How it works

Set up in minutes, not days

Most email platforms require hours of configuration. Sequenzy uses AI to handle the heavy lifting so you can focus on your product.

01

Tell AI what you need

“Welcome sequence for new signups,” “re-engagement campaign for churned users,” or “draft a product update email.” Plain English, no templates to configure.

02

AI generates everything

Sequences with send delays and triggers, email copy with subject lines, audience segments — AI drafts it all. Review and edit anything before going live.

03

Launch and track

Connect your domain and go live. Sequenzy handles delivery, open/click tracking, and revenue attribution. Monitor everything from one dashboard.

Why Sequenzy

“I've built multiple SaaS products. Every time, the same story: trials expire, payments fail silently, users churn before you notice. The fix is always email. But traditional tools weren't built for SaaS.”

Mailchimp wants you to sell merch. ConvertKit is for newsletters. Klaviyo is for e-commerce. None of them understand MRR, churn, or why a failed payment at 2am needs immediate action.

So I built Sequenzy. It connects directly to Stripe, knows your subscription lifecycle, and triggers the right emails automatically. No complex automations to configure.
