Part 01 · Overview

Welcome

What it is, who it suits, its grades and the ten things to know first

2.6

GPA, above 7 of the 9 other email signature tools we grade

Exclaimer manages email signatures for every mailbox in an organization from one web portal. Signatures are added on the server as mail is sent, in Outlook or Gmail as people type, or both, with details synced from Entra ID, Google Directory or an HR system. Higher plans add rotating banners, campaign scheduling, CRM-based targeting and engagement reports.

To get you started, here are 9 things to know about Exclaimer, taken from its own pages and our grades.

  1. 1

    Best for company-wide signatures on Microsoft 365 or Google Workspace

    Exclaimer runs signatures for a whole company from one web portal, added on the server or in Outlook and Gmail, from $0.90 a user.

  2. 2

    Paid plans start at $0.90 a month for each person

    As its pricing page puts it: $0.90 per user / month, billed annually (Starter).

  3. 3

    You can try it first

    14-day free trial, no credit card required

  4. 4

    It runs on Web

    Web.

  5. 5

    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.

  6. 6

    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.

  7. 7

    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.

  8. 8

    A 2.6 GPA, above 7 of 9

    That is against the other email signature tools we grade, on value, the free plan, features, ease of use and platforms.

  9. 9

    Keep it

    The plain part of Exclaimer you could make: email signature, templates, reports and qR codes. What surrounds it you could not. The 4 things listed below take a company, not a weekend.

The report card

Best for company-wide signatures on Microsoft 365 or Google Workspace

Exclaimer runs signatures for a whole company from one web portal, added on the server or in Outlook and Gmail, from $0.90 a user. But you pay for at least 10 users, Starter gives the whole company one template, and reports and CRM targeting wait for Pro.

ToolGPA report cardExclaimerGraded Oct 23, 2026
SubjectGradeComment
Value for moneyBStarter is $0.90 a user a month billed yearly, with a 10-user minimum, so the floor is $9 a month. One person pays that; a team of five pays $1.80 a head, inside this category's cheaper quarter at $2.00. Pro is $1.75 a user.
Free plan and trialCNo free plan, only a 14-day trial with no credit card needed.
FeaturesBServer-side and in-client signatures on every plan, directory sync, disclaimers, rotating banners, targeting rules and brand kits, with HR sync, CRM targeting and A/B tests on Pro. That's the whole job, though Starter allows one template.
Ease of useCNo app store rating on record. An admin connects Microsoft 365 or Google Workspace, syncs the directory and builds templates in the web portal before anyone gets a signature.
Platforms and integrationsBA web portal with Microsoft 365, Google Workspace, Exchange, HubSpot, Salesforce, Workday, BambooHR and Salesloft, and server-side signatures reach mail sent from phones. No desktop or phone app of its own.
Grade point averageGood, out of 4.02.6

An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

Who Exclaimer is for

  • 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

Who it is not for

  • 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

Good to know

Good for

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

Keep it

The plain part of Exclaimer you could make: email signature, templates, reports and qR codes. What surrounds it you could not. The 4 things listed below take a company, not a weekend.

It is one of the better ones too: its GPA of 2.6 is higher than 7 of the 9 other email signature tools we grade. It costs $10.80 a year.

What you could make

  • Email signature, templates, reports and qR codes: an app builder makes these well.

What you could not

  • Splitting visitors between versions and telling you which won.
  • It is priced for each person, which means accounts and billing for a team.
  • It plugs into other products, Microsoft 365, Google Workspace and Microsoft Exchange among them.
  • The depth: we grade its features B, which means it covers the whole job.

What this rests on. Exclaimer’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
