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.
- Existing @agentmailr.com inboxes still receive email
- Old API URLs redirect to new ones
- Old dashboard redirects to app.lumbox.co
- New inboxes default to @lumbox.co
- MCP server env vars have backward-compat fallbacks
