Details
What is CodeTwo Email Signatures 365?
Email signatures are the one IT policy every employee breaks daily — people change titles, delete disclaimers, invent their own formatting — and CodeTwo built an entire business on ending that chaos for Microsoft 365 tenants. The Polish-bootstrapped vendor has specialized since 2007, and its flagship cloud service stamps centralized signatures, legal disclaimers, and rotating marketing banners into email server-side, meaning they appear correctly whether mail leaves Outlook on Windows, Apple Mail on an iPhone, or a browser tab of OWA; client-side mode adds the reverse option for users who want to see their signature while composing. Reviewers rate it 9.6 out of 10 across roughly 213 TrustRadius reviews — numbers rare enough at that review volume to make it the top-rated product in its category — praising fast setup, an admin panel non-specialists navigate comfortably, granular rules that scope by department or individual, live previews, and support that answers quickly with real expertise rather than scripts. Marketing teams get scheduling-driven banner campaigns with Google Analytics click tracking threaded through every employee's outgoing mail, which several reviewers cite as the ROI case by itself. The honest caveats: it is Microsoft-only without apology, the service sits inside your mail flow so its outages are theoretically yours, and automation faithfully reproduces whatever inconsistency lives in your directory. For any organization standardized on Microsoft 365 that wants signatures handled once, centrally, forever — this is the benchmark everyone else gets compared against.

Who is it for?
- Microsoft 365 organizations wanting brand-consistent signatures everywhere
- Marketing teams running banner campaigns through employee email
- Compliance-driven firms needing mandatory legal disclaimers
- MSPs managing signatures across multiple client tenants
- IT teams tired of chasing employees over outdated signature details
Who is it NOT for?
- Google Workspace organizations — full stop, wrong tool
- Mixed Microsoft-and-Google stacks needing unified coverage
- Tiny teams fine with hand-maintaining a few signatures
- Orgs unwilling to clean up directory data before automating
- Companies requiring zero third-party hops in mail delivery
The Bottom Line
CodeTwo Email Signatures 365 is as close to a solved problem as enterprise software gets: a 9.6/10 rating across 200+ reviews, Microsoft's only full certification in the category, transparent per-user pricing that drops with scale, and reviewers reporting double-digit hours saved every week. If your organization runs Microsoft 365 and email signatures matter to brand or compliance — and at any real size, they do — this is the default answer. Just go in knowing it is Microsoft-only by design, your directory data needs cleaning before automation will flatter you, and you are trusting a Polish vendor's servers with a hop in your mail flow. For everyone else, Exclaimer or SyncSignature covers the platforms CodeTwo deliberately ignores.
