WHY VALIDATE YOUR CONTACTS?

The Foundation of Every Successful Campaign

Cut bounce rates: Catch invalid, misspelled, and non-existent email addresses before they ever leave your list.

Protect sender reputation: Reduce spam-trap hits and hard bounces that put your domain's deliverability at risk.

Validate entire groups instantly: Run a full group scan and watch progress update live, right down to error and completion status.

Remove duplicates automatically: Every group is de-duplicated down to unique, addressable contacts.

Stay compliant: Keep your database accurate and audit-ready for data-protection and anti-spam regulations.

WHAT DOES VALIDATION CHECK?

Four Checks, One Clean Contact List

Every contact is run through a layered set of checks before it's marked valid, so your teams only ever send to addresses that are real and reachable.

Syntax & Format Check

Flags malformed emails and numbers instantly—missing @, bad domains, or incorrect country codes.

Domain & MX Lookup

Confirms the domain exists and is actively configured to receive mail before it's counted as valid.

Mailbox & Carrier Verification

Pings the mailbox or carrier directly to confirm it's active, without ever sending a real message.

Disposable & Role Detection

Flags throwaway domains and generic role addresses like info@ or admin@ that rarely convert.

BUILT FOR SCALE

From Single Contacts to Million-Row Lists

Plumb5's validation engine handles a single new sign-up the same way it handles a bulk import, so your data stays clean no matter how it enters your CRM.

Group & Bulk Validation: Validate any contact group—All Contacts, Customers, or a custom segment—in a single run.

Live Progress Tracking: Watch each validation move from queued to in-progress to completed, with time-taken logged automatically.

Point-of-Entry Validation: Check new contacts the instant they're captured on forms, signup flows, or API calls.

Error Reporting: See exactly which records failed and why, so lists can be corrected instead of discarded.

Scheduled Re-Validation: Automatically re-check existing groups on a recurring basis to catch contacts that have gone stale.
