Email Verification & Deliverability
iPaaS Automations versus Direct Integrations
Published: 12/4/2025
For businesses using CRMs and marketing platforms such as HubSpot, Drip, AWeber, Salesforce, connecting external services like Impressionwise email verification and threat removal can be done either via direct integration or through an iPaaS (Integration Platform as a Service) workflow like Make.com, Integrately, or Zapier. At Impressionwise, we strongly recommend iPaaS workflow automations for most use cases. Here’s why. Flexibility Across Multiple PlatformsDirect integrations often require a native app or custom API connection for each platform. For example: HubSpot, Salesforce, and Drip all have different APIs, data structures, and limitations. With iPaaS workflows:
This level of cross-platform orchestration would require separate custom integrations for each CRM if done directly. Rapid Deployment and No-Code SetupDirect integrations often require developer resources to implement, maintain, and update when APIs change. With iPaaS workflows:
Scalability and Bulk ProcessingWhile direct integrations are often optimized for real-time single-event triggers, iPaaS platforms excel in batch processing:
This aligns perfectly with Impressionwise’s mission to maintain data quality at scale, preventing email delivery issues before they occur. Reduced Maintenance BurdenAPIs change frequently. Maintaining direct integrations across multiple platforms can be time-consuming and error-prone. iPaaS providers like Make.com or Integrately handle much of this automatically:
This means less downtime, fewer failed workflows, and a more reliable automation system for clients. Cost Efficiency and Faster ROIBuilding and maintaining direct integrations for each platform can be expensive. iPaaS platforms:
Practical Impressionwise Use Cases with iPaaSScenario 1: New Lead Verification in HubSpot
Scenario 2: Bulk List Verification Across Platforms
Scenario 3: Multi-System Orchestration
All of these scenarios can be accomplished without coding, with one unified automation platform. Why Impressionwise Prefers iPaaS
Final ThoughtsWhile direct integrations can provide real-time, platform-specific functionality, iPaaS workflow automations offer flexibility, speed, scalability, and multi-system orchestration—making them the preferred approach for Impressionwise clients. By leveraging iPaaS platforms like Make.com or Integrately, businesses can automate email verification, threat removal, and data hygiene across all their marketing and CRM systems efficiently and reliably, without needing heavy development resources.
