According to Live Direct Marketing's daily Tranco top-1M scan (July 12, 2026), SendPulse is the email service provider (ESP) for 2,880 domains — 0.47% of 617,244 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
SendPulse is an email service platform that provides bulk mail delivery, marketing automation, and transactional email sending for organisations of various sizes. The platform is identified in email infrastructure audits through its presence in SPF records, where it appears as an authorised sending mechanism for domains that route mail through SendPulse's mail relay and SMTP services.
SendPulse's footprint skews towards mid-market and smaller organisations rather than the largest enterprises, with adoption spread internationally across many country-level domains but concentrated in the .com namespace. Its frequent co-appearance with Google Workspace suggests a common pattern whereby businesses run their primary email on Workspace but outsource bulk or marketing mail to SendPulse—a strategy to isolate transactional and promotional traffic from core domain reputation.

SendPulse's visibility in SPF records reflects its role as an outsourced sending platform; organisations authorise SendPulse by adding its SPF include to their domain policy. This centralises authentication credentials and IP reputation at the ESP level, which simplifies administration for smaller organisations but ties deliverability to SendPulse's compliance practices and IP reputation management. Accuracy in SPF and DKIM configuration is therefore essential to avoid authentication failures and inbox filtering.
