Understanding how to actively engage with you customers through different channels that they are active on, can help your business enter a high level of retention. When it comes to increasing customer retention, you should consider the following factors. Always reward your customers who have been with your brand for a while by showing that you care and value their business. Personalize your customer's experience (from the very first visit to your site). Email marketing is really useful for post-purchase customers. After your customer has purchased from your site this is a good time to follow up with them and maybe offer them some other suggestions based on their purchase. Email marketing can also be used to wish your customers happy birthday and can be a very effective retention tactic or just send them a reminder email if they haven't purchased for a while. Good luck!
