Features

An AI assistant, a CRM or a sequencer fetches your saved signature at send time over MCP or the API, as HTML and text or a short version for cold outreach, with your saved contact details to use as written. Free includes 50 requests a month; Company is unlimited.

An assistant that sends email for you gets its own key or MCP connection and signs either as you, under your saved signature, or as itself, with its own name and role line. By default its signature carries a line saying it is an AI and whom it acts for. Free includes 1 AI assistant; each person on a Company plan gets 3 AI assistants, on top of the people the plan covers.

The owner sets up agents that send email for the company or for one person, each with the company brand and an AI disclosure line. Up to 5 includes 3, Up to 15 includes 10 and Up to 50 includes 25, on top of the people the plan covers.

Line, Mark, Portrait, Stack and Compact, in a sans or serif font. Upload a photo and it is cropped round; upload a logo and it sits on a white plate. Both are hosted for you, so they show without attachments.

If your accent color is hard to read on white or in dark mode, Signatoro suggests a nearby shade that reads well on both.

See the signature as designed, or roughly how Gmail on phones and Outlook darken it, before you paste it anywhere.

Add a static Trustpilot, Google Reviews or G2 rating badge, a Calendly or Cal.com booking button, or both, each linking straight to your reviews or your booking page.

Paste a formatted signature into Gmail or Outlook, take the HTML, or use the plain-text version for apps that strip formatting. The test email comes with the install steps for your mail app.

Sign up and the signature you built comes with you. Edit it any time and copy it again.

Gmail, Outlook, Apple Mail, Zoho, Fastmail, Proton Mail, HEY, Thunderbird and more, on desktop and phone, with a search on the docs page.

Connect Zoho Mail once from your signature page and the signature goes in. Every later change, yours or your company's, reaches Zoho Mail by itself.

The owner sets the brand, the company name and the website once. Everyone keeps their own name, title, phone and photo.

A brand change emails everyone with a saved signature their updated one to paste; editing one person emails just that person.

People confirm with one click from their email, and the roster shows who is on the current signature.

Every signature in the company carries your brand and only your brand.

Each invitation carries the person's finished signature and the install steps for their mail app.

A picture of the signature for LinkedIn, Slack and anywhere you need an image, and unlimited API requests for every member.

Move between the Up to 5, Up to 15 and Up to 50 plans whenever you need to; the difference is prorated. On Up to 5 and Up to 15, add people past the size for $1.50 a month each.

The owner writes one short footnote, such as a confidentiality notice or a registered-office line, and it goes under every member's signature and every company AI agent's signature. Turn it off and everyone gets their signature without it by email.

Start from US, UK, EU, Canada, healthcare or finance wording, with your company name already in, and fill in the bracketed parts.

Who changed the footnote, when, and what it said. It is recorded on every plan, so a company that moves up sees its full history.

Each assistant or agent signs with a line you pick: AI assistant to a person, AI agent for the company, or drafted with AI and reviewed by a person. With it comes a matching sentence the agent can put at the top of the email. On Company, the owner can set one line for every agent and every person's assistant.
