Omnisend Omnichannel Email Validation Troubleshooting Guide

Common Omnisend Integration Issues

Issue: Cross-channel validation data not syncing properly
Solution: Verify API permissions for all channels (email, SMS, push). Ensure webhook endpoints are configured for each channel type.
Issue: Channel preference optimization not working
Solution: Check that validation data includes channel capability flags. Verify AI optimization model has sufficient historical data (minimum 30 days).
Issue: Unified customer profiles showing incomplete data
Solution: Ensure all channel APIs are properly connected. Implement data backfill for existing customers to complete profiles.

Multichannel Validation Performance Issues

Issue: High API usage from multichannel validation calls
Solution: Implement intelligent caching for validation results. Use batch processing for bulk operations and progressive validation for new contacts.
Issue: SMS validation causing delays in email campaigns
Solution: Run multichannel validation asynchronously. Use parallel processing and set appropriate timeout limits for each validation type.

Omnichannel Analytics & Attribution Issues

Issue: Cross-channel attribution not showing validation impact
Solution: Set up custom tracking parameters for validation events. Use UTM parameters and conversion pixels to track validation correlation with performance.
Issue: Journey analytics not updating with validation changes
Solution: Implement real-time data streaming for validation updates. Ensure journey tracking includes validation state changes as trigger events.
