HA CreativesMade for the inboxes your clients actually use
seña handles the parts that usually end up scattered across design files, spreadsheets, browser tabs and client emails.
Build email-safe signatures across eight production-ready layouts with precise typography, color, spacing, assets, CTAs and social styles.
Run compatibility checks for Apple Mail, Gmail and Outlook before a signature reaches a real inbox.
Follow client-specific steps, copy formatted signatures, export HTML and record real-message tests.
Create client workspaces, import employees from CSV, generate signature variants in bulk, reuse brand presets and disclaimers, and package everything for handoff.
seña is local-first. Client workspaces, employee CSVs and signature projects are stored locally unless you deliberately export or use a remote hosted image.
Designed for freelancers, studios, agencies and teams who care about every detail that leaves the inbox.
