MailSign vs WiseStamp (2026): which should you pick?

Pick MailSign if

• Fits if you are one person who wants a tidy signature without paying
• Works for companies that want to talk to sales about a deployed signature

Look elsewhere if

• Skip it if you want a team price on the page, because none is published
• Tight if you use the free generator, since you copy the signature into Gmail or Outlook yourself
• Watch out: deployment, sync and audit logs are team features only
• Watch out: Outlook signatures need the MailSign add-in, and the Gmail route needs Google Workspace

Pick WiseStamp if

• Fits if you want one signature on personal Gmail or Outlook.com and don't mind a WiseStamp line under it
• Works for small teams on Google Workspace or Microsoft 365 that want new hires' signatures installed for them

Look elsewhere if

• Tight if you're staying free, as the free signature only works on personal webmail and carries WiseStamp branding
• Pricey if you want banner campaigns and click tracking, which start on Grow at $49 a month plus $1 a person
• Pricey if you need signatures on phones with no setup: server-side signatures need Platform at $189 a month plus seats
• Watch out: Basic, Grow and Platform have a 3-seat minimum, and the prices shown are billed yearly
• Watch out: the pricing page's FAQ says there's no free version, while the help centre describes the Free plan in detail

MailSign

• Team pricing is not published; companies contact the vendor and are set up by hand.
• The free generator produces a signature you paste in yourself; deployment, sync and audit logs are team features.
• Outlook signatures depend on the MailSign add-in being installed, and the Gmail path needs Google Workspace.

WiseStamp

• The Free plan works only with personal webmail, not a company domain, and adds a WiseStamp line under the signature.
• Basic, Grow and Platform charge a base fee plus $1 per employee a month, with a minimum of 3 seats; prices shown are billed annually.
• Server-side signatures, which apply on phones without any setup, need Platform at $189 a month plus seats.
• The pricing page's FAQ says there is no free version, while the help center describes the Free plan in detail.

MailSign

Free signature generator

Anyone can build a signature from 10 layouts with their own logo, colors and links, then copy it into Gmail or Outlook.

Gmail deployment

After connecting Google Workspace, an admin edits the template and deploys it, and every mailbox gets the new signature.

Outlook add-in

Outlook users sign in with a Microsoft account and the add-in, listed on Microsoft AppSource, adds the right signature.

Locked fields and permissions

Admins choose which fields staff can edit, such as name or phone, while logo, layout and colors stay locked.

Directory sync

Titles, phone numbers and photos can be entered in MailSign or synced from Azure AD or SFTP, and new hires get a first signature from the company default.

Audit log

Team accounts include an audit log of changes.

WiseStamp

Signature studio and AI designer

Build a signature in a drag-and-drop editor from templates, or have the AI designer draft one from a prompt or logo. The AI designer is not on the Free plan.

Directory sync and auto-install

Connects to Google Workspace or Microsoft Entra to add new hires, keep names and titles current and install signatures without each person doing it.

Client-side and server-side deployment

Signatures go out through the Chrome extension, an Outlook add-in or the desktop app, or from the server on Platform and Enterprise so they apply on every device.

Banner campaigns and analytics

From Grow, schedule clickable banners in staff signatures and track impressions and clicks. Branded short links carry UTM tags.

Surveys in the signature

Embed one-click NPS, CSAT or custom surveys in signatures and have AI Insights summarize the answers. Platform can import results from other survey tools.

Rules and disclaimers

Lock legal disclaimers by department or region and send a shorter signature on replies and forwards. Targeting rules start on Grow.
