Using Terminus (Sigstr) for your signatures and looking to replace it? Whether the reason is the status of the offer after the merger with DemandScience, the lack of a public price or the need for a dedicated tool, this guide compares the options actually available — not just ATOM — and walks through the migration step by step.
Why consider leaving Terminus?
Because Terminus merged into DemandScience, its price and hosting region are not published, and the tool goes beyond what a simple signature needs:
- Offer status. Terminus merged into DemandScience in November 2024; its signature pages now redirect to DemandScience's site.
- Unpublished price. The pages consulted show no price: access goes through a demo.
- Data residency. The hosting region is not published on the pages consulted; it needs direct confirmation from the vendor.
- Legal framework. An organization subject to PIPEDA, or depending on the province to laws such as Law 25, PIPA or PHIPA, needs to know where personal information resides and where email is routed.
- A tool that is too broad. An account-based marketing platform adds cost and complexity for an organization that just wants a reliable, compliant signature.
Alternatives to Terminus
Leaving Terminus doesn't automatically mean choosing ATOM: here are the options, honestly, and who each one suits.
- ATOM Signatures. 100% Canadian hosting by default, strictly client-side architecture — email never leaves Microsoft 365 — and a single flat rate of CAD $1 per user per month, all-inclusive, banner campaigns included (up to 3 A/B variants, click statistics). Suits Canadian organizations for whom data residency and simple pricing outweigh CRM integrations. See ATOM pricing.
- CodeTwo. A vendor based in Poland, with a hybrid architecture (server-side relay on Azure, or client-side add-in) and advanced marketing features (banners, click tracking, satisfaction surveys), billed in tiers in US dollars with a ten-license minimum. Suits an organization that needs CSAT surveys or coverage for unmanaged devices, and for whom GDPR, rather than a Canadian framework, is the main reference. See ATOM vs CodeTwo.
- Exclaimer. A UK-based vendor with a broad marketing suite (banners, campaigns, CRM integrations), a 10-user minimum and tiered USD billing; a Canada hosting region exists but is not the default configuration. Fits an organization managing multiple international brands with complex CRM integrations. See the ATOM vs Exclaimer comparison.
- Letsignit. A French platform, hosted 100% in Europe, combining a client-side add-in with an optional server-side SMTP connector, plus digital business card (vCard) and governed PowerPoint presentation offerings. Suits an organization whose priority is a full marketing-campaign platform, with no constraint around Canadian residency. See ATOM vs Letsignit.
- Signitic. A French platform with a free plan for up to 19 users, then a paid tier starting at €1 per user per month with a 20-license minimum, hosted 100% in Europe, and which also covers Gmail, Google Workspace and Zoho Mail alongside Microsoft 365. Suits a small European team that prioritizes the lowest price or needs to cover several email platforms. See ATOM vs Signitic.
- WiseStamp. A New York-based platform deployable client-side (Outlook add-in, Chrome extension), server-side or hybrid, with an AI designer, banner campaigns and tiers (Basic, Grow, Platform, Enterprise) billed from $19 per month plus $1 per employee per month. Suits a multi-brand organization, or one also on Google Workspace, that values SOC 2 Type II and ISO 27001 certifications and for which Canadian hosting is not a requirement. See ATOM vs WiseStamp.
- Rocketseed. A vendor whose offer relies solely on server-side deployment (Microsoft 365, Google Workspace, Exchange), with no add-in to install, a public price grid starting at 50 employees, a one-time setup fee and 24/7 support with a dedicated account manager. Suits an organization of 50 employees or more that wants a turnkey setup and accepts that its outgoing email goes through the vendor's service. See ATOM vs Rocketseed.
- Opensense. A San Francisco platform deployable server-side, through an Outlook add-in or via the Gmail API, with banners, email tracking and integrations (directory, HR, CRM), priced from $1 to $5 per user per month with a $500 monthly minimum; data hosted in the United States by default, optional residency in Europe, Asia or Australia, SOC 2 Type II attestation. Suits a large organization that can absorb the monthly minimum, wants to link signature, email tracking and CRM, and for which US hosting is acceptable. See ATOM vs Opensense.
- Microsoft 365's native signature and Exchange transport rules. Free and already included in your subscription, via the local Outlook signature or an Exchange transport rule, but with unreliable images, no fine-grained group targeting, manual maintenance and no signature in Sent Items with transport rules. Suits a very small team with a single, static signature, no logo and no targeting. See ATOM vs Microsoft 365's native signature.
Switching from Terminus to ATOM, step by step
- Take stock of your signature templates, banners and their targeting rules in Terminus (Sigstr).
- Connect your Microsoft 365 tenant to ATOM Signatures: administrator consent, read-only access to the directory.
- Recreate your signatures in the ATOM editor with "Import HTML", then replace Terminus's dynamic fields with ATOM tokens (name, title, phone, etc.).
- Reproduce your targeting by Microsoft 365 groups, users and shared mailboxes.
- Deploy the ATOM add-in from the Microsoft 365 admin center, using the manifest URL generated in the Connections tab; allow up to 24 hours for propagation.
- Remove Terminus at cutover, following the documentation the vendor gives you: its public pages no longer detail the procedure, so confirm it with the vendor to avoid duplicate signatures.
- Check the rendering on a few accounts (web, desktop, mobile) before cancelling Terminus.
What do you lose by leaving Terminus?
In all honesty, Terminus offers real features that ATOM does not have:
- Dynamic banners by sender, recipient and lifecycle stage.
- An account-based marketing platform that bundles signature, advertising, intent data and web personalization.
For an organization that really uses these features, leaving Terminus means replacing them with another tool, or doing without.

Frequently asked questions
Can I bring my Terminus templates over to ATOM?
Yes. The ATOM visual editor offers "Import HTML": paste your Terminus (Sigstr) template's code, then replace its dynamic fields with ATOM tokens (name, title, phone, etc.) so the data updates automatically via Microsoft Graph.
Do I need to remove Terminus before installing ATOM?
No, you can deploy the ATOM add-in while Terminus is still active to test the rendering. At cutover, however, remove the Terminus integration following the documentation the vendor gives you, to avoid two signatures being added to the same message.
How long does switching from Terminus to ATOM take?
It depends on how many templates you have and how complex your targeting is. The only guaranteed timeframe is the add-in deployment itself: Microsoft states up to 24 hours of propagation for a new centralized deployment.
What other alternatives to Terminus exist?
Depending on your priorities: CodeTwo (advanced marketing features, GDPR), Exclaimer (marketing suite and CRM integrations), Letsignit (digital business cards and presentations, European hosting), Signitic (low price for a small European team), WiseStamp (tiers and AI designer), Rocketseed (managed server-side deployment), Opensense (email tracking and integrations), or Microsoft 365's native signature for a minimal, static need.
Replace Terminus without email routing. ATOM Signatures automatically applies the right signature in Outlook, client-side, with 100% Canadian hosting and a rate of CAD $1 per user.
