MailerLite vs Sender, answered

Is MailerLite or Sender better for an online course?
Neither is better outright, and anyone who says so is guessing on your behalf. Sender if you are a list already in the thousands. Sender if you are worried about being locked in. MailerLite if you are selling the course from the same tool.
Which of MailerLite and Sender has the better free plan?
Sender allows more free subscribers (2,500 against 250). A bigger allowance is not automatically the better plan: check the welcome sequence row above, because that is where the two usually part company.
Can I move from MailerLite to Sender later?
Yes, and you should assume you will. Export your list before you cancel anything, and keep whatever marks who bought from you. We wrote the whole running order up separately.
