GetResponse API
GetResponse runs a self-serve REST v3 API: generate a key in account settings or use OAuth 2.0 for third-party apps, with webhooks for subscribe, open, and click events. Mind the quirks: unused keys expire silently after 90 days and rate limits only surface as production 429s.

GetResponse scores C on Supergood's API Report Card. GetResponse runs a self-serve REST v3 API: generate a key in account settings or use OAuth 2.0 for third-party apps, with webhooks for subscribe, open, and click events. Mind the quirks: unused keys expire silently after 90 days and rate limits only surface as production 429s.
GetResponse 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. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
GetResponse is a cloud-based email marketing, marketing automation, and conversion platform that bundles email campaigns, AI-assisted content generation, visual automation workflows, landing pages, signup forms and popups, a website builder, webinars, SMS marketing, web push notifications, sales funnels, abandoned-cart recovery, AI product recommendations, course creation, and conversion tracking into a single SMB-to-enterprise product.
Vertical: Email marketing / marketing automation / webinars (horizontal SaaS, not industry-specific). Marketers build email campaigns and newsletters in an AI-assisted drag-and-drop designer, segment contacts by behavior and custom fields, and chain together visual marketing automation workflows triggered by signups, tag changes, abandoned carts, link clicks, webinar attendance, or API events.
GetResponse reports 350,000+ paying customers across 160+ countries and is consistently named in 'best email marketing platform' lists alongside Mailchimp, ActiveCampaign, Brevo, MailerLite, and Kit.
Yes, for any business running lifecycle marketing, webinars, or course funnels on GetResponse, the platform is the system of record for the entire customer engagement dataset: the full contact database with custom fields, tags, and consent status; every email, SMS, and web push send with open/click/bounce/unsubscribe history; every marketing automation entry/exit; landing page and form conversions; webinar registrations and attendance with engagement metrics; online course enrollment and progress; ecommerce events (cart events, orders, product views) synced from Shopify/WooCommerce/Magento/PrestaShop; transactional email; and, for MAX customers, multi-account, dedicated-IP, and SSO configuration.
Founded 1998 in Gdansk, Poland by Simon Grabowski as one of the first commercial autoresponder services; bootstrapped to profitability without major VC funding.
API keys silently expire after 90 days of non-use, breaking long-running background syncs without warning. Rate limits are not clearly published in the public docs, developers must discover them through 429 responses in production. Full sourced list under Sources below.
Common alternatives include Mailchimp (Intuit), ActiveCampaign, HubSpot, Klaviyo, Brevo (Sendinblue), Constant Contact. Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. As of August 2026 there is no official GetResponse MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. GetResponse doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
