This is a really powerful tool, but only when used correctly. No-one wants to receive lots of spam mail, so it’s important to communicate only when you have something worth saying. Keeping in touch with your customers is simple with email and there are many elements of best practice which we can help you with, like developing the best subject lines and making your email marketing campaign look professional.
Email too often and suffer reduced open and click rates, don't email often enough and your customers start to forget you. Consistency is key - your customers like you and your products, that's why they sign up for your e-newsletter in the first place, so be careful to provide just what they are looking for.
