Which one is for you
Pick Exclaimer if
- Fits if your IT team runs Microsoft 365, Exchange or Google Workspace and wants signatures on every device
- Works for companies that need a legal disclaimer on every outgoing email
Look elsewhere if
- Not for you if you're one person or a tiny team, as licensing has a 10-user minimum
- Tight if you're on Starter, which allows one signature template for the whole company
- Pricey if you want engagement reports, HubSpot or Salesforce targeting or HR sync, which are Pro at $1.75 a user
- Skip it if you want a free plan, because there's only the 14-day trial
- Watch out: monthly billing is offered, but the pricing page only shows the yearly prices
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

Key features
Exclaimer
- Server-side and client-side signatures
- Every plan can add signatures on the mail server as messages leave, including from phones, or in Outlook and Gmail through an add-in so people see them while typing.
- Directory and HR sync
- Fills signatures from Entra ID or Google Directory; Pro also syncs from HR systems such as Workday, BambooHR and ADP Workforce Now, or a CSV.
- Banners and campaign scheduling
- Starter allows one banner; Standard and Pro rotate several and switch designs on a schedule for the length of a campaign.

- Use different signatures for internal and external mail, exclude users or groups, and on Pro target banners at HubSpot or Salesforce lists.
- Engagement dashboard
- Pro reports click-throughs on signatures and banners and can run A/B tests between designs.
- Disclaimers and brand kits
- Applies legal disclaimers to every email and keeps logos, colors and fonts in brand kits shared with meeting backgrounds.
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.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
