ATOM Signatures

ATOM Signatures is an email signature management platform for Microsoft 365 and Outlook, built and hosted in Canada. IT admins design signatures once in a visual editor, target them by Microsoft 365 group, user or shared mailbox, and an event-based Outlook add-in applies them automatically on every new email, reply and forward. It works on Outlook for Windows, Mac, the web, the new Outlook, and Outlook mobile on iOS and Android. Employees have nothing to install or configure. Unlike server-side signature tools, ATOM inserts signatures client-side: your emails are never rerouted through a third-party server and never leave Microsoft 365. Employee details (name, title, phone) are read from your directory through Microsoft Graph with read-only access, so signatures stay up to date when someone changes roles or leaves. Configuration data is hosted 100% in Canada, which simplifies compliance with Quebec's Law 25 and PIPEDA. Key features: - Visual signature editor with dynamic fields and a separate reply/forward version - Targeting by Microsoft 365 group, user or shared mailbox - Banner editor, scheduled banner campaigns with up to 3 A/B variants, and cookieless click analytics - Native bilingual interface (English and French) - Multi-tenant console for MSPs and Microsoft 365 resellers Pricing is simple: CAD $1 per user per month, all features included, with discounted rates for nonprofits and the public sector. Shared mailboxes don't use a seat. 14-day free trial, no commitment.

Sigil

Sigil is an email signature management platform built specifically for Microsoft 365 organisations. Admins design and manage signature templates centrally — including drafts, versioning and rollback — and Sigil applies them automatically in Outlook as each user composes a message, personalised per person from Microsoft Graph directory data (name, job title, department, phone numbers, and more). What sets Sigil apart is visibility: most signature tools can tell you a signature was served, but not whether it actually applied. Sigil's per-mailbox adoption telemetry closes that gap, surfacing exactly which users have never successfully received a signature — so IT teams can fix silent failures before a client or colleague notices a missing signature first. Sigil also includes assignment rules (by department, office, domain or Entra group), time-boxed campaign banners, privacy-preserving link-click analytics, per-domain compliance footers, and role-based access for admins, editors and marketing users — all for one flat price per licensed mailbox, with shared and resource mailboxes free.
