Overview
MailUp and Kit (formerly ConvertKit) serve entirely different audiences. For our take on each, see our MailUp comparison and Kit comparison.
Kit for Creators
Kit is purpose-built for creators. Paid newsletter subscriptions, digital product sales, a creator network for cross-promotion, and a sponsor marketplace. MailUp has none of these. If you're building an audience and monetizing content, Kit has the ecosystem.
MailUp for Business Volume
MailUp's strength is unlimited contacts with the BEE editor and SMS. For businesses sending campaigns to large lists with professional design needs, MailUp is the practical choice at half the price of Kit's paid plans.
The Sequenzy Alternative
For SaaS founders who don't need creator features or unlimited contacts, Sequenzy combines transactional email and marketing campaigns with Stripe integration at $49/month.
