Looking for a cheaper alternative to Mailchimp

I don’t know about you, but I find Mailchimp too pricey for my budget. $45 a month is a lot of money for a newsletter service. Do you have any suggestions for a more affordable option? I came across an article about some alternatives, and I’m looking into ConvertKit, Drip, and MailerLite, but I’m not sure which one is the best. Some people say ConvertKit works well with Kajabi, but I don’t know what that means.

Sorry for complaining, but I have so many other expenses besides Mailchimp. I hope I can find a better alternative. Thank you.
