Write down the three things your newsletter platform must do. If they are publish an issue, manage your list and send reliably, a simpler tool deserves a closer look. If they include selling memberships or running a referral engine, price is only part of the decision.
Our recommendation is conditional: consider MailCheap when its publishing workflow meets your requirements. Compare the subscription cost with the time and revenue involved in replacing features you already use. A lower bill is useful only if the trade-off works for you.
