According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), GetResponse is the email service provider (ESP) for 648 domains — 0.10% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
GetResponse is a cloud-based email service provider and marketing automation platform operated by GetResponse Sp. z o.o., a Polish company. The platform offers email campaign composition, audience management, automation workflows, and basic customer relationship management tools, targeting small and medium-sized businesses and independent marketers rather than enterprises.
GetResponse's footprint in the Internet's email infrastructure, visible through SPF authorisation mechanisms, is typical of a mid-market ESP: internationally dispersed across many domain extensions but concentrated among smaller and mid-sized websites rather than the largest properties. A common pattern is deployment alongside Google Workspace, suggesting that organisations using GetResponse often adopt the same basic cloud-platform stack. For deliverability professionals, this footprint indicates that GetResponse senders often represent smaller campaigns rather than high-volume bulk mailers, which affects reputation pooling and sender-composition assumptions.

GetResponse operates as a multi-tenant platform where thousands of independent senders share authorised sending infrastructure. The SPF includes pointing to GetResponse across the Internet represent not a single coherent sender but a collection of many independent customers, each launching email campaigns under the same authorised pool. In multi-tenant systems, sender reputation is aggregated—abuse or poor compliance by one tenant degrades delivery for all others sharing the infrastructure. Mail receiving systems typically treat ESP traffic more conservatively than direct-send traffic as a result. Organisations evaluating whether GetResponse traffic warrants testing or allowlisting should recognise that a single SPF include may represent hundreds of independent senders with varying list quality, compliance discipline, and sending practices.

Testing against GetResponse is worthwhile if your recipients use the platform or if you encounter Google Workspace organisations alongside it, as that combination is common. However, because GetResponse's sender pool is diverse and reputation is pooled across many independent tenants, testing against a single GetResponse endpoint may not fully predict delivery to all GetResponse users.
