Manage contacts, duplicates, and blacklists

Use Signalist indicators together with the CRM and source data. When records or counts disagree, pause the affected action and investigate instead of assuming the system has resolved the conflict automatically.

Before you start

Agree on one team rule for duplicate contacts and repeated outreach.
Define who may blacklist a person or company and which reasons must be documented.
Confirm which system owns account and contact status when Signalist and the CRM differ.
Make opt-outs and legal suppressions non-negotiable exclusions.
Assign an owner for resolving ambiguous or conflicting records.

Read the available context together

Indicator	What it tells you	What to do
Other Lists	The person or company appears in another Signalist list.	Open the context and check ownership, status, and recent or active outreach before proceeding.
Outreach or previous activity	Signalist has recorded messaging or campaign activity for the contact where available.	Review timing, campaign state, replies, and the team rule for repeat contact.
CRM status and owner	The external relationship or account ownership may already be defined.	Follow the owner and handover rule; do not create parallel outreach.
Connected on LinkedIn	A LinkedIn relationship may already exist.	Check who owns the connection and whether the planned action fits the relationship.
Exclusion Reason	The record was excluded by a rule or workflow.	Read the exact reason and correct the source or rule only when the exclusion is genuinely wrong.
Found / Not Found	The source record was or was not matched during processing.	Sample the matches for accuracy and improve identifiers for unmatched records.

Decide whether a record is a duplicate

Do not merge or ignore records by name alone. Compare stable identifiers and relationship context. Two people can share a name, and one person can change company or role.

LinkedIn profile URL or another approved profile identifier
Business email address and current domain
Current company and role
CRM contact or lead identifier
Previous outreach, replies, and active campaign status
Record owner and most recent meaningful activity

If the identifiers conflict, keep the records out of outreach until the owner or support team confirms the correct identity.

Steps

**Clean the source before upload. **Remove obvious duplicate rows and records that should never enter the workspace.
**Open the processed list or Contacts view. **Add the columns or panels needed to see Other Lists, Outreach, Exclusion Reason, CRM status, owner, and relevant identifiers.
**Filter known or excluded contacts. **Separate records with previous activity, other-list membership, opt-outs, blacklists, or unresolved identity conflicts.
**Review each duplicate decision. **Compare profile, email, company, role, CRM record, owner, and activity. Do not decide from a name alone.
**Apply the team rule. **Keep, exclude, reassign, or escalate the record according to ownership and campaign policy.
**Add a blacklist entry only for a documented reason. **Choose the person or company scope deliberately and check the effect on other lists where the UI supports it.
**Review the affected sample. **Confirm that intended records are excluded and that unrelated contacts or companies were not blocked.
**Check again before activation. **Verify that the campaign or workflow excludes previous outreach, active campaigns, other lists, opt-outs, and blacklisted records as required.

Use blacklists deliberately

Blacklists can protect employees, private contacts, competitors, customers, opt-outs, or other records that must not enter a workflow. Document why the entry exists and whether it applies to one person or the whole company.

Never remove an opt-out or legal suppression simply to make a campaign run.
Use company-level blocking only when every relevant person at the company should be excluded.
Check whether the contact appears in other lists before confirming a blacklist change.
Review the visible result after the change; counts and derived states can require closer inspection.
When in doubt, keep the contact excluded and ask the responsible owner or support team.

Troubleshooting

Problem	Solution
A contact was approached despite appearing in another list	Pause the affected outreach. Check whether Other Lists, previous campaigns, or active-campaign exclusions were missing from the setup, then review the complete target segment.
A competitor appears as a lead	Add the company to the appropriate blacklist where supported or strengthen the competitor and DQ criteria in lead scoring. Confirm whether the exclusion should apply to the company or selected people.
The same person appears as multiple records	Compare profile URL, email, company, and role. Keep the best-supported record and escalate unresolved identity conflicts rather than merging by name alone.
A blacklist count or status looks inconsistent	Do not assume the visible count proves the final state. Open a sample, check affected lists and contacts, and ask support to investigate if the records disagree.
A Not Found record is a known person	Add stronger current identifiers such as company, role, domain, or an approved LinkedIn URL, then test a corrected source.

Frequently asked questions

Is a contact a duplicate just because they appear in two lists?

Not necessarily. Multiple list memberships can be valid. The risk is repeated or conflicting action, so check identity, owner, relationship history, campaign status, and team rules.

Should I merge contacts with the same name?

No. Compare stronger identifiers such as profile URL, email, company, role, and CRM record. Escalate conflicts instead of merging by name alone.

When should I blacklist a company instead of a person?

Use a company-level blacklist only when all relevant people at that company should be excluded. Use a person-level entry when the reason is specific to the individual.

What does Not Found mean?

It means the source record was not matched in that processing flow. Review current identifiers and source quality; it does not by itself prove that the person or company does not exist.

Can I remove an opt-out to contact the person again?

No. Treat opt-outs and legal suppressions as protected exclusions. Follow your organisation’s compliance process if the status is disputed.

What should I do if blacklist counts look wrong?

Open affected records and compare their actual list and contact states. Keep outreach paused and contact support when visible counts or statuses remain inconsistent.

Choose the right list source

Choose your list source by starting with what you already have and what you want the list to do next. If you begin with the source name alone, it is easy to pick something too broad, too narrow, or not available in your workspace.

Use LinkedIn list sources safely

LinkedIn activity can help you build timely lists from profile visits, followers, events, posts, engagement, or prepared LinkedIn URLs. Use the source that matches the specific signal, then qualify the people before you treat them as outreach candidates.

Use AI Company Search to describe target companies in natural language, and use news or signal monitoring to watch for specific events. Both work best when your prompt is verifiable, your exclusions are explicit, and each result has a defined review or follow up action.
