Act-On scores C+ on the API Report Card. A self serve REST API at developer.act-on.com covers contacts, segments, programs, messages, and reports, with webhooks for form and program events. Admins generate keys in settings and a free developer account is open. Professional plans cap at 30,000 API calls a day.
Act-On has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood.
Act-On is a cloud-based lifecycle marketing automation platform that combines email and SMS campaigns, multi-step automated programs (journeys), landing pages, forms, lead scoring, website visitor tracking, social publishing, event/webinar promotion, and bidirectional CRM sync into a single mid-market product.
Vertical: Marketing automation / email marketing (horizontal SaaS, not industry-specific). Marketers build email and SMS campaigns in a drag-and-drop composer, segment contacts using Act-On's segment builder (now Act-On Contacts), and orchestrate multi-step Automated Programs triggered by form fills, list membership, behavioral scores, website page visits, or CRM events.
Act-On reports roughly 4,000 customers and ~$16M-$44M in TTM revenue (the Banzai acquisition press release cited a combined TTM of $44M after the deal closed), placing it firmly in the mid-tier of the marketing automation market.
Yes, for any business that runs lifecycle marketing on it, Act-On is the system of record for the marketing engagement dataset: the full contact and account database with custom fields and segments, every behavioral event (page views, form submissions, content downloads, email opens/clicks, SMS interactions, webinar registrations and attendance), every Automated Program entry/exit and step history, lead and behavioral scores, the suppression and consent state for each contact, attribution and funnel-velocity report data, and the bidirectional sync state with the connected CRM (Salesforce/Dynamics/Sugar/NetSuite).
Founded in 2008 in Portland, Oregon by Raghu Raghavan (previously a co-founder of Responsys). Initially distributed exclusively through a $2M-funded Cisco partnership, then went direct.
Daily API call ceiling of 30,000/day on the Professional plan is restrictive for high-volume bidirectional CRM sync or product-event firehose use cases. Act-On is in the middle of a multi-year migration from legacy 'marketing lists' endpoints to the new 'Act-On Contacts' endpoints, forcing integrations to support both data models during the transition.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
