The ActiveCampaign alternative with transactional email built in
ActiveCampaign is a powerful marketing automation tool, but it has no transactional email API and charges by contact count. Sendkit gives you transactional emails, campaigns, and automations in one platform — priced per email, not per contact.
Why teams switch from ActiveCampaign
No transactional email API
ActiveCampaign is marketing-only. Need to send password resets, receipts, or order confirmations? You'll need a separate service. Sendkit includes transactional email with full API and SMTP support on every plan.
Contact-based pricing scales steeply
ActiveCampaign charges by contact count. At 10K contacts, you're paying $174/mo on the Lite plan. At 25K, it jumps to $286/mo. Sendkit charges per email sent with unlimited contacts on every plan.
Complex for simple needs
ActiveCampaign is built for advanced marketing automation. If you just need to send emails with a clean API, the complexity gets in the way. Sendkit is developer-first with a straightforward API.
No MCP server
ActiveCampaign has no MCP server for AI agents. Sendkit has a full MCP server with 40+ tools — your AI agent can manage templates, send campaigns, segment contacts, and track metrics.
