The goal of any marketer is to optimize the performance of their campaign for maximum impact and reach. A/B testing allows marketers to test elements of their marketing materials and better understand audience preferences. A/B tests are performed to determine if any one element changes the result of a campaign.
Email Marketing

A/B testing is especially helpful in email marketing since there are so many tools available to monitor open and click-through rates. Data management sites like HubSpot allow marketers to collect user interaction data that can be used to run analyses. This information helps digital marketers design better promotional materials that engage audiences.
Decision Making
A/B testing can also help marketers make decisions. Often the results of an A/B test determine investment priorities for organizations. If an element change in a campaign does not bring a significant increase in uptake, it may not be worth investing the time and money to fully implement the change.
A/B testing is a very simple yet effective way to develop effective marketing materials. Therefore, marketers should employ A/B tests when deciding whether to change an element of a campaign before investing time and money. Using A/B testing can help marketers optimize their campaigns for success.
