Manage contacts, duplicates, and blacklists

Signalist keeps every person you work with in one place, across all your lists, and makes sure people who must not be contacted never are. This article covers where your contacts live, how the blacklist and competitor list work, and how Signalist avoids contacting the same person twice.

Where your contacts are

In the sidebar:

  • Contacts → Contacts: every person across all your lists. Search with Search contacts..., narrow with Filter, and choose columns with Select columns. Click a row to open the lead panel.
  • Contacts → Companies: the companies behind your contacts.
  • Do Not Contact → Competitors: companies you compete with. They are excluded from every list and search.
  • Do Not Contact → Blacklist: people and companies that are never contacted.

Select rows in Contacts to use the bar at the bottom: Add to (a list, your CRM, or the tracker), Enrich (Search for Email (1 credit), Search for Phone (10 credits)), Add to Blacklist, and Export. See Filter contacts, choose columns, and export.

The Contacts page with lead names, score, company, job title, and role change columns.

The blacklist

A blacklist entry stops Signalist from contacting a person, or everyone at a company:

  • Leads that match a new entry are moved to the Blacklist bucket of every list straight away.
  • New leads are checked when they are added to a list.
  • Every message is checked again right before it is sent. A blocked step shows "… blocked" in the Outbox.

The Blacklist page lists the newest entries first. Its search finds a person by name or email, and a company by its name or website.

Add entries

  • By hand: on the Blacklist page, click Add Entry and fill in a Domain, Email, LinkedIn URL, or LinkedIn Company URL. Choose the Scope: Person, Organization, or Auto (infer from data). An organization entry needs a domain or a company URL.
  • From a file: click Upload CSV and upload a file with the columns domain, email, linkedinUrl, and linkedinCompanyUrl (Download Example CSV shows the format). Choose whether it blocks People and companies, People only, or Companies only. A company entry blocks every lead at that company.
  • From a lead: select contacts and choose Add to Blacklist, or in a list choose Add to → Add to Blacklist. Signalist first shows which of them are on lists and that their campaigns will stop. In a list, Select → All covers every lead that matches the list's current search, filters, and tab, including leads on other pages.
  • Unsubscribe: the Unsubscribe button in the Inbox and in Review to send records that the lead unsubscribed.
  • By the lead: a lead who clicks the unsubscribe link in your email (the Unsubscribe Link variable) is added automatically.

When you blacklist a lead, you can also blacklist their company. The switch names the company, for example "Also blacklist Acme GmbH (acme.com)". This is the company the lead works at now, which is not always the company your list was built for. For several leads, the switch says how many companies it blocks. If no company is known for a lead, the switch is off and says so. If you chose Select → All in a list, the switch reads Also blacklist the companies of the selected leads and blocks the company each of those leads works at now.

The Blacklist page shows where each entry came from under Origin: "Unsubscribed by lead", "Blacklisted by user", "Imported by user", or "Competitor".

Remove entries

Select people on the Blacklist page and choose Remove from Blacklist. Tick Also remove organization from blacklist to lift a company-wide block as well.

A lead who unsubscribed always stays on the blacklist. Their row shows Unsubscribed instead of a remove option, and if you select them together with others, Signalist removes the others and names the people it kept.

Snooze hides a person until a date you choose; Unsnooze ends it early.

Contact a blacklisted lead

Sometimes you do want to reach someone who is on the blacklist, for example a person your team blocked by mistake. When you add blacklisted leads to a campaign, write to one, or take leads out of a list's Blacklist bucket, Signalist asks first. The window lists:

  • Taken off the blacklist: the leads that can be contacted. Their entries are removed, and they move to Found with the reason "Included by a user".
  • Stay on the blacklist: leads who unsubscribed ("Unsubscribed — cannot be contacted") and leads blocked by a Signalist-wide entry. They are never contacted.

If a lead is blocked because their whole company is on your blacklist, tick Also remove … from the blacklist to contact them. This unblocks everyone at that company. If the company is a competitor, it stays marked as a competitor for everyone else, and only the person you chose is let through.

After you confirm, Signalist tells you which leads stayed on the blacklist.

Competitors

Signalist recognises competitors from the Competitor description in your Lead Scoring settings. When a lead's company matches it, the lead is moved to the Blacklist bucket with the reason "Competitor", and the company is added to your competitor list. The Dashboard tells you when new competitors were found, with a Review them button.

On the Competitors page:

  • Add competitors adds companies by domain or LinkedIn company URL, one per line, or from a CSV file.
  • Not a competitor removes a company from the list, brings its leads back, and stops Signalist from flagging it again.

Avoid contacting someone twice

  • Only add new leads: in a list's settings, switch on Only add new leads that have not been added to other lists before. Leads already on another list are then simply not added to this one.
  • Other Lists and Company on other lists columns in a list show where a person, or their company, already appears. Both can be sorted.
  • Filter in a list offers Already on other lists for the person and Company is on other list for their company. Is not empty shows leads that are on any other list of your workspace, Is empty those on none, and Is in or Is not in lets you pick lists. Leads whose company is not known are not shown by the company filter.
  • The lead panel shows labels such as On other lists, In active campaign, Previous outreach, and Connected on LinkedIn.

Signalist keeps one record per person, so the same person on two lists is still one contact with one history. There is no need to merge records by hand.

Why a lead was excluded

A list sorts its leads into four buckets, which you choose with the Show filter: Found, Unsure, Not found, and Blacklist. Each bucket expands into the reasons behind it, for example "Job title excluded", "No contact details found", "Excluded manually", "Competitor", or "Unsubscribed". Found also shows "Included by a user" for leads someone took off the blacklist. The Exclusion Reason column shows the reason for each lead.

To move leads yourself, select them and use Status: Exclude from list moves them to Unsure and out of campaigns; To Found brings them back. With Select → All, a move covers every lead that matches the list's current search, filters, and tab, including leads on other pages. For blacklisted leads, Signalist asks first, as described above.

Troubleshooting

A company was wrongly flagged as a competitorOpen Competitors and choose Not a competitor, and sharpen the Competitor description in Lead Scoring.
A list has fewer leads than expectedOnly add new leads may be switched on, so people already on other lists were not added.

Frequently asked questions

What is the difference between the Blacklist and Competitors?

The Blacklist stops outreach to specific people or companies. Competitors are companies you compete with; Signalist finds them automatically and excludes them everywhere.

Can I undo a blacklist entry?

Yes, for entries you or your team added: select the person on the Blacklist page and choose Remove from Blacklist, or contact the lead from a list and confirm. A lead who unsubscribed always stays on the blacklist.

Does a blacklist entry stop messages that are already scheduled?

Yes. Every message is checked again right before it is sent.

Which company does "Also blacklist" block?

The company the lead works at now. The switch shows its name, and its website or LinkedIn page when we have them.

Does Select → All blacklist leads on other pages too?

Yes. With Select → All, Add to Blacklist and Status cover every lead that matches the list's current search, filters, and tab, on every page. If you searched for a name, only the leads that match the search are included.

How do I stop the same person from being added to several lists?

Switch on Only add new leads that have not been added to other lists before in the list's settings.

How do I see leads whose company is already on another list?

In the list, click Filter, set Company is on other list to Is not empty, and click Confirm. To check specific lists, choose Is in and pick them.

Do I need to merge duplicate contacts?

No. Signalist keeps one record per person across all lists.
