Mailchimp vs MassMailer: Which is best for you?

Mailchimp allows us to quickly create, automate, and analyze email campaigns, making it an excellent choice for both beginners and seasoned marketers.

For agencies, they forced that the pre-paid credits expire in a year, and the list plans aren't worth the money unless you send a lot of frequent mails. If you send campaings from time to time to different customers, unless your volume is huge, fees make it unpayable. If you are an end user, then the story is different and prices will make more sense (maybe that's their idea of customers right now).

MassMailer is a solid, dependable solution for Salesforce-centric teams that need powerful bulk email capabilities without the complexity or cost of a full marketing automation platform.

Some drawbacks include occasional deliverability issues and some advanced customization options are limited.
