Why CRM data rots

B2B contact data decays measurably each year. People change jobs. Emails bounce. Companies merge or shut down. Your CRM fills up with stale records that break routing rules and waste SDR time.

The most cost-effective way to keep your CRM clean: run background agents that check job changes daily, validate emails, and flag stale records automatically.

How to clean your CRM

Step 1: Export your contacts

Pull a segment from HubSpot, Salesforce, or Attio as a CSV. Include email, name, company, and any fields you want to validate.

Step 2: Run a pilot cleanup

Tell Claude Code

Take this CSV of 5,000 HubSpot contacts. Re-enrich via waterfall. Validate every email. Flag anyone whose job title changed. Deduplicate by email + LinkedIn URL. Start with 50 as a pilot.

Claude Code reads your Deepline skills and runs:

deepline plays search "CRM cleanup job change email validation deduplication" --json
deepline plays describe prebuilt/job-change-check --json
deepline tools search "email validation" --json
# Author crm-cleanup.play.ts to compose job-change detection, email validation,
# deterministic email + LinkedIn URL deduplication, and reviewed CRM writeback.
deepline plays check crm-cleanup.play.ts
head -n 51 crm-export.csv > pilot.csv
deepline plays run --file crm-cleanup.play.ts --csv pilot.csv --watch

Step 3: Review what Deepline flags

For each contact, the output shows:

  • Email status: valid, catch-all, or bounced
  • Job change: new title and company if detected
  • Duplicate cluster: other records that match this person

Step 4: Run the full list

Tell Claude Code
Looks good. Run the full list.

Claude Code continues:

deepline plays check crm-cleanup.play.ts
deepline plays run --file crm-cleanup.play.ts --csv crm-export.csv --watch

Step 5: Write back to CRM

Tell Claude Code
Write the cleaned data back to HubSpot.

Claude Code adds an idempotent HubSpot write stage after the review boundary, then checks and runs the same Play:

deepline plays check crm-cleanup.play.ts
deepline plays run --file crm-cleanup.play.ts --csv crm-export.csv --watch

Only changed fields update. Good data stays untouched.

Cost breakdown

Compare to bundled-platform alternatives or manual spot-checks at 40+ hours per quarter.

Who uses this

  • RevOps leads responsible for data quality
  • Ops teams running quarterly hygiene before board reporting
  • Sales managers tired of reps calling people who left 6 months ago

Deploy background agents for ongoing cleanup

Instead of quarterly manual cleanups, deploy background agents that run daily:

Tell Claude Code

Deploy this as a background agent that checks job changes daily. Send me a Slack message with a summary of changes and let me approve before writing back to HubSpot.

Claude Code declares the cron trigger in the Play:

// crm-cleanup.play.ts definePlay options
{
  cron: { schedule: '0 8 * * *', timezone: 'America/New_York' },
}

It then checks, publishes, and verifies the live version:

deepline plays check crm-cleanup.play.ts
deepline plays publish crm-cleanup.play.ts
deepline plays describe crm-cleanup --json
deepline plays versions --name crm-cleanup --json

Background agents research accounts across multiple providers, detect job changes, validate emails, and surface changes for your approval - all without manual exports.

Common questions

1Does this overwrite good data?+

No. Deepline only updates fields where it found newer information. If a field is blank in the enrichment, the original value stays.

2What CRMs are supported?+

HubSpot, Salesforce, and Attio have native integrations. For others, export/import via CSV.

3How do I handle duplicates?+

Deepline clusters them for review. You decide which record to keep.
