MailerLite is the most popular alternative to Mailchimp for small businesses that find Mailchimp too expensive or too cluttered. The interface is clean, the free plan covers 500 contacts and 12,000 monthly emails, and the entry paid tier is among the cheapest in the category.
Growing Business adds basic automation and the Advanced plan unlocks advanced workflows, A/B testing, and a custom HTML editor. SMS is only available through third-party integrations, which is a limitation for businesses that want a single platform for email and SMS.
MailerLite was founded in 2010 and is headquartered in Vilnius, Lithuania.
