Performance marketers
You're running outreach campaigns across multiple lists but your tracking sheet only updates when someone manually checks replies, so the response counts you're optimising against are always a few hours behind — with this integration, every campaign reply triggers instant delivery updates and your data stays current.
Outbound sales representatives
You need to act fast when prospects reply to your outreach, and you find out too late because notifications sit in unread folders — with this integration, every interested response instantly dispatches an email via SMTP and alerts your team so you can close deals faster.
📊
Agency account managers
You answer to clients who want to see campaign progress reports in real time, but compiling delivery metrics takes hours of manual copy-pasting — with this integration, every campaign event updates your logs automatically and your client dashboards remain perfectly accurate.
📨
Email campaign operators
The volume of outbound sends is too high for anyone to keep up by hand when bounces and unsubscribe requests pile up across lists — with this integration, every delivery failure and unsubscribe event is handled instantly without manual spreadsheet sorting.
🤝
RevOps specialists
You own the handoff between campaign execution and CRM updates, depending on upstream teams to forward lead details before you can process them — with this integration, every interested reply flows straight into your CRM and email systems without manual friction.
🔍
Deliverability engineers
You need a reliable history of campaign bounces and failures, but keep finding gaps in your logs due to manual tracking oversights — with this integration, every delivery error is captured in your sheets and messaging channels automatically.
