Why Sequenzy Beats MailerLite for SaaS

At nearly identical pricing ($49 vs $47), the choice comes down to features:

Native Stripe integration

Stripe integration handles subscription lifecycle automatically. MailerLite doesn't natively understand SaaS billing events like trial expiration, payment failure, or plan upgrades.

Transactional email included

MailerLite requires its sister product MailerSend for transactional email. Sequenzy includes both marketing and transactional from one platform.

AI-generated sequences

Describe what you want and Sequenzy creates entire email sequences. MailerLite's automation requires manual setup.
