Elastic Email and Mailshake are two online email marketing solutions. While both solutions offer a range of email automation and marketing features, they differ in how they are priced and the types of users that they target. Elastic Email provides a pay-as-you-go plan with a free trial, while Mailshake offers a free plan and monthly plans that are ideal for larger teams. This makes Elastic Email more suitable for smaller businesses looking to dip their toes into email marketing, while Mailshake is better suited for larger teams and businesses that are conducting more detailed campaigns. Additionally, Mailshake has additional features such as A/B testing, tracking, and analytics, which give users more control over their campaigns.
