Email lead lifecycle nurturing + contract renewal notifications for SaaS clients with app and web users?
Working on a stack design for a SaaS client that's currently a mess — no lifecycle tracking, nurturing is manual emails, and contract renewals are calendar reminders in someone's inbox. Classic early-stage chaos
What they need:
- Lead nurturing sequences for new contacts
- Lifecycle stage tracking (Lead → Trial → Active → At-Risk → Churned)
- Automated renewal notifications via email AND push (mobile app + web app
What I'm proposing:
HubSpot for the CRM layer — contact records, lifecycle stages, and renewal trigger logic Customer io for execution — email sequences, push notifications, and in-app messages.
HubSpot owns the *who and when*. Customer io fowns the *what and how
However this tech stack is expensive since I cannot automate the lifecycle stage without a Pro license.....
Why I'm second-guessing myself: Maybe activecampaign or Brevo is a good option?
HubSpot Marketing Hub can do email on its own, but can't handle push notifications or deep behavioral triggers for app users. Customer io solves that — but now I'm managing a sync between two systems.
Anyone run this combo in production? What broke, what worked, and is there a better approach I'm missing?
