About

What is Newoldstamp

Newoldstamp lets you build HTML email signatures from templates, apply brand assets, and push them to every employee's inbox from a single dashboard. It's aimed at marketing teams and agencies managing signature consistency across solo operators or SMBs up to 50 seats. The standout capability is its banner-based marketing campaigns embedded directly in signatures — you can run promotions, track impressions, and measure click-through rates without touching your ESP. Directory sync with Active Directory and Google Workspace means new hires get the right signature automatically. Where it falls short: there's no API access, so you can't automate signature updates programmatically or plug it into a broader ops workflow without manual intervention.

Our verdict

Vanderbuild take

For marketing teams and agencies that need every outbound email to carry consistent branding, Newoldstamp is a focused utility — it does one thing and doesn't try to be a full ESP. On the agentic readiness front, there's no API and MCP status is unknown, so you can't drive this from an agent or automation layer without scraping the UI — it's strictly a human-operated tool. At $6/month to start, the cost of testing is low, and the annual per-seat pricing stays manageable for small teams. The honest ceiling here is scale and automation: once you need to trigger signature updates from a CRM event or orchestrate changes across hundreds of seats programmatically, you'll hit a wall fast.
