Melissa
Melissa (formerly Melissa Data) verifies emails, phone numbers, and postal addresses. The address validation is the standout: global coverage with postal authority data. I use it when a team needs to clean addresses for shipping or compliance, not just dedup. The email and phone verification are fine but not the main reason to use it.
Why it ranks here
- Global address validation with postal authority data
- Multi-field verification (email, phone, address)
- Strong for compliance and shipping use cases
Where it sits
- Global address validation and postal authority data exceed BriteVerify and NeverBounce's email-only focus
- BriteVerify processes email verification faster and integrates more tightly with Salesforce
- Address compliance capabilities unmatched when shipping or regulatory requirements demand validated addresses
How GTM Systems teams use it
- Address validation for Accounts and Contacts with global offices
- Pre-shipping data cleanup to reduce undeliverable mail
- Phone number formatting and validation for outbound teams
- Compliance workflows that require verified addresses
In-depth notes
- Priced per verification with tiered plans by volume
- API, batch, and Salesforce integration options
- The address validation is expensive but accurate
- I use it when address quality is critical, not just email
Best for
Teams with global operations that need address and phone validation, not just email
Avoid if
You only need email verification (BriteVerify or NeverBounce is simpler and cheaper)

Setup
Create a Melissa account and obtain API credentials for address, phone, and email verification. Configure Salesforce integration or API endpoints for batch processing. Define validation rules for each field type.
First thing to build
Export all Accounts and Contacts with addresses from Salesforce, upload to Melissa for batch address verification, then import the standardized and validated addresses back with delivery confidence scores.
What actually matters
- Global address validation: postal authority data for 240+ countries
- Phone formatting: E.164 international standard or local formats
- Email verification: syntax, domain, and mailbox checks
- Result handling: confidence scores, correction suggestions, and undeliverable flags
Watch out
Address validation is expensive per record; prioritize high-value Accounts and recent records to control costs.
