About Signatoro
What Signatoro is, how it's different, and why it's named after a bull.
Signatoro is the agentic email signature platform: save your signature once, and your people and every AI agent you connect use the same one. Free for one person; a company pays by its size.
What Signatoro does
Signatures for AI agents and tools
An AI assistant, a CRM or a sequencer that sends mail on your behalf fetches your saved signature over MCP or the API at send time. An assistant can sign as you or as itself, with a line saying it is an AI.
A generator you fill in
Fill in your name, title and contact details, pick one of five layouts, and add a photo or a logo. It is free for one person, permanently, with a small Signatoro link under it.
One brand for the whole company
On the Company plan, an owner sets the logo, layout, accent color, font and review badge once, and a shared booking button if they want one. Everyone else keeps their own name, title, phone number and photo. Change the brand and every person gets an email with their new signature to paste.
What makes Signatoro different
One price for the whole team, by its size
Company costs $9 up to 5 people, $19 up to 15 and $49 up to 50, plus $1.50 a month for each extra member. The norm in this category is a price per person per month, usually with a five- or ten-person minimum.
Nothing runs on your mail server
Exclaimer, CodeTwo and Opensense route mail through a relay so they can stamp every message centrally. You paste your Signatoro signature into your own mail app, so if you ever stop paying, nothing already pasted breaks.
Paste and go
Building and installing a signature takes minutes: fill it in, copy it, paste it into your mail app.
An API for the tools that send your mail
A CRM, a sequencer or an assistant fetches your saved signature with one request, and every email it sends carries it.
Real text and real HTML
The signature is HTML and text: phone numbers stay selectable, links stay clickable, and a screen reader can read it. There's no tracking pixel and no per-recipient click tracking.
Who uses Signatoro
- Solo founders, freelancers and consultants who want a signature that looks considered, without hiring a designer.
- Small and mid-size teams, roughly 2 to 50 people, who want a flat price by team size.
- Teams and agencies whose CRM, sequencer or AI assistant sends mail on their behalf.
The meaning behind the name
Signatoro is Signature and Toro, the Spanish and Italian word for bull. Both halves are chosen on purpose.
Long before a signature meant a scrawl at the bottom of a page, a folded and sealed document was how you proved something was genuine. In old Japan, a certificate folded a specific way was called an origami; the idiom origami-tsuki, "with origami attached," still means certified today. In Europe, a stamped metal seal called a bulla did the same job, threaded through the folds of a letter so that tampering with it meant breaking the seal. That word is where "Papal Bull," and later "bulletin," come from.
Our bull is drawn folded, in that same flat, geometric style, on purpose, as a nod to the fold that used to mean a document could be trusted. Toro also carries a second, newer meaning: a bull market moves up with confidence, and that's the company we're building.
Put your name, and one certified mark, on every message a company sends, the same way, everywhere. We believe that brings a business good luck. That belief, more than a tagline, is what the name is carrying.
How it works
Open the generator and build your signature. No account is needed to try a layout. When you're happy with it, copy it, or copy it as HTML, and paste it into your mail app: the docs cover Gmail, Outlook, Apple Mail and iPhone Mail, step by step.
Running it as a company works the same way, plus one step: an owner sets the shared logo, layout, color, font and review badge (and a booking button, if the team shares one), invites the team by email, and each invitation arrives with that person's signature already built.
Questions go through the contact form. There's no phone line, and no published response-time promise.
