“A/B testing stands for ‘Always Be Testing,’ right? It should! Once you start testing various elements of your marketing campaigns – from PPC text ads to landing pages to email subject lines – you realize ‘A/B testing best practices’ are only a rough guideline. You never know what’s going to work with your audience until you A/B test it.”

It doesn’t have to be perfect, or go exactly as planned, but split testing your emails is essential to developing a comprehensive knowledge of your audience. In addition to testing different email factors, you should be doing this fairly regularly to maximize your results.
