Signitic is a French email signature management platform, with a free plan for up to 19 users and a paid tier starting at €1 per user per month. ATOM Signatures is a Canadian platform, built for Microsoft 365 organizations that must navigate PIPEDA, Law 25 or other provincial privacy laws. This comparison puts the two products side by side, criterion by criterion: hosting, deployment architecture, price, currency and license minimum.
Comparison table: ATOM Signatures vs Signitic
Signitic leans on a low entry price, a free plan for very small teams and ISO 27001 certification on infrastructure hosted in Europe. For a Canadian organization, those choices come with a flip side: a 20-license minimum as soon as you outgrow the free plan, billing in euros, and no Canadian hosting region. Here are the criteria that matter, side by side.
| Criterion | ATOM Signatures | Signitic |
|---|---|---|
| Data hosting | 100% in Canada | 100% in Europe; no Canadian region published |
| Deployment architecture | Event-based Outlook add-in, one mechanism across every platform, no installation | Chrome extension (Gmail), web add-in (Microsoft 365), mobile apps; installed agent as fallback on incompatible Outlook versions |
| Email routed through a third-party server | Never — client-side insertion at compose time | Not publicly specified |
| Entry price | CAD $1 / user / month, from the first user, all included | Free ≤ 19 users (Signitic branding visible), then €1 / user / month |
| License minimum (paid plan) | None | 20 |
| Billing currency | Canadian dollar | Euro only |
| Marketing features (campaigns, segmentation, CRM) | No — focused on the signature | Yes, from the Standard tier |
| Languages | Native FR-CA and EN-CA, bilingual support | Multilingual, support based in France |
| Microsoft 365 group targeting | Yes | Yes |
| Platforms covered | Outlook Windows, web, Mac, mobile iOS/Android | Outlook (M365) Windows, web, Mac, mobile; also covers Gmail/Google Workspace and Zoho Mail |

Architecture and deployment
Signitic deploys differently depending on the mail platform: a Chrome extension for Gmail and Google Workspace, a web add-in for Outlook and Microsoft 365, and mobile apps for iOS and Android. For Outlook versions incompatible with its add-in, the company offers an agent installed on the workstation as a fallback. Signitic's public documentation does not specify whether email content passes through its servers to receive the signature.
ATOM Signatures uses a single mechanism across every Outlook platform: an event-based add-in (OnNewMessageCompose / OnMessageSend) that inserts the signature at compose time, with no installation on the workstation. Deployment is centralized from the Microsoft 365 admin center. Email never leaves Microsoft 365: its content is never routed through any third-party server, at any point.
To understand why this distinction matters beyond technical comfort, see our guide on architecture without routing.
Canadian data residency
Signitic advertises infrastructure that is "100% made and hosted in Europe," with a commitment that no data leaves the European Union — a solid claim for the European market, but one that covers no Canadian region. For a Canadian organization, that means your employees' personal information (names, emails, phone numbers inserted in the signature) is hosted overseas.
ATOM Signatures hosts 100% of its data in Canada. The legal framework that applies depends on your sector and province: PIPEDA covers the private sector federally, several provinces have their own law — Quebec's Law 25 is only one example, alongside PIPA in Alberta and British Columbia or health-specific laws such as PHIPA in Ontario — and some provinces, such as Nova Scotia with PIIDPA, require or favour local storage for the public sector. Under any of these frameworks, knowing your data stays in the country simplifies the assessment required before any transfer. See our guides on Canadian data hosting and email data sovereignty.

Pricing, currency and license minimum
Signitic bills in euros only. Its free plan covers up to 19 users, with a single signature template, a single campaign and Signitic branding visible on every send. Beyond that, the Standard plan, at €1 per user per month, requires a 20-license minimum: an organization of 19 employees can neither stay on the free plan with paid-tier features nor pay for just 19 licenses.
ATOM Signatures bills directly in Canadian dollars, at CAD $1 per user per month, all features included, with no tier and no imposed minimum. An organization of 5 employees pays for 5 licenses; an organization of 500 pays for 500 — never more, never a feature locked behind a higher tier. A 7-day free trial lets you test your real configuration before committing.

When to choose Signitic, when to choose ATOM
Choose Signitic if…
- You are a European team of 20 employees or more, the lowest possible price is the top priority, and Canadian data residency is not a constraint.
- A team of under 19 people is enough for you, with Signitic branding visible in the signature (free plan).
- You need to cover Gmail, Google Workspace or Zoho Mail alongside Microsoft 365 on a single platform.
Choose ATOM Signatures if…
- You are a Canadian organization subject to Law 25, PIPEDA or an equivalent provincial law, and want 100% Canadian hosting.
- You have fewer than 20 users and refuse to let a license minimum force you to pay more than necessary or display a third-party brand.
- You are exclusively on Microsoft 365 and want centralized deployment, with no installed agent as a fallback on any device.
- You prefer billing in Canadian dollars and a native bilingual FR-CA/EN-CA product.
