Blacklist recovery

Bounces spiking. “550 rejected.” You're listed.

The listing you found in a bounce message is rarely the only one. One scan checks 45+ sources, shows which listings actually hurt you, and walks you through each provider's removal process until monitoring confirms you're clean.

The recovery playbook

Seven steps from listed to trusted.

Clean is the halfway point. The last two steps are the ones people skip, and they are why the same domain gets listed again.

Step 1

Scan everything, immediately

Add the domain, its subdomains and your sending IPs (bulk import if there are many). A full scan runs the moment each asset is added, across all 45+ blacklist and reputation sources, so you find every listing, not just the one that showed up in a bounce.

Step 2

Triage with the per-source breakdown

The 0-100 reputation score is deterministic, with a per-source breakdown and trend history. See exactly which listings are dragging the score and start with the ones doing real damage.

Step 3

Follow the guided delisting walkthrough

For each listing, a walkthrough opens with that provider's own removal process. No hunting through provider docs mid-incident: submit the request where it actually gets handled.

Step 4

Let monitoring confirm the clear

Monitoring keeps rechecking and auto-confirms when the delisting clears. Scheduled rechecks run as fast as every minute by plan, so a relisting is caught in minutes, not the weeks it took to notice this one.

Step 5

Fix the root cause

Deliverability checks validate SPF, DKIM, DMARC, MTA-STS and BIMI, verify per-IP PTR and FCrDNS, and watch MX changes and TLS certificate expiry, hourly by default. Broken auth and missing reverse DNS are how clean senders get flagged.

Step 6

Prove you actually recovered

Delisted is not the same as trusted. Run an inbox placement test and read the real folder at Gmail, Microsoft 365, Yahoo, Zoho and AOL, because a domain can be clean on every source and still land in Promotions or Spam. Content analysis scores the delivered copy at the same time, so if the wording is what is holding you back you see the specific lines.

Step 7

Rebuild the trust you lost

A listing costs sending history, not just a place on a list. Inbox Boost ramps the domain back over 28 days with real engagement, stepping volume up only when the previous days hold, and pausing itself if bounces cross 2%. This is the part that stops the same incident happening twice.

  • Re-scan on demand after each delisting request, with a short cooldown
  • Score-drop alerts to email, Slack or HMAC-signed webhooks the moment anything regresses
  • Check Gmail's view via the Google Postmaster integration: domain and IP reputation, spam rate, auth compliance
  • Premium feeds on paid tiers widen coverage across reputation APIs

Questions

Mid-incident questions, answered honestly.

How do I know which blacklists I am on?
Add your domain and sending IPs and a full scan runs immediately across 45+ blacklist and reputation sources, including Spamhaus ZEN, DBL and DQS, Barracuda, SpamCop, SORBS, SURBL and URIBL, plus reputation APIs like Google Safe Browsing, Cisco Talos, Validity, IPQualityScore and Abusix. You get a per-source breakdown, not just the one listing you already found in a bounce message.
Do you delist me automatically?
No, and be wary of anyone who claims they can. Delisting always happens with the blacklist provider itself. What SenderSignal does is open a guided walkthrough of that specific provider’s removal process the moment a listing is detected, then keeps rechecking and auto-confirms in the dashboard when the delisting clears.
How fast will I know when a listing clears?
Monitoring rechecks on the interval you set, with a floor set by your plan: 15 minutes on Professional and as fast as every minute on Business and Enterprise. You can also trigger a manual re-scan anytime with a short cooldown. When the source stops listing you, the listing is auto-confirmed as cleared and an alert fires to email, Slack or a signed webhook.
Will this just happen again?
It can, if the root cause is still there. That is why the plan ends with deliverability checks: SPF, DKIM, DMARC, MTA-STS and BIMI validation, per-IP PTR and FCrDNS, MX change detection and TLS certificate expiry, run hourly by default on paid plans. Fix the misconfigurations that got you flagged, and keep score-drop alerts on so a relisting is caught in minutes, not weeks.
Can I start while I am mid-incident, without a card?
Yes. The free tier covers your first domain with no card, and the 30-day trial includes the deliverability checks. Bulk import exists if you need to add a fleet of domains and IPs at once; every asset gets its full scan immediately on add.
