Warm mailboxes before you scale outreach.
Connect Google Workspace and Microsoft 365 mailboxes. LeadVector exchanges realistic email between them, rescues messages from spam, ramps volume gradually, and tracks a health score so you know when a mailbox is ready to send.

How it works
1
Connect Google or Microsoft
OAuth connection, no passwords stored. LeadVector verifies the mailbox as soon as it is connected.
2
Warmup runs on its own
Mailboxes exchange scheduled messages with each other. Opens, replies, and rescues from spam are simulated at configurable rates.
3
Watch the health score
Sent, received, replied, inbox, and spam counters roll into a score. Cooldowns kick in automatically when a mailbox needs a rest.
Traffic that looks like real email.
Warm-up messages are created and scheduled with randomised timing, sent through the real provider, and read from the receiving inbox. Anything that lands in spam is found and moved back.
Randomised scheduling, with a weekday-only option
Gradual daily ramping with hourly and daily limits
Messages found in spam are moved to the inbox

Health you can act on.
Every mailbox and domain carries counters, a warm-up score, and a status. When health drops, LeadVector applies a cooldown and resumes when it recovers. Campaigns only pick healthy mailboxes.

Questions
Common questions about warmup.
Which providers are supported?
Google Workspace and Gmail, and Microsoft 365 and Outlook, connected through OAuth.
How long should I warm a mailbox?
LeadVector ramps volume gradually and shows a health score. Most teams wait until the score is healthy before assigning the mailbox to a campaign.
Can I pause warmup?
Yes. Pause and resume any mailbox from the app or the API. Warmup also pauses itself with a cooldown when health drops.
