Quality outbound at scale used to mean hiring armies of people to send a few emails a day. Za-zu unlocks anyone to send as many personalized emails as they want. From one inbox.
Send like a team of 50
Add as many accounts as you’d like and Za-zu will warm them up, then share sending across them.
Work from one inbox
One place for as many email accounts as you want to send from. See what’s important, reply, book meetings, and close deals.
Connect any number of email accounts
With Za-zu, cold email volume is finally unshackled from headcount. Send as many as you want, when you want.

Uncommonly Bold
Make every email personal—and valuable.
Land every email in the primary inbox, not spam.
We handle the complex backend deliverability work. You focus on sending your campaigns with peace of mind, knowing that your emails will land where people can see them.
When an account or domain starts hitting spam more often than it should, za-zu automatically swaps it out for a fresh, pre-warmed account to make sure your campaigns are performing at their best.
Send like a human
za-zu automatically does something called spintaxing: introducing controlled randomness into your campaigns via slight changes in wording, so your sending looks more natural. Maintain complete control over what words za-zu does and doesn’t use.
Warm your inboxes automatically
Our network of 100,000+ accounts interacts with your inboxes and domains to build your sender reputation while you sleep. So when it’s time to send, you can be confident your emails won’t hit spam.
Cold email is powerful. But it needs better infrastructure.
For years, we’ve been deeply interested in outbound. Some of us built Aurora, a cold email agency that has driven more than $1B in pipeline. Others built Clay, the data enrichment tool.
We love outbound because it is uniquely powerful: one person with a laptop could scale a company from $0M to $1M ARR in a matter of months just by sending emails. But unlike other forms of marketing, you can’t just crank the dial on outbound. Today’s email sequencers are clunky, limited, and nearly impossible to use at scale. We think you should be able to simply crank the dial. That you should have an intelligent email sequencer that just works out of the box. That this sequencer should be intuitive, powerful, and dare we say it—even enjoyable. That is why we are building Za-zu.
