Opensense vs WiseStamp (2026): which should you pick?

Pick Opensense if

• Fits if you're a large organization that wants IT-controlled signatures on Microsoft 365, Google Workspace or Exchange
• Works for US government contractors on Microsoft's GCC High cloud

Look elsewhere if

• Not for you if you're a small company: every plan has a $500 monthly minimum
• Watch out: every plan also needs a service plan whose price isn't on the pricing page
• Skip it if you want to try it without a sales call, as trials go only to accounts qualified through a demo
• Pricey if you want email tracking too, which is a separate line of plans from $20 to $65 a user a month
• Watch out: GCC High costs $2 more a user a month, and account and deal-stage targeting need Complete at $5

Pick WiseStamp if

• Fits if you want one signature on personal Gmail or Outlook.com and don't mind a WiseStamp line under it
• Works for small teams on Google Workspace or Microsoft 365 that want new hires' signatures installed for them

Look elsewhere if

• Tight if you're staying free, as the free signature only works on personal webmail and carries WiseStamp branding
• Pricey if you want banner campaigns and click tracking, which start on Grow at $49 a month plus $1 a person
• Pricey if you need signatures on phones with no setup: server-side signatures need Platform at $189 a month plus seats
• Watch out: Basic, Grow and Platform have a 3-seat minimum, and the prices shown are billed yearly
• Watch out: the pricing page's FAQ says there's no free version, while the help centre describes the Free plan in detail

Opensense

• Every plan has a $500 monthly minimum, and Opensense says a small company is better served by a free generator.
• Plans also need a service plan whose price is not published on the pricing page.
• Email tracking is a separate line of plans from $20 to $65 per user a month, with the same $500 minimum.
• Trials are offered only to accounts Opensense qualifies, through a demo.

WiseStamp

• The Free plan works only with personal webmail, not a company domain, and adds a WiseStamp line under the signature.
• Basic, Grow and Platform charge a base fee plus $1 per employee a month, with a minimum of 3 seats; prices shown are billed annually.
• Server-side signatures, which apply on phones without any setup, need Platform at $189 a month plus seats.
• The pricing page's FAQ says there is no free version, while the help center describes the Free plan in detail.

Opensense

Central deployment

Signatures are pushed by transport rule, Outlook add-in or both, with in-client previews, and work in Outlook, Gmail and Apple Mail on desktop and mobile.

Recipient-level insights

Reports deliveries, impressions and clicks on banners per recipient and per employee.

Directory, HR and SSO

WiseStamp

Signature studio and AI designer

Build a signature in a drag-and-drop editor from templates, or have the AI designer draft one from a prompt or logo. The AI designer is not on the Free plan.

Directory sync and auto-install

Connects to Google Workspace or Microsoft Entra to add new hires, keep names and titles current and install signatures without each person doing it.

Client-side and server-side deployment

Signatures go out through the Chrome extension, an Outlook add-in or the desktop app, or from the server on Platform and Enterprise so they apply on every device.

Banner campaigns and analytics

From Grow, schedule clickable banners in staff signatures and track impressions and clicks. Branded short links carry UTM tags.

Surveys in the signature

Embed one-click NPS, CSAT or custom surveys in signatures and have AI Insights summarize the answers. Platform can import results from other survey tools.

Rules and disclaimers

Lock legal disclaimers by department or region and send a shorter signature on replies and forwards. Targeting rules start on Grow.
