I will create an Email Marketing campaign by using mailchimp and also by using the A/B Testing where we use 2 versions of the same email with changing 1 element like the photo for example and after sending it we see the results and which one converted to leads more.
Email segmentation is a very important factor to take into consideration because based on the product or service you offer we need to know for example which gender or which age is suitable for what your business is offering.
