📊
Data analysts and marketers
You're exporting time data and client lists from Harvest manually, but your newsletter platform updates fall hours behind schedule so your campaign targeting runs on outdated records — this integration means every new client and paid invoice syncs instantly to your subscriber lists.
⚡
Account managers and team leads
You manage client projects in Harvest and need to act fast when billing milestones occur, but newsletter unsubscriptions or paid invoices sit unnoticed until someone checks reports — with this integration, every subscriber status change triggers immediate operational visibility.
🤝
Client success teams
You answer to stakeholders who want to see project progress and active subscription counts aligned, but disjointed tools leave gaps in your client history — automating both apps means your subscriber lists and project records stay perfectly synchronized.
📈
Operations managers
The volume of billable projects and newsletter subscribers is too high for anyone to keep up by hand, leading to missed audience segments and delayed campaign updates — connecting these apps means automated subscriber additions run reliably behind the scenes.
🔄
Project coordinators
You own the client onboarding step and depend on someone upstream to hand over timesheet data before you can update newsletter lists, causing bottlenecks — this integration means every new Harvest client populates Sendy subscriber segments automatically.
🗂️
Finance and admin leads
You need a reliable audit history of paid invoices and subscriber counts, but manual data transfers keep leaving gaps in your records — automating both apps means every financial milestone accurately updates your marketing database.
