Plauti builds native data-quality applications that run entirely within your CRM environment. No data is sent to external servers or third-party processing services, and there’s no parallel infrastructure to maintain. Your data stays where it belongs: under your control, behind your security perimeter, governed by your own access model.
For Salesforce, Plauti addresses the full lifecycle of data quality:
> Prevention at entry: Real-time duplicate detection alerts users as they type, blocking bad data before it’s created.
> Detection from external sources: Identify duplicates coming from integrations, imports, and APIs, so data quality doesn’t degrade over time.
> Batch remediation at scale: Run powerful batch jobs to find, review, and merge existing duplicates, with full audit trails for compliance and governance.
> Contact data verification: Validate email addresses and phone numbers before they’re saved to reduce bounces and failed outreach.
All processing runs natively on Salesforce infrastructure. Plauti respects your existing profiles, roles, and permission sets, so there’s no separate login, no data synchronization layer, and no new security surface to harden.
For Microsoft Dynamics 365, Plauti provides similar control over duplicates with real-time alerts, API-driven detection, batch processing, and cross-entity matching. It’s designed for CRM admins and data stewards who need direct, immediate control over data quality without waiting on developers, external consultants, or long IT ticket queues.

Sealch
Sealch is an email verification tool that performs live SMTP and catch-all checks akin to services like ZeroBounce and NeverBounce, but at an impressive rate of just $0.35 per 1,000 verifications, making it nearly ten times less expensive. Users can easily upload a CSV file or utilize the bulk API, ensuring that each email address is verified in real-time against the corresponding mail server without sending any emails. The results are presented in a clear format, categorizing addresses into deliverable, risky, and invalid, while catch-all domains are accurately marked as "risky" rather than misleadingly labeled "valid." You won't incur charges for unknown addresses, and your credits remain valid indefinitely. Designed specifically for email marketing and outbound teams, Sealch ensures that you have a reliable list ready for campaigns without the burden of high enterprise costs. Additional features include live SMTP checks, detection of catch-all and disposable addresses, filtering of role-based email addresses, bulk CSV handling, and a REST API.
