Exclaimer: centrally managed email signatures, done properly for Microsoft 365 and Google Workspace
Exclaimer is the leading cloud platform for managing email signatures across an entire organisation. Instead of every user maintaining their own signature in Outlook or Gmail (with the inevitable inconsistency, missing disclaimers, and outdated phone numbers) Exclaimer applies a single, controlled signature to every email sent from your domain, updated centrally and consistent across every device.
For agencies and professional services firms where email is one of the most visible expressions of the brand, this matters more than it sounds. A scruffy or inconsistent signature undermines the work you do everywhere else. Equally, for businesses with legal disclaimer requirements or marketing campaigns running through email, central control isn’t optional.
Dr Logic deploys and runs Exclaimer for clients as part of ongoing managed IT support. We handle setup, template design coordination, ongoing updates, and the integration work with Microsoft 365 or Google Workspace. This sits inside our IT Success® Plans, so signatures are part of how we deliver IT support rather than a separate vendor relationship for your team to manage.
What Dr Logic delivers with Exclaimer
- Deployment and tenant integration. We set up Exclaimer against your Microsoft 365 or Google Workspace tenant, configure the routing properly so signatures are applied to every email regardless of which device or app the user sent from, and verify it’s working across desktop, mobile, and webmail.
- Signature template implementation. We work with your design team or in-house marketing to implement the signature template properly in Exclaimer, including logos, social icons, legal disclaimers, and any role-specific elements. If you don’t have a template, we’ll work with you to build one that’s clean and renders correctly across mail clients.
- User data and Active Directory or JumpCloud integration. We connect Exclaimer to your directory so names, job titles, phone numbers, and office details flow automatically into signatures from one source of truth. Update the directory, the signature updates. No manual edits, no version drift.
- Campaign banners and marketing additions. Where it’s useful, we set up rotating campaign banners or event promotions within signatures so marketing has a controlled channel for promoting things via everyday email, without users having to update anything themselves.
- Multi-brand and multi-domain handling. For clients with multiple brands, trading names, or sub-domains, we configure Exclaimer to apply the right signature to the right brand based on the sender, so everyone gets the correct signature without overlap.
- Ongoing updates and changes. When you rebrand, change office address, add a legal disclaimer, or update the marketing banner, we handle the change in Exclaimer rather than asking your team to do it. One ticket, fixed across the whole business.
- Signature consistency on mobile and webmail. This is the bit native solutions get wrong. Exclaimer applies the signature server-side, so it works the same whether someone sent the email from Outlook on a Mac, Gmail on a phone, or webmail from a hotel laptop.
Why Exclaimer
Exclaimer is the established leader in this space, and for good reason: it works. The integration with Microsoft 365 and Google Workspace is solid, signatures render correctly across mail clients, and the management console is genuinely usable. Dr Logic’s team has hands-on experience deploying and managing Exclaimer across many client environments, and we run it alongside our Apple Premium Technical Partner work and the wider Microsoft 365 and Google Workspace platforms we support.
When Exclaimer is the right fit, and when it isn’t
Exclaimer is almost always the right call for businesses that care about brand consistency in email, have multiple offices or brands, or need central control over legal disclaimers and signature content. It’s particularly valuable in agencies, professional services firms, and any business where email is a primary client touchpoint.
That said, if you’re a five-person business where everyone manages their own signature in Outlook and it’s never caused a problem, Exclaimer is probably overkill. There are also cheaper alternatives like CodeTwo Email Signatures for Microsoft 365, which is a credible competitor with similar features and is sometimes a better fit on price. Wisestamp sits at the lower end of the market and works for smaller setups. For most businesses in the 70 to 150 user range, Exclaimer wins on reliability, support, and feature depth.
We’ll be honest about whether you actually need a signature management platform at all, and if you do, which one fits best. Get in touch and we’ll talk it through.
What is Exclaimer?
Exclaimer is a cloud-based email signature management platform for Microsoft 365 and Google Workspace. It applies a consistent, centrally managed signature to every email sent from your domain, regardless of which device or app the user is using.
Do you manage Exclaimer for clients, or just set it up?
We manage it. Initial setup, template implementation, ongoing changes, directory integration, and any troubleshooting are all handled as part of an IT Success® Plan. When you need to update the signature, you ask us, we do it.
How does Exclaimer work with Microsoft 365 or Google Workspace?
Exclaimer connects to your tenant and routes outbound email through its service to apply the signature server-side. This means signatures work consistently whether someone is on Outlook desktop, Outlook mobile, the web app, Gmail, Apple Mail, or any other client. The user doesn’t need to do anything.
What about mobile signatures? They've always been a mess.
This is the main reason most businesses move to Exclaimer. Because signatures are applied server-side after the email leaves the device, mobile email gets the same proper signature as desktop. No more “Sent from my iPhone” appearing under client emails.
Does Exclaimer help with Cyber Essentials or compliance?
Exclaimer isn’t a security product, but it helps with compliance in adjacent ways. Centrally controlled legal disclaimers, GDPR statements, and regulatory wording stay consistent and current across every email the business sends. For regulated sectors, that consistency matters.
How does Exclaimer compare to CodeTwo or Wisestamp?
CodeTwo is the closest competitor and a credible alternative, particularly for Microsoft 365 environments. Pricing and features are broadly similar, with some differences in management console and template flexibility. Wisestamp sits lower in the market and tends to suit smaller businesses. For most businesses in the 70 to 150 user range, Exclaimer is the safer pick, but we’ll be straight about whether CodeTwo is the better call for your specific situation.
Is Exclaimer worth the cost for a business our size?
For most businesses in the 70 to 150 user range, the answer is yes, particularly if email is central to how you work and brand consistency matters. The time saved (and the inconsistency avoided) typically outweighs the per-user cost. We’ll model it against alternatives before recommending it.
Ready to Strengthen Your Email Signatures?
If you’re tired of inconsistent signatures, struggling to enforce legal disclaimers, or planning a rebrand that needs rolling out across every email overnight, we’d be happy to talk through whether Exclaimer (or something else) is the right answer.
