Company email signatures

Company email signatures — controlled from one place.

Every email your company sends is a marketing surface. SignatoryGrid keeps that surface on-brand across every teammate and inbox.

Frequently asked

How do I standardize signatures across the whole company?

Design one signature in the brand editor. Every employee gets a claim link that renders their name, role, and contact info inside your brand template.

What if the company rebrands?

Change the brand color, logo, or tagline once. Every claim link updates and employees re-paste to refresh.

Do you support multiple departments?

Yes. Assign roles or team labels per employee to customize what shows up in each signature.

Is company data secure?

Data is encrypted in transit and at rest. We never share or sell your team's information.
