System Update // March 2026
AgentMailr is now Lumbox.
Same product, new name. Everything you were using still works — same API, same inboxes, same features. We just changed the name.
Why the change?
We received a trademark notice from AgentMail (agentmail.to), a YC-backed company in the same space. The name "AgentMailr" was too similar to "AgentMail" and was causing confusion among users. Rather than fight it, we chose to rebrand completely.
What changed?
01
Name: AgentMailr → Lumbox
02
Domain: agentmailr.com → lumbox.co
03
Dashboard: app.agentmailr.com → app.lumbox.co
04
API: api.agentmailr.com → api.lumbox.co
What didn't change?
Everything else. Your inboxes, emails, API keys, webhooks, credentials — all still work.
- check Existing @agentmailr.com inboxes still receive email
- check Old API URLs redirect to new ones
- check Old dashboard redirects to app.lumbox.co
- check New inboxes default to @lumbox.co
- check MCP server env vars have backward-compat fallbacks
Action required?
None. Old domains redirect automatically. Your API keys work on both domains. When you're ready, update your LUMBOX_API_URL env var — but there's no rush.
