About

Signatoro is a web-based email signature generator designed for individuals, teams, and AI assistants. Users can build a professional HTML email signature in minutes using five layout options, a single accent colour, and optional photo or logo upload. Signatures can be pasted directly into Gmail, Outlook (classic and new), Apple Mail, Zoho Mail, iOS Mail, or any mail client that accepts pasted HTML. For companies, a single logo, accent colour, and font are set once by the owner and propagate automatically to every team member's signature. When the owner updates the brand, all team members receive their new signature by email. Team members are invited by email and retain control of their own name, title, phone, links, and photo. Signatoro exposes a REST API with per-user API keys, allowing AI agents, CRMs, n8n, Zapier, and Make to fetch a user's saved signature on every send and append it to outgoing messages without any mail-server-level configuration.

About

Signivo is email signature management for Google Workspace and Microsoft 365, built so that anyone can run it, whether in HR, marketing, sales, or IT. One person can run it for the whole company. Your Google Workspace or Microsoft 365 admin connects it once; after that, design and rollout need no IT knowledge. Upload your existing signature as HTML, start from a template, or build a branded signature in the no-code editor, then deploy it company-wide with a single click. Names, titles, and contact details sync straight from your directory and stay current. Tailor signatures by role, location, or team, and roll out campaign banners or legal disclaimers everywhere in one step. Banners can be scheduled or rotated, and in Outlook people can pick the right banner for each email. EU-hosted in Germany, Google CASA verified, Microsoft Verified Publisher, and minimal permissions that never read your email content. One plan, every feature: €1 per user per month or €10 per user per ye

Pros & Cons from Real Users

Pros

  • just solved the most stupid problem we faced. we couldn't make grok bot and claude use the same signature everyone was using because apparently they send via API and when that happens the sig that sits in the settings is not be in - had to be in the prompt and then it was getting lost all the time. now both of them just call the single API and we have the centralized control. just what we needed
  • I had a freelancer setting up automated email sending workflows and for personal email sending I use Grok Bot. Neither one of those could add my email signature I have on Google and we only found out after we sent a whole bunch of emails. What I needed is a simple way to make sure one email signature is added to all our communications. So Grok found Signatoro and it's amazing, it's added as a step to the workflows and Grok Bot uses it when it sends.
  • The flexible layouts allow you to tailor your signature perfectly to your brand's identity, whether you need a minimalist text block or a detailed layout with banners and logos.
  • It is very easy to use and in my case, I mange a luxury travel booking platform so enforcing brand guidelines is very important. I tried the service and all signatures rendered are identical and matches brand guidelines.
  • Easy to use – The interface is simple and user-friendly. Easy email signature creation – Generating and customizing email signatures is quick and convenient. Many font options – Provides a variety of fonts to choose from. Flexible layouts – Offers different layout options for a more personalized look

Cons

  • nothing much, haven't even ineracted with it myself, all setup was done via the MCP
  • More design options would be great, we're in a flower business, so we need really fancy signatures. But I'd rather go without fancy than without a signature
  • Access to premium dynamic fields—such as promotional banners, social media feeds, or interactive CTA buttons—is often locked behind a paid subscription.
  • Not really a con but in the next phase maybe include options that would allow us to choose based on look and feel like luxury, outgoing, hip, chic, etc.
  • Test emails can sometimes have a slight delay.
