Tool insights
MailCheap lets newsletter writers send issues from their own domain and pay for the emails they send, not for how many people are on the list. A growing list that is mailed rarely therefore does not push the bill up on its own.
Many newsletter tools charge by subscriber count, so costs climb as a list grows, even when few emails go out. MailCheap ties the price to sending volume instead.
Newsletter writers and creators who run paid newsletters, especially those moving from beehiiv, Substack or Mailchimp. People who want a free plan or a trial period should look elsewhere.
What it does
MailCheap is a web-based service for writing and sending email newsletters. Its main difference is the billing unit: you pay for the number of emails sent, not for the number of subscribers. It is made by Marc Lou's company, JustShipIt Pte. Ltd. You write an issue in a campaign editor, schedule it, and send it from your own domain.
