What we learned using email to personalize NPS customer feedback

Last week we sent out our annual survey. Every spring we ask our paying, active customers if they would recommend MailerLite to their friends. This is how we measure our Net Promoter Score (NPS) and get new feedback about the product.

During the survey, I received some emails like the one below from people who are interested in conducting their own surveys and curious how we set up ours. I wrote this blog post to share how we survey our customers and what we have learned through the process.
