Sigmint vs CodeTwo
CodeTwo, through CodeTwo Email Signatures 365, is an enterprise signature-management service that applies signatures centrally across an organization's Microsoft 365 mailboxes, both server-side in mail flow and via a client-side add-in. Because signatures are managed centrally, they stay consistent and under IT control across every device. It's a per-user subscription that requires connecting to your Microsoft 365 tenant and admin configuration.

Pricing
A per-user recurring subscription for the whole organization, versus Sigmint's one-time payment for an individual.
Best for
Built for IT-managed organizations that need central control, consistency, and compliance across many mailboxes; Sigmint is for individuals and small setups.
Setup
Requires connecting to your Microsoft 365 tenant and admin configuration, whereas Sigmint works instantly in the browser with no signup.
Outlook rendering
CodeTwo can apply signatures server-side, a very reliable way to keep them consistent across Outlook and every device, but it needs admin deployment; Sigmint gives you Outlook-ready copy-paste with no IT involvement.
Data privacy
Signatures are managed and applied through CodeTwo's cloud service connected to your mailboxes; Sigmint keeps everything client-side with nothing leaving your browser.
When CodeTwo is the better choice
- → You administer Microsoft 365 and need consistent, centrally enforced signatures across the organization.
- → Compliance requires disclaimers applied server-side to every outgoing message.
Support you can actually reach
Sigmint is a small tool, and that is a support feature: when you email hello@sigmint.app, the person who wrote the code reads it — there is no ticket tier, no chatbot maze, and no “business hours in another timezone”. If something doesn’t work, it gets fixed or you get your money back under the 14-day no-questions refund policy. With platform products, support quality usually depends on which plan you bought.
The verdict
CodeTwo is the right tool for organizations that want centrally managed, server-applied signatures with IT oversight across Microsoft 365. Sigmint is for the individual who just needs one good signature without a platform, an admin, or a subscription.
Frequently asked questions
Is Sigmint an alternative to CodeTwo?
Only at the individual level. CodeTwo applies signatures server-side across a Microsoft 365 organization — the right tool for IT-enforced consistency and compliance, priced per user. Sigmint is the two-minute, $12-max answer for one person who just needs an Outlook-safe signature.
Does CodeTwo work for a single freelancer?
It is not built for that: CodeTwo requires Microsoft 365 tenant integration, admin setup, and per-user organizational licensing. A freelancer gets the same visual result by pasting Sigmint’s table-based HTML into Outlook directly.
Why do IT teams choose server-side signature tools like CodeTwo?
Because mail-flow injection guarantees every message from every device carries the correct, compliant signature without user action. That guarantee matters at organizational scale — and is unnecessary overhead for individuals, which is the gap copy-paste generators like Sigmint fill.
