How Sigil compares
The differences that matter when you’re managing signatures for a whole organisation on Microsoft 365.
SigilCodeTwo
How signatures are applied
One way only: an Outlook add-in that applies the signature as you write.
Cloud (server-side) mode, Outlook (client-side) mode through a centrally deployed add-in, or both together in combo mode.Source: CodeTwo user guide: overview
Mail routing
Your outbound mail is never routed through Sigil. There are no connectors and no transport rules.
Outlook mode keeps mail in place. Cloud and combo modes route mail through CodeTwo’s service hosted in Microsoft Azure.Source: CodeTwo user guide: overview
Coverage beyond Outlook
Outlook only. Mail from other clients (Apple Mail, printers, line-of-business apps) gets no signature, because there is no server-side mode.
Cloud and combo modes add signatures to mail from any client or device, after it is sent.Source: CodeTwo user guide: overview
Proof it’s working
Per-mailbox activity and a never-applied list, so you know exactly which mailboxes are covered.
Central deployment with signature rules that decide which users or groups get which template.Source: CodeTwo: Email Signatures 365
First deployment
Deployed through Microsoft 365 Integrated apps. Microsoft says a new add-in can take up to 24 hours to appear for every user.
The Outlook add-in is deployed the same way, from the Microsoft 365 admin center, so the same Microsoft timing applies.Source: Microsoft Learn: centralized deployment FAQ
Personalisation
Live from Microsoft Graph: 30+ attributes including 15 custom, with conditional sections.
Placeholders filled from Microsoft Entra ID attributes, with conditional placeholders and user photos.Source: CodeTwo: Email Signatures 365
Authoring
Drag-and-drop designer and full HTML control, with drafts, line diffs and versioned rollback.

Analytics & privacy
Click counts only: no IP addresses, no recipient identities, no message content.
Marketing banners with URL tagging so campaigns can be tracked in web analytics platforms such as Google Analytics.Source: CodeTwo: Email Signatures 365

Why teams switch
Everything you’d expect, and the parts you couldn’t get before
You can prove it’s working
Most signature tools can’t tell you who’s actually covered. Sigil shows per-mailbox adoption and a never-applied list, so nothing slips through.
One model, no rerouting
Sigil only ever applies signatures in the compose window, so senders see their own signature as they write. There are no connectors and no cloud mode routing your outbound mail through a third party.
Change it in seconds
Rebrand, fix a disclaimer or launch a campaign, then publish. The next message every user composes carries the change, with no redeploy and no waiting.
One simple price
£0.70 per licensed mailbox per month, excluding VAT, with every feature included. No tiers, no minimum seat count, and shared and group mailboxes are free.
Privacy by default
Read-only directory access and click-count-only analytics: no IP addresses, no recipient identities, no message content, ever.
Ready to send
A polished signature, ready to go
Sigil comes with a professionally designed signature template, pre-packaged and ready from the start, so you’re not building from a blank page. Prefer a seamless switch? Recreate your current signature exactly with the drag-and-drop designer or full HTML editor, then modernise it whenever you like.
Readysignature included: use it as-is or tailor
Switching is simple
Move from CodeTwo in three steps
- 01
Start your trial
Grant admin consent and deploy the Sigil add-in through Microsoft 365 Integrated apps. No card required. Microsoft can take up to 24 hours to push the add-in to everyone.
- 02
Set up your signature
Use Sigil’s ready-made template, or recreate your current signature exactly with the drag-and-drop designer or HTML editor, so the switch is seamless.
- 03
Switch it on
Roll out to a pilot group with assignment rules, confirm adoption in the dashboard, then turn off the old tool.
Switching questions
Moving over, answered
Will recipients notice the switch?
Only if you want them to. Sigil ships with a polished ready-made signature, and its designer and HTML editor let you recreate your current signature exactly, so you can make the switch seamless for recipients, or refresh the design at the same time.
Do I have to change my mail flow?
No. Sigil applies signatures client-side, inside Outlook as messages are composed. There are no connectors to configure and nothing rerouting your outbound mail. If you run CodeTwo in cloud or combo mode today, moving to Sigil lets you remove those mail-flow connectors.
Can I run both during migration?
Yes. Because Sigil is client-side and assignment rules let you pilot with a group first, you can trial it alongside your existing tool and cut over when you’re ready.
