We collaborate closely with you to ensure that your email providers refrain from delivering spam to your inbox. Within just a few weeks, our clients have reported their open rates skyrocketing to more than double! Recipients who are highly engaged tend to open emails and actively scroll through the content as they read. This engagement should occur for nearly all opened emails, provided that the information is concise enough to fit within a single page. When a recipient retrieves an email from the spam folder, it indicates to the inbox provider that they believe an error has occurred. Furthermore, if someone shifts an email from the promotions tab to the primary inbox, it signals to the provider that their sorting method may not align with user preferences. Such actions suggest that those emails, along with others like them, should be directed straight to the main inbox. This behavior demonstrates genuine interest in the content of the email, leading inbox providers to interpret it as "This message is of utmost importance; please ensure it is not categorized as spam." As a result, building a positive relationship with your email recipients can significantly enhance your overall engagement rates.

Plauti is a data quality platform built natively for CRM, designed for organizations that want tight governance, strong security, and practical control over the accuracy of their customer data. Unlike solutions that move data to external servers or require separate platforms, Plauti runs entirely inside your existing CRM infrastructure, so no data leaves your system and no additional security perimeter is introduced. For Salesforce customers, Plauti covers the end-to-end data quality lifecycle: Prevent duplicates at the source: Real-time alerts notify users of potential duplicates as they enter records, helping sales, marketing, and service teams keep data clean from the start. Protect against hidden duplicates: Detect duplicates created by imports, integrations, and APIs to keep inbound data streams aligned with your standards. Remediate at scale with batch jobs: Run configurable batch processes to find, review, and merge existing duplicates across large data volumes, with full audit trails that support compliance, internal controls, and reporting. Verify contact information: Check email addresses and phone numbers before they’re saved to reduce bounce rates, improve campaign performance, and support more reliable outreach. All of this operates on Salesforce’s own infrastructure, using your existing permissions, roles, and security model. There is no separate user login, no data sync lag to manage, and no additional compliance gap to justify to auditors or security teams. For Microsoft Dynamics 365, Plauti focuses on robust duplicate prevention and control. Admins can configure real-time alerts, leverage API-based detection, run batch processes, and apply cross-entity matching rules to keep accounts, contacts, and leads aligned and consolidated.
