# Kit (ConvertKit)
Canonical: https://automationpulse.dev/ja/tools/convertkit

A creator-focused email platform (formerly ConvertKit) built around tag-based automation and selling digital products.

Kit (formerly ConvertKit) is built for creators who sell, courses, memberships, digital downloads. Its tag-based model treats subscribers as entities flowing through sequences, and its visual automation builder is one of the most mature in the creator category.

Commerce is native: digital products, paid newsletters, and tip jars are built in. The free Newsletter plan is generous (up to ~10,000 subscribers), though automations and funnels unlock on Creator tiers. The editor leans plain-text and personal, great for voice, less so for image-heavy designs.

> **Kit vs. Beehiiv:** Choose Kit if you sell products and want advanced automation; choose Beehiiv if you're newsletter-first and want native growth loops. Both have strong deliverability.
