoro applies no signature itself; it only generates what a person already pasted into their own mail app, so nothing already pasted breaks if a company stops paying Signatoro.

### How does Newoldstamp get the signature onto everyone's mail?

Newoldstamp centrally manages and updates employee signatures from an admin dashboard, with Google Workspace and Office 365 integration. 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.

### Is there a free trial?

Newoldstamp offers a 7-day free trial before billing starts (Newoldstamp's own pricing page, read 20 September 2026). Signatoro's free version for one person never expires and is never billed; there is no trial period.

### Should a company switch from Newoldstamp to Signatoro, or run both?

A company that wants signature banner campaigns and central analytics run from a dashboard has a real reason to keep Newoldstamp, and Signatoro does not run campaigns or analytics at all. A company whose people and several AI agents send its email, and that wants one signature and each agent identified the way it decides across all of them, with its legal footer on the Up to 15 plan or larger, has a real reason to move to Signatoro, as does a company tired of a per-signature bill or of a signature that stops working if the subscription lapses. The two are not built to run side by side on the same mailboxes, since both would be adding a signature to the same mail.

### How is Newoldstamp rated by its own customers?

Newoldstamp's own pricing page states a 4.6 out of 5 score across 587 reviews (read 20 September 2026); Capterra separately shows the same 4.6 rating across 584 reviews, with ease-of-use and customer-service both at 4.6 (capterra.com, read the same day). Signatoro has no independent review base yet to compare.

## Sources

Newoldstamp's pricing ($109 a year at the default five-signature size, billed annually, labeled by Newoldstamp's own calculator as about $1.8 per signature a month, a rounded figure: $1.8 x 5 x 12 is $108, a dollar short of the $109 Newoldstamp displays, so the true per-signature rate is closer to $1.82; a slider from one signature to 200 or more, a 7-day free trial), its "over 8,000 businesses" claim, its Key Features (central management, signature banner campaigns, in-depth analytics, Google Workspace and Office 365 integration), and its 4.6-of-5, 587-review score are all from newoldstamp.com/pricing/, read 20 September 2026. Its FAQ on cancellation ("Your email signature will remain functional as long as your subscription is valid. But it will stop working as soon as your subscription expires or when you delete your account") and on central management are from the same page's expanded FAQ accordion, read the same day. The banner-and-analytics customer testimonial (Anthony Cotter, Creative Director at Workvivo) is quoted from the same page. Capterra's 4.6 rating across 584 reviews, with ease-of-use and customer-service both at 4.6, and the "ticky tack" per-user cost quote (a four-star reviewer, Dave S., Owner) are from capterra.com/p/150779/Email-signatures/reviews/, read the same day. A separate Capterra review claimed "the minimum package is for five users," which could not be reconciled with the pricing page's current "min 1" slider label read the same day; that claim is not used, since the two sources disagree and the live page is the more current one. Signatoro's own facts and prices are Signatoro's, current as of the pricing live in apps/web/config/company-bands.config.ts, checked the same day. On 14 October 2026 the pricing page was re-read ($109 a year at five signatures, the "min 1" slider and the 7-day trial unchanged), and the AI-agent rows were read on newoldstamp.com (home, pricing, features and email-signature-management-software pages) and in its sitemap: the management page describes adding and controlling legal disclaimers, and none of those pages names AI agents, an MCP server or a signature API.
