Deliverability & warmup
Deliverability is where cold outreach quietly leaks money. My Haze Pro includes both halves of the fix: warmup builds the reputation that gets you into the inbox, and the deliverability suite watches your sends in real time and acts before a bounce spike torches your domain.

Start warmup on every sending mailbox
Any connected Gmail, Outlook, or SMTP mailbox can join the warmup pool, which trades realistic email with other warmed mailboxes and ramps your volume over about 21 days.

Run the preflight before you send
Deliverability preflight checks your content spam-score and verifies SPF, DKIM, and DMARC, so you catch a broken DNS record before it costs you a campaign.

Watch bounce and complaint rates
The Deliverability screen tracks bounce and complaint rates live, per channel.

Trust the auto-pause
Any channel that crosses a 5% bounce rate pauses itself automatically, protecting your sender reputation before real damage lands.

Let suppression run
A managed suppression list keeps unsubscribes and known-bad addresses out of every sequence, across every channel — you don't maintain it by hand.
Pro tips
- Warmup is included on every plan — it is not a separate subscription.
- Don't disable warmup once you scale; leave it running in the background so your signals stay natural.
