Migration Guide

Migrate from Exclaimer to Siggly

Exclaimer relies on Exchange transport rules and M365 connectors to inject signatures server-side. Siggly replaces that complexity with a streamlined cloud deployment that gives you more design flexibility, real-time analytics, and lower costs.

Why Teams Migrate from Exclaimer

Zero Downtime Migration

Run Siggly in parallel with Exclaimer during the transition period. Signatures never go dark.

Template Import

Export your existing Exclaimer HTML templates and import them directly into Siggly's editor for refinement.

User Data Preserved

Siggly syncs with Azure AD and Google Directory, so all employee data maps automatically — no re-entry needed.

No Transport Rules Required

Eliminate fragile Exchange transport rules. Siggly deploys signatures at the client level or via API, avoiding mail-flow disruption.

Parallel Running Period

Keep Exclaimer active while you test Siggly with a pilot group. Cut over when you are fully confident.

Step-by-Step Migration from Exclaimer

1

Audit Current Transport Rules

Document your existing Exclaimer transport rules in Exchange Online or on-premises Exchange. Note which rules handle signature injection, disclaimers, and conditional logic.

2

Export Templates & Assets

Save your Exclaimer signature HTML, banner images, and social icons. Siggly can import raw HTML directly.

3

Configure Siggly & Sync Directory

Connect Siggly to Azure AD or Google Workspace. Map user attributes (name, title, phone, department) to dynamic template fields.

4

Recreate Signature Rules in Siggly

Set up department-based or role-based signature assignments in Siggly. Use conditional content blocks to replicate Exclaimer's rule logic.

5

Pilot with a Test Group

Deploy Siggly signatures to a small team while Exclaimer remains active for everyone else. Validate rendering across Outlook, Gmail, and mobile clients.

6

Disable Exclaimer Transport Rules & Go Live

Once validated, disable Exclaimer's Exchange transport rules and roll Siggly out to all users. Remove the Exclaimer connectors from your M365 admin center.

"We had 14 transport rules in Exchange just for signatures. Siggly replaced all of them in one afternoon and our IT team finally stopped getting support tickets about missing signatures."

Frequently Asked Questions

How do I export my Exclaimer templates?
In the Exclaimer admin console, navigate to each signature template and copy the HTML source. Save banner images and icons separately. Siggly can import the raw HTML directly into its template editor.
How long does the migration typically take?
Most organizations complete the migration in under 2 hours. Complex setups with many conditional rules may take half a day. Our support team can help with planning.
Can I run Exclaimer and Siggly at the same time?
Yes. During the parallel running period, Exclaimer continues to apply transport-rule signatures while Siggly deploys to your pilot group. There is no conflict between the two systems.
What happens if I need to roll back?
Simply re-enable your Exclaimer transport rules in Exchange Online. We recommend keeping them disabled (not deleted) during the first week after cutover.
Do my users need training on Siggly?
End users need zero training — signatures are deployed automatically. Admins typically need 15-30 minutes to learn the Siggly dashboard, and our onboarding guide walks through every step.
