Mailchimp Transactional (Mandrill) Review & Pricing

How I review: I don't pretend to have used every single tool on this list (no one has). But I have used a lot of them on client projects and my own projects, and I'm still learning. If I haven't used a tool, I sign up for a test account to explore the interface, check pricing directly, and research reviews from real users.

Ratings methodology: Ratings are weighted across ease of use, automation depth, deliverability track record, integrations, pricing fairness, and support quality. No vendor can pay to improve their rating.

Affiliate links: Some links earn me a commission if you sign up. This never influences my scores or rankings. Tools are always ranked on merit first.
