# Choose the best email-sending package If you currently send email, we suggest averaging the number of messages you sent for each of the past three months and choosing a plan that includes at least that amount. You can upgrade or downgrade at any time. Learn more about the [differences between Starter and Premier plans](https://support.sparkpost.com/docs/faq/difference-between-starter-and-premier). If you are developing a new app that doesn’t currently send email, we suggest starting with a free account and upgrading as your volume grows. If you are interested in the enhanced services included with our Premium or Enterprise plans, please contact our team—we’d be happy to help you choose the option that best fits your needs. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
