Email signature tools, compared.

Last updated November 8, 2026. Written by Email Signature Gen.

There are three ways to give a team email signatures: a one-off generator, a hosted tool that manages one signature per person, or rules on the mail server. Email Signature Gen is the hosted, per-person kind: you install by copy and paste, and the images and banners stay on a link you control.

Which one fits depends on whether people can paste their own signature, whether mail sent from phones must carry it, and who has admin access to your mail system.

The three approaches

One-off generator

Often free, like HubSpot's.

How it's installed: You copy the HTML once and paste it into each mail app. You host the images yourself, or the tool does.
On phones: Only where you paste it. The Gmail app and iPhone Mail take a text signature of their own.
Banner changes without a reinstall: Not usually. A new banner means everyone pastes a new signature.
Admin access needed: None.
Usual price model: Often free. There is no team management.

Hosted, per person (Email Signature Gen)

$1 a person a month.

How it's installed: Each person copies their signature and pastes it into their mail app, from a no-login install link.
On phones: The same as any pasted signature. Mail sent from the Gmail app uses your Gmail web signature unless you set a mobile one. iPhone Mail takes text only.
Banner changes without a reinstall: Yes. Banners change in place. A text, layout or photo change needs the person to paste again.
Admin access needed: None for the install. A Google Workspace admin only if you import the directory.
Usual price model: Per person with a signature. A custom domain is $10 a month, and banners are $10 a month.

Server-side rules

Transport-rule tools.

How it's installed: The mail server adds the signature to each message as it is sent. Nobody pastes anything.
On phones: Yes, mail sent from phones included.
Banner changes without a reinstall: Yes. The server adds the current one to each new message.
Admin access needed: Microsoft 365 or Google Workspace admin access.
Usual price model: Usually per user, with more admin features.

When Email Signature Gen fits

You want one consistent signature per person, managed in one place, for a company, a team, or clients you set up as an agency.
People can paste their own signature into Gmail, Outlook or Apple Mail. Each gets a link that needs no login.
You want banners you can schedule and change without asking anyone to paste again.
You want the images on a link you control: a name like acme.emailsignaturegen.com, or a subdomain you own.

When it doesn't

Every message must get a signature from the mail server, including mail sent from phones. That needs a server-side tool.
You want to track opens. We don't.
You need signatures archived for compliance.

A text, layout or photo change also reaches a person only after they paste the signature again. The app shows who needs to and resends their links, but it can't change a signature already in someone's mail app.

Questions

Is Email Signature Gen a server-side signature tool?

No. Each person pastes their signature into their own mail app, and nothing changes on your mail server. If every message must get a signature from the server, phones included, a server-side tool fits better.

Do I need admin access to Microsoft 365 or Google Workspace?

No. Each person pastes their own signature, from a link that needs no login. A Google Workspace admin is needed only if you want to import people from the directory.

What do I pay for?

$1 a person a month, for each person with a signature, however many signatures they have. Contacts and teammates are free. A custom domain is $10 a month, and banners are $10 a month, each per organization.
