Mailchimp suits people who need email campaigns alongside automation, segmentation, landing pages, or A/B testing. Its free plan may fit smaller contact lists and modest monthly sending needs.
Posthawk suits developers and teams sending several kinds of email through code, APIs, or SMTP. Teams that want to run delivery infrastructure themselves can deploy it with Docker Compose.
