Overview
MailUp and Mailchimp are both popular email marketing platforms with very different pricing models. For our take on each, see our MailUp comparison and Mailchimp comparison.
MailUp's Contact Advantage
MailUp's unlimited contacts model is its biggest differentiator. At ~$47/month, you can have as many contacts as you want. Mailchimp charges $100/month for 10K contacts and prices climb fast from there. For businesses with large but modestly active lists, MailUp is dramatically cheaper.
Mailchimp's Ecosystem
Mailchimp integrates with 300+ tools and is supported by virtually every SaaS platform, CMS, and e-commerce tool. MailUp has fewer native integrations. If your stack depends on third-party connections, Mailchimp's network effect is real and hard to replicate.
The Sequenzy Alternative
For SaaS founders who don't need unlimited contacts or massive integrations, Sequenzy combines transactional email and marketing campaigns with Stripe integration at $49/month.
