Can I add App Store and Google Play buttons to our signatures?

Yes. Firma supports App Store and Google Play badges as signature blocks, so every email from your team can drive app installs. You can also add a "Book a demo" or "Start free trial" button.

Does Firma work with Google Workspace and Microsoft 365?

Yes. On Google Workspace, Firma installs from the Marketplace and deploys across your company's Gmail accounts. On Microsoft 365, you deploy the Firma Outlook add-in from your admin center.

Can we promote a launch or funding announcement in signatures?

Yes. Schedule promotional banners for a product launch, a Product Hunt feature, or a raise. Update them once and every signature reflects the change.

Does it scale as we hire?

Yes. Signatures are generated from a central template, so every new hire gets a correct, on-brand signature the moment they are added, with no manual setup.

Is there a free plan?

Firma is free for up to 2 users, with per-seat pricing from $1.20/user/month billed annually ($1.50 monthly) and volume discounts as your team grows.

Signature drift makes a fast-growing startup look unpolished

When everyone sets their own signature, your brand fragments into mismatched logos, random fonts, and missing links, exactly when investors, customers, and candidates are forming a first impression of your company.

Firma lets you design one product-forward template and deploy it to every account, with branding, app badges, and buttons applied automatically and updated everywhere at once.

Built for how software teams actually grow

One signature across the whole company

Keep sales, success, product, and founders on-brand with the same logo, colors, and layout, no matter who hits send.

Drive installs and demos

Add App Store and Google Play badges, a "Book a demo" button, or a link to your changelog, right in the signature.

Works with Google Workspace and Microsoft 365

Deploy across Gmail with a 1-click Marketplace install, or to Outlook with the Firma add-in from your Microsoft 365 admin center.

Promote launches and funding news

Schedule banners for a new release, a Product Hunt launch, or a raise, and update every signature at once.

Scale with every hire

As the team grows, new employees get the correct, on-brand signature automatically, no setup on each laptop.

Update once, sync everywhere

Rebrand, change a title, or swap the app badge once and it propagates to every signature instantly.

Roll out company-wide signatures in minutes

Design your company template

Build an on-brand signature with your logo, product colors, app badges, and a demo or sign-up button.

Install for your domain
