Mailchimp is a solid choice for any small business getting started with email marketing. It’s got solid integrations and a really friendly price to allow you to start building an audience and communicating with your subscribers without a steep initial time or financial investment. Unfortunately, given how easy Mailchimp is to get started with, many businesses and users dive in and grow their list size, but begin to see their engagement start to shrink and get in over their heads without a proper understanding of how to manage their list hygiene and deliverability.
