The Real Problem

The List Can Get Scattered

A SaaS company may collect emails in more than one place. Some people join from waitlists, product forms, trial signups, changelog links, webinars, and launch pages. If the list is scattered, the next step is easy to miss.

People Join For Different Reasons

One person may want a waitlist, trial, product update, webinar, or onboarding path. Another may only want regular updates. They should not always get the same email.

Follow-Up Slips Away

A good signup is only useful if the next email arrives at the right time.

Growth Can Make The Tool Feel Costly

A free resource, launch, or busy month can grow the list before it brings in steady revenue.

Before You Start

What SaaS Companies Should Decide First

Common Mistakes
