Burning a sending domain in week 2
A sequence that worked last month gets filtered to spam this month. You don’t know until reply rates collapse, and by then the campaign’s already half-spent.
Cold email that reaches the inbox. Domain after domain, sequence after sequence.
You can’t reply if you can’t see the message. Unspam catches placement problems across your entire sending pool (multiple domains, multiple inboxes, multiple sequences) before they cost you a whole campaign’s worth of replies.
The deliverability problems we hear most.
Multi-domain, multi-inbox sprawl
Cold ops at scale = 30 domains, 200 inboxes, all rotating. Nobody’s checking placement on each one weekly. The bad ones quietly drag down the whole campaign.
No early-warning system
A Google filter change can cut your reply rate in half overnight. Without daily monitoring you find out via the Friday metrics review, not on the day of.
Why teams like yours pick Unspam.
Health for every inbox in your rotation.
Daily placement check from each sending mailbox. The minute one drops below the threshold, pull it out of rotation before reply rate goes with it.
Daily blocklist checks for every domain.
40+ public blocklists, checked daily, alerted on listing. Catch a Spamhaus or Barracuda flag the morning of, not weeks later.
How it works.
01
Add every sending inbox
Connect unlimited sender accounts: one workspace handles your whole pool, whether that is 20 inboxes or 2,000.
02
Run a baseline placement test
See where each inbox currently lands at Gmail, Outlook, Yahoo, and corporate Google Workspace.
03
Schedule daily autopilot
Daily test from each inbox. Alerts when any specific sender starts slipping so you can pull it out of rotation.
04
Diagnose + recover
Auth check, content scoring, AI-generated remediation steps, including warmup recommendations when a domain needs to cool down.
A few common workflows.
The patterns outbound teams build around Unspam, from a single rep’s morning routine to a 100-inbox operation that pages on placement regressions.
-
New domain warmup verification
Run daily Autopilot checks during your 14-day warmup window. See placement climb from 40% to 90% before you put the domain into real campaign rotation.
-
Sequence-level placement check
Test each step in your 5-touch sequence, the second and third touches are where Gmail starts filtering. Adjust before reply rates drop.
-
Inbox rotation health dashboard
A single view of which inboxes in your pool are landing primary vs which are filtered. Pull the bad ones, accelerate the good ones.
-
Morning inbox-rotation triage
Sweep every sending inbox first thing. Pull the few that landed promotions or spam, replace them in your rotation, hit your campaign load before 9am.
-
Reply-rate-drop autopsy
Reply rates fell 30% Tuesday. Was it the copy, or did Gmail filter you? Compare yesterday’s placement test with last week’s and find out in a minute.
-
Pre-send compliance + auth check
Before pushing into a regulated region, verify your unsubscribe headers, list-unsubscribe-one-click, and from-domain auth all clear on a fresh test.
Frequently Asked Questions
How is this different from a warmup tool? +
Warmup tools simulate engagement to build reputation. Unspam measures what actually happens at the receiving end, inbox vs promotions vs spam vs missing. Use both: the warmup tool builds the reputation, Unspam tells you whether it worked.
Does it work with my SMTP / sequencer (Smartlead, Instantly, Apollo, etc.)? +
Yes. Unspam tests whatever arrives at our seed list, so the sender stack you use to deliver doesn’t matter. Smartlead, Instantly, Apollo, Quickmail, custom SMTP: all supported.
How many inboxes can I test from? +
Unlimited. Connect as many sender accounts as your sending pool needs. Quota is per test, not per sender, so your monthly test allowance is the only ceiling. Agency and White Label plans raise that allowance for large sending pools.
Can I monitor when a Google filter change hits us? +
That’s exactly the workflow. Daily Autopilot test from each sending inbox + alert thresholds. The morning Gmail tightens, every inbox in your rotation gets re-tested and the affected ones flag immediately.
Does this help with corporate Google Workspace placement? +
Yes. The inbox-placement test covers both personal Gmail and corporate Google Workspace seeds. Most cold-outreach tools only check personal Gmail, but B2B mail is going to corporate Workspace and they filter differently. Pair it with the email verifier on every list import to keep your sequences clean.
