Gmail email signature generator: the 8 best tools in 2026

Signature Satori does one thing: it writes signatures into the Gmail accounts of a Google Workspace domain. You connect it as an admin, it imports names, titles and phone numbers from your Google directory, and it pushes one template to everyone. Its Google Workspace Marketplace listing shows more than 991,000 installs and a 4.8 rating, the strongest Gmail-only record we found.

Its pricing is the one to understand. A credit sets or changes one signature for one user; it costs $1.10, you buy at least 10, and once used it stays open 24 hours for unlimited edits. A team of 10 that changes its signature once a year pays $11. The subscription costs $1.11 per user per month, 5 users minimum ($5.55 a month), and adds unlimited signature changes and the marketing planner for banners. You can mix both: subscribe your sales team, put everyone else on credits. Every account starts with 5 free credits, no card needed.

The limit: it only manages Google Workspace accounts. A signature it writes into Gmail also shows when that account sends from Outlook or Apple Mail, but if part of your company has Microsoft 365 mailboxes, look at Exclaimer or BulkSignature. The subscription is monthly in the app; a six-month or yearly term is arranged on request.

Signitic is a French signature manager that works with Google Workspace and Microsoft 365 on every plan, free one included. Its Gmail add-on is listed on the Workspace Marketplace with more than 275,000 installs.

The free plan covers up to 19 employees with 1 signature template, and a Signitic badge appears at the bottom of each signature. Standard costs €1 per user per month, excluding VAT, with a minimum of 20 licences, removes the badge and unlocks unlimited templates and banner campaigns. Prices are shown in euros even on the English site.

For a small company on Gmail, it is the cheapest way to get the same signature on every account without anyone copying and pasting. Plan for the badge: if your brand can't live with it, the 20-licence minimum makes the bill €240 a year, even for 10 people.

Exclaimer manages signatures for Google Workspace, Microsoft 365 and Exchange from one console. Every plan can be deployed server-side (the signature is added as the email passes through the mail server, so it also lands on emails sent from a phone), client-side, or both.

Starter costs $0.90 per user per month billed annually, Standard $1.45 and Pro $1.75; Enterprise is quoted. The minimum is ten users, so even a team of three pays for ten: $108 a year on Starter. For 50 users, Starter comes to $540 a year. The trial lasts 14 days. Starter gives one signature template; Standard adds unlimited templates, signatures by department and scheduled banners.

Choose it when part of the team works in Outlook, or when signatures must also appear on mobile sends. For a pure Gmail company of under ten, the minimum makes it dearer than Signature Satori or Signitic. One trap from a 2026 user report: when the trial ended, the user's outgoing emails were rejected until support extended it, so decide before day 14. Already on Exclaimer and leaving?

HubSpot's generator is a web form: you type your name, title, contacts and social links, pick a template and colors, then copy the result into Gmail. It is completely free, with no trial and no account required, offers 12 templates, and the signature works in Gmail, Outlook, Apple Mail and Yahoo Mail.

To add it to Gmail, click Settings, then See all settings, paste it in the Signature section and click Save Changes at the bottom of the page. The logo is not hosted for you: you upload it to an image host and paste its direct URL, and HubSpot advises against Google Drive for that. If the signature doesn't display properly, HubSpot suggests copying the source code instead of the signature.

The limit is the one of every free generator: nothing is managed. Each person makes and pastes their own signature, and when your logo or address changes, everyone has to do it again. Past three or four people, a manager such as Signitic's free plan saves that work. The generator needs no HubSpot product; if you are weighing its CRM too, read our HubSpot review.

BulkSignature is a Gmail signature manager with more than 588,000 installs on the Workspace Marketplace. Like Signature Satori, it reads your Google directory and updates every account from one template; unlike it, the same plan also syncs Microsoft directories and covers Outlook mailboxes.

Its Standard plan starts at $1.10 per user per month for 10 users, with a minimum of 10 seats, and the price per user drops as the team grows; yearly billing costs 20% less. At 100 users, it is $0.76 per user per month billed monthly ($76 a month), or $0.61 billed yearly ($60.80 a month). That makes it the cheapest per-user subscription on this page for a large domain.

For a team under ten, the 10-seat minimum is the catch, and a credit pack from Signature Satori costs less if you rarely change your signature.

MySignature is a staple of comparison guides, next to WiseStamp. Its editor has a large template library and a Canva integration, and its paid plans add email tracking in Gmail (whether your email was opened).

The free plan gives one signature per email address with limited functions and MySignature branding. Core costs $6 per user per month, billed yearly, with 1 signature per user; Connect costs $7 and adds a second signature (for replies and forwards) and a digital business card. Both plans are presented as best for individuals or businesses with up to 5 team members. Past 5 people, the Teams plans add Google Workspace and Microsoft 365 automation: Standard at $2.40 per user per month and Engage at $3.40, billed yearly.

At $72 a year for one person, it costs more than a free generator, and a team of 10 on Teams Standard pays $288 a year, more than the Gmail managers above. It earns its place if you want a polished design and open tracking in one tool. When you cancel, signatures and online cards stop working at the end of the billing cycle. If you need tracking tied to deals and contacts, a CRM built for Gmail does more.

Newoldstamp prices by signature: a slider runs from 1 to 200, and 5 signatures cost $109 billed annually, shown as $1.80 per signature per month. Past 200, it is quoted. It connects to Google Workspace and Microsoft 365 for automatic deployment, and adds banner campaigns and click analytics.

The trial lasts 7 days, and you can create and edit signatures during it but not use them until you upgrade. When the subscription expires, the signature stops working. It also offers a separate free signature generator for one-off signatures.

It suits a team of 5 to 20 that wants banner campaigns without Exclaimer's 10-user minimum. Its per-signature price stays higher than Signature Satori or BulkSignature for a pure Gmail domain.

WiseStamp is the name nearly every comparison guide covers, and its Google Workspace app has more than 1 million installs. For one person, its Chrome extension syncs the signature to Gmail in one click.

Every plan is billed annually. Pro+ costs $9 a month for one signature with Gmail and Outlook sync, and adds up to 10 team members at $2 a month each. Basic, the first plan with Google Workspace integration and automatic installation, costs $19 a month plus $1 per employee: $348 a year for 10 people. Server-side signatures, the ones that also reach emails sent from a phone, only start on Platform at $189 a month plus $1 per employee. The trial lasts 14 days, with no card, and paid plans carry a 14-day money-back guarantee.

Its Workspace Marketplace rating is 3.8, the lowest of the big Gmail apps, and its average on a large consumer review site is 3.4 out of 5. Reviews from 2026 describe annual plans that renewed without a reminder, and a refund refused after renewal, the reviewer being told refunds only apply in the first 14 days of the first year. If you buy it, note the renewal date, and if you are already leaving, read how to switch from WiseStamp.
