Add Warmup Phrases
After connecting Gmail via OAuth, add your warmup phrases so Underfive knows which emails to filter out from your master inbox.
Why Warmup Phrases Matter
When you use email warmup tools, they send automated emails through your mailbox. Warmup phrases tell Underfive to automatically remove these emails from your master inbox — so your AI agent only processes real lead replies, not warmup traffic.
Keeps Your Inbox Clean
Warmup emails are automatically filtered out, so only real prospect replies reach your AI agent.
Prevents Wasted Credits
Without warmup phrases, your AI agent might process warmup emails and waste reply credits.
How to Add Them
Connect Your Sequencer
Connect your email sequencer to automatically fetch warmup tags. Underfive pulls the phrases directly — no manual work needed.
Add Manually
Check your sequences for warmup subject lines or tags, then add them as warmup phrases in Underfive.
Add Ignore Phrases
Beyond warmup, you can add additional ignore phrases to filter out any other emails you don't want reaching your master inbox.
