CodeTwo vs Signature 365 (2026): which should you pick?

Pick CodeTwo if

• Fits if your company is on Microsoft 365 and wants signatures on mail sent from phones
• Works for IT teams that also set company-wide out-of-office replies

Look elsewhere if

• Skip it if you're on Google Workspace, which its product page doesn't mention
• Not for you if you want a free plan, as there's only the 14-day trial
• Watch out: we couldn't confirm a price, because CodeTwo's site turned our reader away with a bot check
• Watch out: it's managed in a browser console, with no app beyond the Outlook add-in

Pick Signature 365 if

• Fits if you run Microsoft 365 for 10 or more people
• Works for companies that want the same signature and campaign banner on all mail

Look elsewhere if

• Skip it if you use Google Workspace, since it targets Microsoft 365 only
• Not for you if you have fewer than 10 users, as the minimum is 10
• Watch out: licenses count every user and shared mailbox, signature or not
• Watch out: it is not covered by the 30-day money-back guarantee on Symprex's other software
• Watch out: cancelling ends the subscription at period end and the data is deleted

CodeTwo

• CodeTwo's website turned our reader away with a bot check, so its prices could not be confirmed from page text.
• The service is built for Microsoft 365; its product page does not mention Google Workspace.
• There is no free plan, only the 14-day trial.
• Management happens in a browser console; there is no separate desktop or mobile app beyond the Outlook add-in.

Signature 365

• It is built for Microsoft 365 and Office 365; the pages mention Exchange Server only as the target of a separate Symprex product.
• The minimum is 10 users, and licenses are counted for each user and shared mailbox whether or not a signature is added.
• Signature 365 is not covered by the 30-day money-back guarantee that Symprex states for its other software.
• Cancelling terminates the subscription at the end of the billing period, and Symprex deletes all related data when a subscription is terminated.

CodeTwo

Cloud and Outlook signatures

Signatures are added in the cloud after sending, so mail from any client or phone gets one, or by an Outlook add-in as people type. Either mode or both can be used.

Outlook add-in deployed centrally

The Outlook add-in, which runs in Outlook on Windows, Mac, the web, iOS and Android, is rolled out from the Microsoft 365 admin center with no install by staff.

Entra ID placeholders and rules

Signatures pull names, titles and photos from Microsoft Entra ID, and rules pick a signature by sender, recipient or user attributes.

Organization-wide autoreplies

Sets company-wide automatic replies and out-of-office messages from the same browser console.

Campaigns and surveys

Schedule marketing banners with tagged links for web analytics, and add one-click customer satisfaction surveys to signatures.

Data kept in Azure regions

Mail is relayed through Azure-hosted services, and settings can be kept in a chosen Azure region; CodeTwo says it does not store emails.

Signature 365

Central dashboard

All signatures and campaigns for the company are created, managed and monitored from one dashboard, with a template library to start from.

Segmentation by department

Each department, or individual users, can be given different branding, information and calls to action.

Directory details

Contact details and headshots are pulled from the directory, with social links and banners added to every signature.

Campaigns and analytics

Banner campaigns and surveys can be added to signatures, with tracking of clicks, impressions and conversions plus reports.

Legal disclaimers

Signatures and disclaimers can be created and assigned so that outgoing mail carries required legal text.

Outlook add-in and mail routing

Signatures reach mail either through an Outlook add-in or through email routed via the Signature 365 service, and the vendor says recipients are not prompted to download images.
