How to Find a Supply Chain Manager's Email Address (2026)

You find a Supply Chain Manager's email by looking it up in a data source first and guessing from a name pattern only when the lookup is empty. A lookup returns an address someone has already checked. A guess is a coin flip you must verify.

Supply Chain Manager addresses come from four places. A data provider holds a work address it collected and checked. The company site often lists only a shared inbox such as info@. A name pattern gives you a guess. A personal address sits in some records but suits business outreach poorly.

Only the first is worth building a process around. This guide uses the LeadOcean API, and every step has a request you can run.

TL;DR

• It takes about 15 minutes to size the audience, find one Supply Chain Manager's address and check its status.
• The walkthrough spends about 4 records: up to 3 from the search and 1 from the reveal. Counts are free.
• Send only to verified, catch_all_valid or catch_all. Anything you guessed gets verified first.

Prerequisites

• A LeadOcean API key from app.leadocean.io. The free plan has 1,000 records, one-off, and no card.
• The key in your shell as $LEADOCEAN_API_KEY.
• curl and jq.
• A target company domain. The examples use acme.com.

export LEADOCEAN_API_KEY="paste-your-key-here"

Step 1: Size the Supply Chain Manager audience for free

Count how many Supply Chain Managers you can mail before you spend a record. Send count=true and limit=1 as query parameters. Arrays go comma-separated.

curl -s -G https://api.leadocean.io/v1/people/search \
  -H "x-api-key: $LEADOCEAN_API_KEY" \
  --data-urlencode "title=Supply Chain Manager" \
  --data-urlencode "jobLevel=Manager" \
  --data-urlencode "salesRegion=EMEA" \
  --data-urlencode "emailStatus=verified,catch_all_valid,catch_all" \
  --data-urlencode "count=true" \
  --data-urlencode "limit=1" | jq '.meta | {total, totalIsExact, countOnly}'

salesRegion takes NORAM, LATAM, EMEA or APAC. Swap in country=DE for one market. REST meta.total stops at 100,000, so a very wide filter can return a floor with totalIsExact false.

Step 2: Find the Supply Chain Manager at your target company

Search by company domain and title. The search returns a thin row with no address in it. The row carries a person_id and flags that say whether we hold an email.

curl -s https://api.leadocean.io/v1/people/search \
  -H "x-api-key: $LEADOCEAN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "domain": ["acme.com"],
    "title": ["Supply Chain Manager"],
    "jobLevel": ["Manager"],
    "limit": 3
  }' | jq '.data[] | {person_id: .meta.source_ids.person_id, contact_data}'

Each person returned costs 1 record. Keep limit small. Title values are keywords, so a few rows may carry a neighbouring title such as Senior Supply Chain Manager. Read the title before you pick one.

The title is not standard. The same job appears as Logistics Manager, Supply Planning Manager, Demand Planning Manager or Inventory Manager. When Supply Chain Manager returns little, filter on function instead: "jobFunction": ["Supply Chain & Logistics"] with "jobLevel": ["Manager", "Director"]. Size it with count=true first.

Step 3: Reveal the address

Send the person_id to enrich with reveal_email set to true. Enrich takes exactly one of linkedin_url, email, phone or person_id. There is no name plus domain lookup, which is why Step 2 comes first.

curl -s https://api.leadocean.io/v1/people/enrich \
  -H "x-api-key: $LEADOCEAN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"person_id": "PERSON_ID_FROM_STEP_2", "reveal_email": true}' \
  | jq '.data.contact_data | {email_status, contact_emails}'

This costs 1 record. A person we hold nothing for is a 404 and costs nothing. If you only want a deliverable work address, GET /v2/people/email/work with the same person_id returns one current-employer address or null. It costs 1 record per call, even when it finds nothing.

Step 4: Read the status before you send

The status says how far to trust the address. verified was tested. catch_all_valid means we confirmed the mailbox on a domain that accepts everything. catch_all means the domain accepts everything and the mailbox is unproven.

curl -s https://api.leadocean.io/v1/people/enrich \
  -H "x-api-key: $LEADOCEAN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"person_id": "PERSON_ID_FROM_STEP_2", "reveal_email": true}' \
  | jq -r '.data.contact_data
    | select(.email_status | IN("verified","catch_all_valid","catch_all"))
    | .contact_emails[0].email'

Empty output means the status failed the filter. LeadOcean gives no refund for bounced emails, so this check is your only protection. Treat catch_all as sendable at low volume, not as proof.

Step 5: Fall back to a name pattern

When the data holds no address, build candidates from the manager's name and the company domain. Large manufacturers and retailers, where most Supply Chain Managers work, tend to use a strict shape. Pick the one you can confirm from a known address at the same company.

first="jane"; last="doe"; domain="acme.com"
printf '%s\n' "$first.$last@$domain" "${first:0:1}$last@$domain" "$first@$domain" "${first:0:1}.$last@$domain"

Never send to a candidate you have not verified. Run each one through an email verifier you trust first. A domain that accepts all mail cannot confirm a single mailbox, so a guess there stays a guess.

What you get

Step 1 is free. We ran it on 2026-10-21 for each sales region with leadocean_count_leads. The counts are mailable Supply Chain Managers (verified, catch_all_valid or catch_all, the tool default), not every one we hold. The filter is title Supply Chain Manager with job level Manager. Titles match as keywords, so read a sample before you send.

NORAM spans 5,714 employers. The gap between the two columns is people we hold without a sendable address. In APAC, manufacturing, electronics, pharma and chemicals lead the industry breakdown. A revealed person comes back in the shape below. This is the response shape from the API reference, with placeholder values.

{
  "success": true,
  "data": {
    "profile_data": { "...": "name, title, company" },
    "contact_data": {
      "has_email": true,
      "email_status": "verified",
      "email_type": "work",
      "contact_emails": [
        { "email": "jane.doe@acme.com", "type": "work", "status": "verified" }
      ]
    }
  }
}
