Module 03 · Get contact details

Outcome: a verified work email for a profile, and a clear rule for when a 12-credit phone number is worth buying.

Tools in this module

Tool	Cost	Required input	Use it when
`verify_email`	0.3	`email`	Always, before sending
`enrich_person`	1	Any one identifier	You have a name, email, URL or company and want the record
`find_work_email`	1	`linkedin_url`	The default contact tool
`find_personal_email`	3	`linkedin_url`	Work address bounced, or they are between jobs
`validate_whatsapp`	1	`mobile`	Before a WhatsApp touch
`find_mobile_number`	12	`linkedin_url`	Late-stage, named accounts only
`find_work_phone`	12	`linkedin_url`	Late-stage, named accounts only

Read that table top to bottom. It is also the order you should run them in — cheapest first, and each step decides whether the next one fires.

The two phone tools are 12 credits each, 40× the cost of a verification. Never run them across a list. Run them on a named account after an email has already failed.

Example prompts

find_work_email — the default


Use find_work_email with:
- linkedin_url "https://linkedin.com/in/janedoe"
- first_name "Jane"
- last_name "Doe"
- organization_name "Stripe"

Do not guess an email pattern. If nothing comes back, say so and stop.

The optional name and company fields are not decoration — they disambiguate common names and lift the hit rate on the same 1 credit.

verify_email — always


Use verify_email on "jane.doe@stripe.com" and tell me the deliverability
status. If it is not deliverable, do not use it.

enrich_person — when you have something other than a URL

Any one of first_name + last_name, email, linkedin_url, or organization_name is enough. More identifiers, better match.


Use enrich_person with first_name "Jane", last_name "Doe",
organization_name "Stripe". Return title, company, location and
linkedin_url.

find_personal_email — the fallback


Use find_personal_email with linkedin_url
"https://linkedin.com/in/janedoe", organization_name "Stripe".

Only run this because the work email came back undeliverable.

find_mobile_number — 12 credits, one person


Use find_mobile_number with linkedin_url
"https://linkedin.com/in/janedoe", first_name "Jane", last_name "Doe",
organization_name "Stripe".

This is one person only. Do not run it on any other row.

find_work_phone — 12 credits, one person


Use find_work_phone with linkedin_url
"https://linkedin.com/in/janedoe", organization_name "Stripe".
Return the number and extension if there is one. One person only.

validate_whatsapp — before the touch


Use validate_whatsapp with mobile "+14155552671".
Include the country code. Tell me yes or no.

The chain that costs ~2.3 credits

Find the email

find_work_email on the LinkedIn URL — 1 credit.

Verify it

verify_email on whatever came back — 0.3 credits. Undeliverable stops the row.

Fill the record

linkedin_profile_enrich or enrich_person for title, company and history — 1 credit.

Stop

Phones only if the email failed and the account is worth 12 credits.

Run it as one message:


For this profile: https://linkedin.com/in/janedoe

1. find_work_email — pass organization_name "Stripe".
2. verify_email on the result. If undeliverable, stop and tell me.
3. enrich_person to fill in title and company.

Return one row: name, title, company, email, verification status.
Report credits used.

Workflow prompts

This is the module that plugs into everything else. SyncGTM finds and verifies; your CRM or sequencer holds the result.

HubSpot — fill the contacts missing an email

pull all contacts missing emails
use SyncGTM MCP to find work emails
verify before writing
update the records in HubSpot


1. Pull every HubSpot contact with an empty email that has a LinkedIn URL
   on the record. Tell me how many there are before doing anything else.
2. For the first 50: find_work_email using the LinkedIn URL, passing
   first_name, last_name and the company name from the record.
   Do not guess an email pattern.
3. verify_email on every result. Drop anything undeliverable — do not write it.
4. Show me the table: contact, LinkedIn, found email, status. Wait for my go.
5. On my go-ahead, update each HubSpot contact with the verified address and
   set a note with the verification status and today's date.
   Never overwrite an email that already exists.

Swap HubSpot for Salesforce, Attio or Close — the shape does not change, only the system that holds the record.

Attio — repair records that have decayed

find contacts whose title or company looks stale
re-enrich the person from their LinkedIn profile
review the diff, write only what changed


1. Pull Attio people records not updated in 12 months that have a LinkedIn URL.
2. For each: enrich_person with the LinkedIn URL to get current title
   and company.
3. Compare against what Attio holds. Build a diff table: field, old value,
   new value. Only include rows where something actually changed.
4. Show me the diff. Do not write anything yet.
5. On my go-ahead, update only the changed fields. Leave everything else alone.

Instantly — verify a list before it touches a campaign

take the list about to be sequenced
verify every address
load only the deliverable ones


1. Take this list of email addresses.
2. verify_email on each — 0.3 credits, so <N> addresses is about <N × 0.3>.
   Confirm the total with me before starting.
3. Split into three groups: deliverable, undeliverable, accept-all/risky.
4. Add ONLY the deliverable group to the Instantly campaign "Q3 RevOps".
5. Give me the undeliverable and risky lists separately so I can decide
   what to do with them.

Escalate to a phone, one person at a time

confirm the email path has failed
name the account
buy exactly one number


This is for ONE person: <LinkedIn URL>. Their work email came back
undeliverable and this is a named target account.

1. find_personal_email first — 3 credits. If that works, stop there.
2. Only if it returns nothing, find_mobile_number — 12 credits.
3. If a mobile comes back, validate_whatsapp on it with the country code.

Do not run any of this on anyone else. Report exactly what was spent.

Best prompting practices

Pass the optional fields. first_name, last_name and organization_name cost nothing and raise the hit rate.
Say “do not guess.” A model with no result will happily invent first.last@domain.com. Undeliverable addresses hurt your sending domain.
Verify before you send, not before you store. 0.3 credits is the cheapest insurance on the server.
Gate the expensive tools in the prompt. “Only if the email failed” is a condition the model will honour if you write it.
Include the country code for validate_whatsapp — +14155552671, not 4155552671.

Where this breaks

“Get me everyone’s phone number” against a 40-row list is 480 credits and the model will run it. State the row count and the tool in the same sentence, every time.

Waterfall tools only bill when a provider returns a result, so a run on a well-known segment costs less than the same run on a long tail. Budget on hit rate, not on row count.

Further automation

MCP Contact Enricher is this module as a skill file — /mcp-contact-enricher runs the stack cheapest-first and keeps the 12-credit phone tools behind an explicit yes.

Contact Finder goes further: a company list in, verified decision-maker contacts out.
