What to Do If Your Email Is Blacklisted
Discovering that your email or domain is blacklisted explains a lot, but it does not solve the problem by itself. The next steps determine whether deliverability recovers or whether listings continue to return over time.
Confirm the scope of the listing
Start by identifying exactly what is listed.
Key questions to answer:
-
is the listing tied to a sending domain, subdomain, or IP
-
how many blacklists are involved
-
whether the blacklist is reputation-based, policy-based, or complaint-driven
-
whether the listing is active or historical
MailMoxie’s Blacklist Checker provides this context so listings can be evaluated by impact rather than treated equally, and MailMoxie’s email deliverability consulting team can help translate results into a prioritized remediation plan.
Identify what triggered the listing
Blacklist listings reflect patterns observed over time, not single sends. Common contributors include:
-
authentication gaps or misalignment
-
sudden increases in volume
-
low-engagement or purchased lists
-
high spam complaint rates
-
repeated bounces or unknown users
Pinpointing recent changes in sending behavior or infrastructure helps narrow the likely cause before attempting removal. When the root cause is unclear or multiple factors are involved, you can work with MailMoxie’s email deliverability consulting team to perform a structured analysis and remediation plan.
Review authentication and configuration
Before requesting removal, authentication should be reviewed and confirmed.
This usually includes:
-
SPF alignment and coverage
-
DKIM signing and validity
-
DMARC policy and reporting
-
consistent sending domains
Removal requests submitted without addressing email authentication issues often fail or result in relisting, and MailMoxie’s email deliverability consulting team can assist with configuration reviews and implementation support.
Understand removal expectations
Each blacklist operates independently. Some provide automated removal forms, others require waiting periods, and some do not accept requests at all.
Important considerations:
-
removal does not guarantee immediate inbox recovery
-
some listings expire automatically after behavior stabilizes
-
repeated removal requests without behavior changes increase scrutiny
MailMoxie helps clarify which listings are likely to resolve quickly and which require longer-term monitoring, and consulting services provide guidance on setting realistic expectations and next steps.
Monitor after removal
Removal is only one step. Many relistings happen within weeks because underlying signals were not fully addressed.
Post-removal monitoring typically focuses on:
-
reputation stability across sends
-
engagement trends
-
complaint and bounce rates
-
recurrence of blacklist signals
Ongoing checks help confirm whether remediation is holding or whether additional intervention is needed, and MailMoxie’s email deliverability consulting team can help interpret trends and recommend course corrections.
When blacklist issues keep returning
Recurring blacklist listings usually indicate broader sender reputation problems rather than isolated incidents.
At this stage, teams often need:
-
deeper analysis across sending streams
-
alignment between marketing, transactional, and automated mail
-
changes to list management and cadence
-
ongoing reputation oversight
MailMoxie surfaces these patterns early so escalation decisions can be made with data rather than guesswork, and consulting services can lead cross-team remediation when issues span multiple sending streams.
Get structured support to resolve the issue
Blacklist removal is often only one step in restoring stable deliverability. Domains that recover successfully usually address authentication, sending behavior, list health, and monitoring together rather than in isolation.
MailMoxie supports this process by combining blacklist visibility, authentication review, and consulting services in one place. Instead of guessing which signal is responsible or handling removal requests without context, teams can see how blacklist status connects to broader reputation factors.
For organizations that need deeper remediation or ongoing oversight, MailMoxie also supports guided analysis and structured resolution planning. This helps move from temporary removal to sustained deliverability stability.
Check your current status
