# Contact Verification Workflow

Publisher: Altss LLCPublished 2026-01-21Content modified 2026-01-21

Systematic process for confirming that contact information (email, phone, LinkedIn) is accurate, active, and correctly associated with the intended person.

Unverified contacts waste outreach effort (bounces, wrong person, inactive) and damage reputation (emailing outdated addresses signals poor diligence and data quality).

**Expanded Definition**

Verification workflow includes: email validation (syntax check, domain verification, bounce testing), phone validation (area code consistency, number format, carrier lookup), LinkedIn confirmation (profile currency, employment verification, activity signals), cross-channel consistency (same person across email/phone/LinkedIn), and engagement testing (response to low-stakes touchpoint).

Verification frequency varies by contact importance and decay rate: high-value targets warrant re-verification every 6-12 months; routine contacts accept 12-24 month cycles. Automated verification (syntax, format checks) runs continuously; manual verification (profile review, engagement testing) triggered by importance or age thresholds.

**Signals & Evidence**

Verification quality indicators:

- **Email validation**: Syntax correct, domain active, no bounce on test send, appears in recent communications

- **Phone validation**: Format matches region, area code consistent with location, number not disconnected

- **LinkedIn verification**: Profile updated recently, current employer matches, active engagement (posts, comments)

- **Cross-channel consistency**: Name, employer, location match across email domain, phone area code, LinkedIn

- **Engagement signals**: Response to communications, LinkedIn profile views, email open rates

**Decision Framework**

- **Verification depth**: High-value targets = full manual verification; routine contacts = automated validation

- **Re-verification triggers**: Role changes, firm transitions, communication bounces, >12 months since last verification

- **Failed verification response**: Remove inactive contacts from active lists; research updated information before re-adding

**Common Misconceptions**

*"Email syntax = valid email"* → Syntax check doesn't confirm address is active or monitored; bounce testing required. *"LinkedIn profile = current contact"* → Many maintain profiles but don't check messages; verify through recent activity signals. *"Once verified = always accurate"* → Contacts decay (6-12 month average); regular re-verification required.

**Key Takeaways**

- Contact verification combines email validation, phone checking, LinkedIn review, and cross-channel consistency—not just email syntax

- Verification frequency should match contact importance and decay rate (high-value = 6-12 months; routine = 12-24 months)

- Failed verification triggers research for updated information rather than repeated contact attempts to outdated channels
