The problem

Sound familiar?

1

My email platform bill just doubled because we crossed a subscriber threshold.

2

I need advanced automations to manage my growing list, but they're locked behind a plan that costs $300/mo.

3

I hesitate to run list-growth campaigns because I know it just makes my software more expensive.
