WiseStamp, CodeTwo, Exclaimer and Other Email Signature Software Alternatives

Quick answer: pick CodeTwo if you run on Microsoft 365 and want a low per-user price. Pick WiseStamp, Newoldstamp or Exclaimer if you want a visual designer and campaign analytics. Pick MySignature for a simple per-user tool with tracking. Pick Email Signature Magic if you run on Gmail or Google Workspace, or you are a brokerage that needs license numbers and Equal Housing handled as real fields.

Searches like "WiseStamp competitors" and "CodeTwo alternative" are usually from someone deciding between a handful of tools, not hundreds. Here are the ones we compare, in plain terms. Every fact comes from the vendor's own public pages or a clearly attributed review site, as read in September 2026, and each tool has its own page with the sources linked.

The short version

• CodeTwo: a mature, low-priced tool built for Microsoft 365. We found no Gmail support on its site.
• WiseStamp: a visual and AI designer, campaign banners with analytics, and Gmail and Outlook coverage, with per-employee pricing on higher plans.
• Exclaimer: an enterprise tool for Microsoft 365 and Google Workspace with directory sync, rules-based disclaimers and analytics.
• Newoldstamp: a full platform with banner campaigns, analytics and automation for Google Workspace and Microsoft 365, priced per signature.
• MySignature: a well-reviewed tool at $6 to $7 per user per month billed yearly, with a free plan, email tracking and digital business cards.
• HubSpot's free generator: a one-time tool. You build a signature, copy it and paste it into each email app yourself.

How the signature actually gets applied

This matters more than the feature list. Some tools add the signature on the server after you hit send, so the sender does not see it while composing. Some use an Outlook add-in or a browser extension. Some write the signature into each person's Gmail signature setting through the Gmail API. Which is right depends on whether your people mostly use Gmail, Outlook on desktop, or phones, and whether you need to prove what was live on a given day.

Where each one is the right choice

• You are all-in on Microsoft 365 and want the lowest per-user price: CodeTwo.
• You want a drag-and-drop designer and click analytics on banners: WiseStamp or Newoldstamp.
• You are a larger organization that needs directory sync and rules-based disclaimers across Microsoft 365 or Google Workspace: Exclaimer.
• You are a small team that wants a simple per-user tool with email tracking: MySignature.
• You want a good-looking signature once, free, and are happy to paste it yourself: a free generator.
• You run on Gmail or Google Workspace, or you are a brokerage that needs a license number, MLS ID, designations and Equal Housing as structured fields, with office and team templates: Email Signature Magic.

Where Email Signature Magic is not the better choice

We would rather you pick the right tool. If you are all-in on Microsoft 365 today, CodeTwo is more mature there, with Outlook add-in and server-side options we don't have yet; our Outlook add-in is still in development. We also have no click analytics dashboard, no free-form drag-and-drop designer (we offer ten fixed layouts), and no Entra ID directory sync. If those matter most, one of the tools above fits better.

What it costs, in one place

Prices change, so confirm them on each vendor's site. As of September 2026: our Solo plan is $15 a year, Starter is $0.69 per member per month (10-member minimum) and Growth is $0.89. CodeTwo's yearly rate started around $1.22 per user per month at 10 to 25 users and falls with volume. WiseStamp's published team plans started at $9 per month for one admin and up to 10 members at $2 each, then a platform fee plus $1 per employee. Each comparison page works the same arithmetic at 10, 50 and 200 members.
