Marketing automation platforms help teams manage repetitive work such as audience segmentation, lifecycle messaging, lead nurturing, and campaign orchestration. The right choice depends on business model, data requirements, channels, team size, and integration needs.
The eight products below are established options to evaluate rather than a universal ranking. Product packaging, prices, native integrations, and usage limits change frequently, so confirm each requirement directly with the vendor before purchasing.

Klaviyo
Klaviyo is a B2C CRM and marketing automation platform used for customer-data-driven email, SMS, segmentation, and lifecycle messaging. Review its current integrations and API documentation against the commerce platforms and data flows you need.
HubSpot
HubSpot combines CRM, marketing automation, content, analytics, and related customer platform tools. It can suit teams that want marketing and sales activity connected in one ecosystem, but the required features depend on the selected hubs and subscription tier.
Microsoft Dynamics 365 Customer Insights - Journeys
Dynamics 365 Marketing is now Dynamics 365 Customer Insights - Journeys. The current application focuses on real-time, trigger-based and segment-based customer journeys; the legacy outbound-marketing module has reached end of life.
Keap (formerly Infusionsoft)
Infusionsoft was rebranded as Keap. Keap focuses on CRM, sales, email, and automation workflows for small businesses; current editions and feature availability should be checked on the vendor's site.
ActiveCampaign
ActiveCampaign provides email marketing, automation, audience segmentation, and CRM capabilities. It is worth evaluating when a team needs multi-step lifecycle automation, but the fit depends on contact volume, channels, and required integrations.
Bluecore
Bluecore is a retail-focused customer and marketing platform for audience activation, personalized messaging, and lifecycle use cases. Prospective customers should confirm data onboarding, channel coverage, and commerce-platform support with Bluecore.
Adobe Marketo Engage
Adobe Marketo Engage is Adobe's enterprise marketing automation product. It supports campaign orchestration, segmentation, lead and account workflows, and connections to external systems.
Omnisend
Omnisend is an eCommerce-focused email and SMS marketing automation platform. Evaluate its current channel support, store integrations, automation limits, and pricing against your expected contact and message volumes.
Shopping cart integration for marketing automation software
Marketing automation software that serves eCommerce merchants may need access to customer, order, cart, product, and category data from multiple shopping platforms. Building each connection separately creates additional mapping, testing, and maintenance work.
API2Cart provides one unified API for 70+ supported shopping carts and marketplaces. A software vendor can use that integration layer instead of maintaining a separate connector for every supported platform.
Schedule a call with our representative to learn more about how API2Cart can work for your business.
