What results did you see launching Klaviyo or Omnisend for the first time?

I’m interested to know what your results looked like a week, month, year after launching your email marketing platforms. I’m looking to hear from people who started with less than 500 contacts and only implement basic triggers, such as welcome, cart abandonment, we miss you etc…

I’m about to launch on Klaviyo and looking for growth inspiration and expectation setting 🙂
