According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), eSputnik (UA) is the email service provider (ESP) for 1,054 domains — 0.17% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
eSputnik is a Ukrainian email service provider focused on marketing automation and bulk email delivery for small and mid-market businesses, particularly in Eastern Europe. The platform is operated by the eSputnik development and support team and has built its customer base primarily through regional presence and direct integration with Google Workspace, making it a common choice for organisations seeking local technical support alongside their email infrastructure.
eSputnik's presence in email SPF records across the wider internet reflects its role as a long-tail provider: it appears in smaller sites' DNS configurations far more often than in the top-tier brands, distributed across many international TLDs but concentrated among Ukrainian (.ua) registrations. For deliverability engineers and system administrators, this footprint pattern means that SPF include mechanisms for eSputnik are common enough to warrant monitoring, that reputation with major mailbox providers differs from that of larger consolidated ESPs, and that understanding regional mail practices matters when troubleshooting delivery from eSputnik-sending organisations.

eSputnik uses SPF include directives to authorise its outbound mail infrastructure, requiring customers to add the provider's include string to their sender policy. Because eSputnik's customer base consists of many dispersed senders rather than a few large brands, its authorised IP space spans multiple ranges and the include string itself resolves to several lookups within the SPF query limit. Organisations using eSputnik must ensure SPF is correctly configured and should be particularly cautious of SPF flattening when combining eSputnik with other mail providers, as the DNS query limit (ten lookups per SPF check) can quickly be exhausted when multiple includes are stacked, leading to mail rejection during validation.
