Yay, you made a sale! Apart from sending a transactional order confirmation email, it’s also very effective to follow-up with new customers after they’ve made their first purchase. Ask them whether they enjoyed your service or product, and if there’s anything that could be improved.
A first-purchase feedback email is triggered when an order is completed. It can only be sent to customers that are also available in your MailerLite subscriber list. To collect more newsletter subscribers, you can ask people during the checkout process whether they want to receive your email campaigns.
