Using WiseStamp and looking to replace it? Whether the reason is data residency, tiered costs or the weight of a multi-brand platform, this guide compares the options actually available — not just ATOM — and walks through the migration step by step, without changing your email routing.
Why organizations leave WiseStamp
- Data residency. WiseStamp runs on AWS, Azure and Google Cloud and offers a dedicated environment in the European Union; its security page mentions no Canadian region.
- 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.
- Tiered cost. A fixed monthly amount per tier ($19, $49 or $189), plus $1 per employee, with a currency the pricing page does not state, complicates budgeting in Canadian dollars.
- Features reserved for higher tiers. Server-side deployment, single sign-on and roles sit on the Platform tier; the audit log, on the Enterprise tier.
- Unused features. Multi-brand, campaigns and analytics add cost for an organization that just wants a reliable, compliant signature.
Alternatives to WiseStamp
Leaving WiseStamp 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.
- 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.
- Terminus. Email signature marketing (Sigstr) built into an account-based marketing (ABM) platform, with banners that are dynamic by sender, recipient and lifecycle stage; Terminus merged into DemandScience in November 2024 and its signature product pages now redirect to DemandScience's site, with no public price. Suits a B2B marketing team that mainly wants an advertising channel in its employees' emails; confirm with the vendor that the offer is still sold on its own. See ATOM vs Terminus.
- 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 WiseStamp to ATOM, step by step
- Take stock of your signature templates and their targeting rules in WiseStamp (tiers, groups, deployment modes in use).
- 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 WiseStamp'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 WiseStamp at cutover: uninstall its Outlook add-in and, if you were using its server-side mode, delete the mail flow configuration it required in Exchange Online, per WiseStamp's documentation, to avoid duplicate signatures.
- Check the rendering on a few accounts (web, desktop, mobile) before cancelling WiseStamp.
What you lose by leaving WiseStamp
In all honesty, WiseStamp offers real features that ATOM does not have:
- Server-side and hybrid deployment, which adds the signature without relying on an installed add-in.
- Gmail and Google Workspace support, if your organization is not exclusively on Microsoft 365.
- Management of several organizations (multi-brand) in a single account.
- Published certifications (SOC 2 Type II, ISO 27001, ISO 27018), which ATOM does not claim.
For an organization that really uses these features, leaving WiseStamp means replacing them with another tool, or doing without.

Frequently asked questions
Can I bring my WiseStamp templates over to ATOM?
Yes. The ATOM visual editor offers "Import HTML": paste your WiseStamp 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 WiseStamp before installing ATOM?
No, you can deploy the ATOM add-in while WiseStamp is still active to test the rendering. At cutover, however, remove WiseStamp (the Outlook add-in and, if you were using its server-side mode, the mail flow configuration it required) to avoid two signatures being added to the same message.
How long does switching from WiseStamp 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 WiseStamp 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), Rocketseed (managed server-side deployment), Opensense (email tracking and integrations), or Microsoft 365's native signature for a minimal, static need.
Replace WiseStamp 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.
