Exclaimer review (2026): is it worth $0.90 a month per user, billed yearly?
Company-wide email signatures for Microsoft 365 and Google Workspace
Our verdict
First of our top three email signature tools
For: Companies of 10 or more on Microsoft 365 or Google Workspace
Exclaimer runs signatures for every mailbox from one web portal and, on every plan, adds them on the server as mail leaves, phones included, or in Outlook and Gmail as people type. Details sync from Entra ID or Google Directory, and disclaimers go on every email. Starter is $0.90 a user a month billed yearly. Know the limits: licensing has a 10-user minimum, so the floor is $9 a month; Starter gives the whole company one template and one banner; reports, CRM targeting and HR sync need Pro at $1.75; and there is no free plan, only a 14-day trial.

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.
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 Exclaimer 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
Why Exclaimer gets a 2.6
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- BValue for moneyStarter 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.
- CFree plan and trialNo free plan, only a 14-day trial with no credit card needed.
- BFeaturesServer-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.
- CEase of useNo 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.
- BPlatforms and integrationsA 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.

Keep Exclaimer, or make your own?
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.
What is Exclaimer?
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.
Worth knowing
- Licensing is per active mailbox, with a minimum of 10 users.
- Starter allows one signature template; separate designs per department need Standard.
- Engagement reports, HubSpot and Salesforce targeting and HRIS sync are Pro features.
- Monthly billing is offered, but the pricing page shows only the annually billed prices.

- 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.

- 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.
- Targeting rules
- Use different signatures for internal and external mail, exclude users or groups, and on Pro target banners at HubSpot or Salesforce lists.
