Recommended Email Flow

Building out our email campaigns seems like the next logical step in growth for us. However, we worry about losing email domain authority / sender reputation by sending too many emails.

We have a welcome email for new customers with an offer, a follow-up email for abandoned cart customers, and a follow-up email for product reviews. What other emails should we ideally have, and how often?

  1. What do you recommend are the most important emails to have set up in Shopify Flow?
  2. And what tips do you have for ensuring a strong sender reputation?

Thanks in advance!
