Issues with Building Flows and Lemlist Integration

Same here! Having issues building out flows, very slow and barely responsive. Lemlist integration isn’t working either, can’t push leads to campaign.

For slow performance, try a hard refresh: Mac: Command + Shift + R (Chrome/Firefox) or Option + Command + E (Safari). Windows: Ctrl + F5 or Ctrl + Shift + R. For Lemlist integration issues, ensure you have: 1. A campaign already set up in Lemlist 2. Your Lemlist API key connected (found in Lemlist Settings → Integrations) 3. The correct Campaign ID when adding leads If enrichments aren't running, click the column header, hover over "Run column," and select "Force" to jumpstart the process.

Hey, Kain D. Reduce Automation Load Turn off real-time automations while building. Use manual "Run Row" to test. Break Large Tables Split heavy tables into smaller ones. Use linked tables for enrichment. Clear Cache + Restart Browser Clay gets sluggish with long sessions. Refresh everything. Lemlist Integration Fix Re-authenticate Lemlist in Clay Go to Integrations remove & re-add Lemlist. Use correct workspace API key from Lemlist (Settings API). Check Campaign Format Lemlist only accepts contacts with valid email + first name. Campaign must exist in Lemlist first. Use Delay Step Add a Delay 1s step before pushing to Lemlist sometimes instant push fails due to rate limits.

Thanks for sharing those helpful tips! You're absolutely right about these optimization strategies. For performance issues, hard refresh is key: Mac: Command + Shift + R (Chrome/Firefox) or Option + Command + E (Safari). Windows: Ctrl + F5 or Ctrl + Shift + R. For Lemlist integration, you need your API key from Lemlist Settings → Integrations, and the campaign must already exist in Lemlist before adding leads. The integration requires a Campaign ID and accepts inputs like Email Address, Name, Phone Number, and more. If enrichments aren't running, click the column header, hover over "Run column," and select "Force" to jumpstart the process. Your suggestions about breaking large tables, using manual testing, and adding delay steps are excellent workflow optimizations!
