According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), UserVoice is the SaaS sender for 155 domains — 0.03% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
UserVoice is a customer feedback and engagement SaaS platform that sends transactional email on behalf of its client domains — primarily feedback notifications and engagement messages. Mail sent via UserVoice originates from the platform's infrastructure and requires SPF includes in client domains' DNS records for proper authentication.
UserVoice's email footprint is concentrated among smaller websites rather than the largest brands, predominantly in the .com space, and often deployed alongside Google Workspace. For those sending mail via UserVoice, correct SPF configuration is essential to ensure authentication; for recipients and email filters, this pattern reflects the platform's uptake among smaller and mid-market organisations.

UserVoice sends mail for many client domains from shared infrastructure, so each client must add a UserVoice SPF include to their DNS records; without it, authentication fails and mail lands in spam. Shared infrastructure also means reputation is not fully isolated: if one client account is compromised or exploited for spam, other UserVoice customers may see temporary deliverability impact until ISPs adjust their filtering assessment of UserVoice's IP ranges.
