Deduplicate creator contacts across several profiles

Use a deduplication worksheet to connect creator profiles, keep shared agency inboxes separate from people, and avoid duplicate campaign outreach.

Separate creator tokens connect to their own profile tiles while both link to one shared agency inbox.

To avoid treating one creator's accounts as separate prospects, give the creator one internal ID and attach each confirmed profile to it. Keep representation and campaign contact routes in separate records. A shared agency email can connect several creators without making them the same person. Deduplicate the people first, then review the messages you plan to send.

Keep three matching decisions separate

An email address tells you where a message goes. It does not establish who owns every profile that lists it. Microsoft's shared-mailbox documentation explains that several people can use one mailbox and send from it with the right permissions.

Use these three decisions in your worksheet:

DecisionQuestionRecord to keep
Creator identityDo these profiles belong to the same creator?Creator ID with linked profiles
RepresentationWho handles this creator's business inquiries?Representative or agency linked to the creator
Campaign contactWhere should this campaign's conversation go?Campaign, creator, chosen route and conversation owner

These are recommended recordkeeping rules. Social platforms do not prescribe this worksheet.

The separation also helps people manage relationships. Modash's article on influencer relationships recommends building relationships with talent managers and discusses assigning creators a single team contact. Your records should preserve both the creator relationship and the representative relationship.

Decide which profiles belong together

Start with the source profiles, before sorting by email. Keep the original profile URL and assign a temporary row ID so a later merge does not erase where the record came from.

Use this review order:

  1. Same profile. Two rows pointing to the same confirmed account are duplicate profile records. Keep one profile record and combine its source notes.
  2. Creator-owned connection. A creator's established website links to both accounts, or the established account identifies the other as theirs. Review the links and any conflicting details before assigning one creator ID.
  3. Possible match. Similar handles, names, portraits or content suggest a candidate for review. Keep the records separate until you have stronger evidence.
  4. Shared contact only. The same agency domain, manager name or inbox is evidence about the contact relationship. It is insufficient evidence for a creator merge.

For uncertain links, use the checks in verify that a contact page belongs to the creator. Avoid a universal similarity score that lets several weak clues outweigh contradictory ownership evidence.

A joint account needs an explicit decision. If two creators run a shared channel, record the joint project and its relationship to each person. Do not merge the people into one individual record because they share that channel.

Copy this deduplication worksheet

Keep one row per observed profile while reviewing. Repeat a confirmed creator ID across that creator's profiles. Repeated IDs are expected in this sheet.

FieldWhat to enter
Source row IDOriginal import or research row reference
ProfilePlatform and full profile URL
Creator IDYour stable internal identifier, independent of email
Match statusConfirmed, possible match or separate
Match evidenceSource URL, observed connection and review date
RepresentationAgency or representative, scope and source
Contact route IDIdentifier for the business inbox or contact form
Route scopeCreator-specific, shared representation or unknown
Campaign assignmentCampaign ID, selected route and team owner
Merge decisionSurviving creator ID, reviewer and reason

Preserve the address as supplied. Remove accidental surrounding spaces when preparing a comparison field, but do not strip dots, plus suffixes or other characters to manufacture a match. Route matching and creator matching remain separate decisions.

For source notes your next teammate can check, follow record where each creator email came from.

Shared-inbox counterexamples

The following worksheet is hypothetical. Names, IDs and contact routes are invented; inbox labels are identifiers rather than published addresses.

Observed recordsEvidenceDecision
Mira's Instagram and YouTubeHer established website links to bothAssign creator C01 to both profiles
Mira and LeonSeparate creator pages list agency inbox R01Keep C01 and C02; link both to R01
Mira's old and new contact routesHer current business page names a new representativeKeep C01; mark the old route superseded for new outreach
Two accounts named Mira StudioSimilar handles, no ownership connectionLeave as possible matches
Mira and Leon's joint channelTheir established pages identify it as a joint projectLink the project to both creators; keep their IDs separate

For a hypothetical autumn campaign, Mira's two profiles become one prospect assignment. Leon remains a second prospect even though R01 serves both people.

Now review the recipient queue. Two valid creator assignments can still produce repetitive emails to the same agency. Let one team owner decide whether to send a combined inquiry naming both creators or maintain separate, clearly named conversations. Follow any business-inquiry instructions the representative publishes.

Do not discard Leon's assignment merely because R01 already appears in the queue. That would remove a person when the duplicate was only a destination.

Check your CRM's import behavior

Before importing shared-inbox rows, read how your CRM matches contacts. HubSpot documents automatic contact deduplication by email, including blocking manual creation of another contact with an existing email address.

In a system with that behavior, filling each creator's primary email field with the same agency address can collapse information you meant to keep separate. Your spreadsheet's creator IDs alone do not prove the import will preserve that distinction.

Ask the CRM administrator how to store a shared representative and link the creator records to it. If the available setup cannot express that relationship, keep a separate creator register until an appropriate mapping exists. Do not invent alternate email spellings to force separate contacts through an import.

Test the mapping with hypothetical rows before loading your researched list. Inspect both the resulting creator records and the outbound recipient list.

Review the next send after merging

A confirmed identity match does not select a contact route or authorize a message. YouTube's business-inquiry help says an address is visible only when the channel owner has supplied one. That documents availability; it does not identify everyone behind the inbox.

Limit outreach to creator-welcomed business inquiries where applicable rules permit the message. Use the business-contact boundary guide before treating a public address as usable.

After a merge, check queued messages, existing conversations and any contact restrictions attached to either record. Pause conflicting assignments for review. Keep the surviving creator ID, the retired row references and the reason together so a teammate can understand or reverse an incorrect match.

Start with the repeated addresses in your next campaign list. For each group, decide whether it represents one creator, several creators sharing representation, or an unresolved match before releasing any messages.
