Kit

Kit API v4's documented resource categories (accounts, broadcasts, custom fields, forms, subscribers, tags, email templates, posts, purchases, segments, sequences, sequence emails, snippets, webhooks) include no transactional/single-send email endpoint. No first-party product page describes a standalone transactional email offering. Some third-party listing sites carry generic 'ConvertKit transactional email' pages, but these appear to be templated review-site content, not evidence of an actual Kit product.

No SMTP relay / SMTP credential feature is documented anywhere in the Kit API v4 reference or on kit.com. Kit is a marketing broadcast/sequence platform, not an SMTP-sending product.

API v4 webhooks resource; documented event types include subscriber activate/unsubscribe/bounce/complain and form_subscribe.

Drag-and-drop multi-step automation builder with conditional-content branching by subscriber behavior. Free plan is capped at 1 basic Visual Automation (confirmed on kit.com/pricing); Creator and Pro get unlimited visual automations and sequences.

Tagging plus a dedicated Segments resource (also present in the API) with conditional rules; Pro adds 'Subscriber Signals' demographic/engagement data and custom audiences (per kit.com/pricing).

Subject-line A/B testing included from Creator up; Pro adds content + subject-line testing. Not available on the free Newsletter plan.

'SMS marketing' is listed as an included Creator-plan feature in the kit.com/pricing comparison table (not available on the free Newsletter plan). Some third-party review sites describe Kit as email-only; this may reflect content written before the feature was added and is superseded here by the vendor's own current pricing page.

Unlimited landing pages and forms, included even on the free Newsletter plan.

Dedicated 'Deliverability reporting' is listed as a Pro-only feature. Newsletter and Creator plans get general deliverability best-effort messaging (kit.com/features) but no dedicated reporting tool.

$250/month add-on, available by request once a sender meets Kit's suggested minimum volume of ~150,000 messages/week and reputation requirements. Not tied to a specific named plan tier in the source article.

First-party app installed from Kit's App Store; syncs customers/purchases, embeds products in emails, and supports abandoned-checkout recovery sequences.

Official 'Kit for WooCommerce' WordPress plugin; contributors listed on the plugin page include a 'Kit' account alongside founder Nathan Barry. Syncs customers/purchases, supports per-product subscription settings and abandoned-cart data.

No first-party Magento app found; connected only via third-party automation platforms (Zapier, Albato, n8n).

The Shopify integration supports manually embedding chosen products/collections in emails, but no evidence of an algorithmic product-recommendation engine was found. Absence not positively confirmed by a first-party source. See reports/needs-verification.md.

Shopify integration supports abandoned-checkout recovery via an automated Email Sequence referencing the specific product left behind.

Shopify revenue information and a Purchases chart showing transaction data are surfaced directly in the Kit account.

In-app messenger (Intercom-powered), help@kit.com email, a 400+ article knowledge base, and a community Facebook group. No phone support advertised.

Help article states 'Product Specialists are available 24/7' without carving out a free-plan restriction, unlike Mailchimp's documented 30-day free-plan support limit. Not explicitly confirmed whether response-time priority differs by plan.

DPA relies on Standard Contractual Clauses and the EU-U.S./UK/Swiss Data Privacy Framework for transfers; listed subprocessors operate in the USA. No EU-only data residency option is offered.

kit.com/security states that underlying infrastructure providers AWS and Cloudflare hold SOC 2 Type II / ISO 27001 certifications, but Kit itself does not claim a direct SOC 2 certification anywhere on the page.
