Warmy warms inboxes. InbXr reads the list you're warming for.

What Warmy is

Warmy automates the warmup process for new sending domains and cold email infrastructure. It sends and replies to emails across a network of seed inboxes to build sender reputation over time. If you're setting up a new domain or rehabilitating a burned one, Warmy is the category leader.

What Warmy does well

• Automated warmup send and reply loops
• Sender reputation ramp-up over weeks
• Integrations with cold email platforms
• Warmup score tracking over time

Signal coverage

InbXr reads 7 Inbox Signals across 100 weighted points. Warmy covers:

Not a signal reader. Warmy is an action tool, not a diagnostic layer.

What Warmy doesn't read

• Signal 01 · Bounce Exposure (no list verification)
• Signal 02 · Engagement Trajectory (no MPP detection on your list)
• Signal 03 · Acquisition Quality (no cohort reading)
• Signal 04 · Domain Reputation (partial, sender-side only)
• Signal 05 · Spam Trap Exposure (no dormancy reading)
• Signal 06 · Authentication Standing (surface-level)
• Signal 07 · Decay Velocity (no score history)

Side by side

When Warmy is enough

If you're a cold email operator building up a new domain for outbound, Warmy handles the reputation ramp well. Keep it.

When you need InbXr instead

Warming your domain doesn't matter if the list you're sending to is already broken. Before and during warmup, you need to know which contacts will bounce, which will report spam, and which signals are trending toward deliverability collapse. That's what InbXr reads.
