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 Signature Satori if

  • Fits if your company runs on Google Workspace
  • Works for teams that want signatures synced from Google Directory

Look elsewhere if

  • Skip it if you use Microsoft 365, as no sync is listed
  • Tight if you have under 5 users, since the subscription has a 5-user minimum
  • Watch out: six- and twelve-month subscriptions are arranged by contacting the vendor
  • Watch out: VAT is not included in displayed prices for European customers without a VAT ID
  • Skip it if you want a free plan, as there are only 5 credits on sign-up

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.

Engagement dashboard
Pro reports click-throughs on signatures and banners and can run A/B tests between designs.

Signature Satori

Imports users, organizational units and custom fields from Google Directory, and on the subscription refreshes them daily.

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.
