How do I activate server-side imprinting?

You can enable cloud deployment during initial onboarding via the Connect option on your Exclaimer dashboard. To set it up later, go to the Settings menu, select Mail Flow , then choose Connect to (your preferred email platform) . Follow the on-screen instructions to authorize Exclaimer and set up server-side imprinting.

Does cloud deployment add any security risks to our email flow?

No. Emails are routed through Exclaimer’s Azure-based service within your local region, using email platform connectors. No email content is stored, and security standards such as ISO 27001, ISO 27018, and GDPR compliance are built in. Data is encrypted end-to-end with TLS protection, and advanced security measures such as firewalls, intrusion prevention systems (IPS), and active DDoS protection are in place to defend against cyber threats.

Can users change or remove their signatures?

No. Because signatures are applied server-side after the email is sent, end users can’t alter or bypass them. This guarantees that every message carries the approved signature and required disclaimers.

Will users see their signature while composing an email?

Because signatures are applied in the cloud, they aren’t visible while the user is writing their message. However, Exclaimer Cloud can also be paired with our Outlook add-in or Google Workspace app. This gives users a live preview of their signature as they type, while still ensuring the approved signature is applied server-side after sending. However, applied signature visibility in the sent items folder can be toggled on in your mail flow settings for both M365 & Google Workspace.

What happens if Exclaimer is unavailable — will our emails still be delivered?

Yes. Email delivery is never interrupted. Our 24/7/365 monitoring automatically detects any service alerts, with escalation chains that notify Exclaimer’s senior technical team immediately. In the highly unlikely event that the signature service at a regional datacenter is affected, your organization’s emails will not be lost. As soon as the issue is resolved, email continues to be sent as normal, with signatures resuming automatically. Exclaimer also uses high-availability clusters, automated load balancing, and continuous data synchronization to ensure seamless failover. Scheduled updates are deployed during off-peak hours, and the service is stress-tested to guarantee reliability.

Brand Kits are Exclaimer’s central place for managing brand assets across employee communications. They store approved logos, fonts, colors, banners, meeting backgrounds, and disclaimers in one kit and apply them consistently across connected email signatures and video meetings, so employee communications stay on-brand automatically.

Who are brand kits for?

Brand Kits are perfect for organizations managing multiple brands, regions, departments, or subsidiaries—especially those going through rebrands, growth, or M&A activity.

How do I access Brand Kits?

Brand Kits are available with all Exclaimer plans. Log in to your Exclaimer account and go to Settings (Cog icon) > Brand Kits to create or edit your Brand Kits.

How do Brand Kits keep email signatures consistent?

Regardless of how complex your organization's structure may be, brand assets are stored and managed in one place. When assigned to signatures, Brand Kits ensure every employee email follows the correct brand guidelines.

What types of assets can I manage with Branding?

With Brand Kits, you can define logos, icons, fonts, colors, and banners for all of your brands, offices, regions etc. These assets are then available to use in any email signature design, for any of your teams. Pro users can enjoy this same brand-consistency on their organization’s meeting backgrounds using our Meeting Branding feature .

How do I add a brand asset to a new signature?

For each signature, select your brand kit from the dropdown. Then, when you add text or image assets in the Signature Designer, your assigned Brand Kit defaults (fonts, colors, and logos) are applied automatically. For example, when adding an Image/Logo element, simply select “Brand Image” as the source to choose from the pre-defined assets stored in the Brand Kit.

How do I upload and manage brand images?

Within Brand Kits, you can upload up to three images in different shapes, add alt text and hyperlinks, and make them available for use in your signatures.

Can I add assets while creating a signature if none are uploaded yet?

Yes. A placeholder appears will appear If there are currently no brand images defined. Once you upload your images to the assigned Brand Kit, they’ll automatically update in your design. For more information, see How to use Branding in a signature .

Can I preview changes before they go live?

Yes. While updates apply automatically, you can review them in the Signature Designer to confirm everything looks correct before finalizing and deploying to your users.

How do Brand Kits save time when managing email signatures?

Centralizing brand assets into set Brand Kits for each of your brands eliminates repetitive tasks like re-uploading the logos or defining colors and copying hex codes for every signature, across each of your brand's templates. Updates to every Brand Kit applies everywhere it is linked, reducing manual work, cutting down on errors, and streamlining brand management at scale.

Exclaimer has been the leading email signature management solution for 25 years and is the simplest way to manage email signatures at scale. Exclaimer is the only email signature management platform with Brand Kits—keeping assets in one place and updating them everywhere automatically.

Background

Dunlop Protective Footwear designs and manufactures protective footwear for industries including agriculture, poultry farming, oil and gas, and mining.

Dunlop had worked with Exclaimer for years, managing email signatures centrally through an on-premises deployment. When the company set out to move its email environment from on-premises Exchange to Microsoft 365, that signature management had to move too, without losing the centralized control or consistent branding already in place. Across 400 mailboxes and roughly 200 workstations, there was no room for anything to fall out of step during the switch.

Before

Email signature management tied to on-premises servers due for retirement
No clear path to Microsoft 365 without rebuilding email signature deployment from scratch
Any inconsistency during the switch would touch every mailbox at once

After

Email signature management fully hosted in Exclaimer's cloud solution
The same centralized control and branding carried straight over to Microsoft 365
No on-premises software left for IT to maintain

Dunlop's challenge

Moving 400 mailboxes to a new email platform is disruptive enough on its own. Dunlop needed to do it without rebuilding the centralized email signature management the business already relied on.

The IT team faced a few specific pressures:

Platform migration risk: Shifting from on-premises Exchange to Microsoft 365 meant re-establishing email signature deployment on new infrastructure, with no room for inconsistency mid-migration.
Continuity of branding: Every email signature needed to look and function exactly as it had before the switch, keeping the Dunlop logo and legal compliance standards intact across all outgoing mail.
Operational scale: With around 200 workstations and 400 mailboxes to move, any manual step in the process multiplied the chance of error or downtime.
Zero margin for error: Employees across Dunlop's global operations needed to keep working without noticing any change to how their email signatures behaved.

How Exclaimer helped

Exclaimer's cloud solution gave Dunlop a way to move to Microsoft 365 without starting its email signature management over. The centralized control the IT team already relied on carried straight across to the new environment.

With Exclaimer, Dunlop could:

Move without rebuilding from scratch: Bring email signature deployment onto Exclaimer's cloud platform without recreating templates or rules, so the switch to Microsoft 365 didn't mean starting over.
Keep every email signature consistent: Apply the same branding and formatting across every mailbox, with the same logo and legal compliance standards carried over automatically.
Retire on-premises servers: Remove the need for local infrastructure dedicated to email signature management, since everything now runs from Exclaimer's cloud platform.
