USE CASE:
Collecting replies and bounces from every outreach tool
Everything below is about collecting replies and bounces from every outreach tool, and about which reply tracking method holds up on a list rather than one record. Mamba Labs writes Apify actors for this kind of work, and Sequencer Event Poller is the one aimed at reply tracking.

Where this starts
Email runs in Instantly, LinkedIn runs in HeyReach, and an older campaign still sits in lemlist. Replies, bounces and booked meetings land in three inboxes and three dashboards. Nobody can say how many people replied this week without opening all of them. Reporting and CRM updates wait on whoever has time to copy it across.
Traditional Search Tools
- Native CRM integrations. Most sequencers push events to HubSpot or Salesforce. Each integration maps fields differently, so the merged view still needs cleaning.
- Zapier or Make. One zap per tool per event type gets you there. It breaks quietly when a tool changes its payload, and the task count grows with volume.
- Export from each tool weekly. Download each tool's activity export and merge them in a sheet. It works and it is always a week behind. Unsubscribes that miss the merge get emailed again.
