Terminus (Sigstr) presents email signature marketing as one of the native channels of its account-based marketing (ABM) platform: banners that are dynamic by sender, recipient and lifecycle stage. ATOM Signatures takes the opposite angle — a dedicated tool that applies the right signature, hosted in Canada, with no email routing, at a single price in Canadian dollars. This comparison is for Canadian organizations on Microsoft 365: SMBs, professional firms, municipalities, public bodies, MSPs.
Comparison table: ATOM Signatures vs Terminus
Both solutions can manage Microsoft 365 signatures centrally, but they do not target the same need. Here are the differences that matter to a Canadian organization; criteria that Terminus does not publish are marked as such.
| Criterion | ATOM Signatures | Terminus |
|---|---|---|
| Nature of the offer | Tool dedicated to the email signature | One of the native channels of an account-based marketing (ABM) platform |
| Vendor status | ATOM Solutions, a Canadian company based in Quebec | Merged into DemandScience (announced November 12, 2024); the signature product pages redirect to DemandScience's site |
| Data hosting | 100% in Canada, by default | Not published on the pages consulted |
| Architecture | Client-side only (email never leaves Microsoft 365) | Not stated; Outlook integration mentioned |
| Price | CAD $1 / user / month, all-inclusive | No public price found; demo on request |
| Free trial | 14 days | Not stated |
| Banner campaigns, analytics | Yes — up to 3 A/B variants, click statistics | Yes — banners that are dynamic by sender, recipient and lifecycle stage |
| Targeting by Microsoft 365 groups | Yes — users, groups and shared mailboxes | Not stated |

What Terminus brings
Terminus builds its signature offer around account-based marketing:
- An advertising channel: each employee email becomes a targeted banner space, with analytics.
- Dynamic banners: the message changes by sender, recipient and lifecycle stage.
- A broader platform: account-based advertising, intent data, chat and web personalization, bundled with the signature.
This approach serves a B2B marketing team already equipped for account-based marketing. For an organization whose need is a reliable, compliant signature on Outlook, a full advertising platform adds cost and complexity with no matching benefit.
Where ATOM stands out for a Canadian organization
ATOM Signatures applies the right signature, reliably, to every person in a Canadian organization, banner campaigns and click statistics included. Against Terminus, four points make the difference:
- 100% Canadian hosting: configuration data and personal information stay in Canada.
- No email routing: the signature is inserted client-side, in Outlook, at compose time; email never leaves Microsoft 365.
- Native bilingual FR-CA / EN-CA: product, editor and support, useful across the country — including for federal and provincial bodies with bilingual obligations.
- Single, predictable price: CAD $1 per user per month, all features included, with no minimum, a 14-day free trial and a choice of monthly or annual billing (CAD $12/user/year).
ATOM Solutions is a Canadian company based in Quebec, and signature data is fed in real time by Microsoft Graph.
Price: on request or a flat CAD rate
The public Terminus pages consulted show no price for the signature offer: access goes through a demo. We therefore have no figure to compare, and we do not invent one.
ATOM Signatures applies a single flat rate: CAD $1 per user per month, all features included, with no tier or minimum, a 14-day free trial and a choice of monthly or annual billing (CAD $12 per user per year). See ATOM pricing.
The Terminus prices cited come from its public pages as of October 6, 2026 and may change; always confirm at the source.
Offer status, hosting and the Canadian legal framework
On November 12, 2024, DemandScience announced that Terminus had merged into it and that the combined company would operate under the DemandScience brand. As of October 6, 2026, Terminus's email signature software pages redirect to DemandScience's site, where we found no email signature offer. We could not confirm, on public pages, that the offer is still sold separately: ask the vendor before deciding. The hosting region and deployment architecture are not published on the pages consulted.
ATOM Signatures works exclusively client-side: an Outlook add-in inserts the signature at compose time. Email never leaves Microsoft 365 and is not routed through any third-party server, and configuration data is hosted in Canada. See our page on no-routing architecture and the guide to Law 25 and signatures.

When Terminus can fit
- Your B2B marketing team already uses an account-based marketing platform and wants to tie the signature into it.
- You mainly want an advertising channel in your employees' emails, more than a compliant signature.
- The vendor confirms that the signature offer is still sold and its hosting suits you.
Outside these cases, ATOM Signatures' Canadian hosting, client-side architecture and flat price better meet the needs of a Canadian organization. To broaden the comparison, see our analysis of the best signature solution in Canada and the ATOM vs Exclaimer comparison.
Frequently asked questions
Does Terminus still offer an email signature product?
We could not confirm it on public pages. DemandScience announced on November 12, 2024 that Terminus had merged into it; as of October 6, 2026, Terminus's signature pages redirect to DemandScience's site, where we found no email signature offer. Confirm the status of the offer with the vendor.
What does Terminus offer that ATOM does not?
Terminus builds the signature into an account-based marketing platform, with banners that are dynamic by sender, recipient and lifecycle stage, plus advertising, intent data and chat. ATOM Signatures offers none of these; it is a tool dedicated to the signature, which includes banner campaigns, up to 3 A/B variants and click statistics, at a flat rate of CAD $1 per user.
How much does Terminus cost compared to ATOM?
The public Terminus pages consulted show no price for the email signature; access goes through a demo. ATOM Signatures applies a single flat rate of CAD $1 per user per month, all features included, with no tier or minimum.
Can I switch from Terminus to ATOM without disruption?
Yes. Because ATOM works client-side through an Outlook add-in and is configured at the Microsoft 365 tenant level, you can deploy the add-in while Terminus is still active, recreate your templates in the visual editor, target by groups, then remove the old integration at cutover.
A compliant signature, hosted in Canada, at CAD $1 all included. ATOM Signatures automatically applies the right signature in Outlook, client-side, with 100% Canadian hosting and bilingual support.
