Why Groove appears in this category
Groove — SMB shared inbox / helpdesk.
We classify it as a SaaS sender from include: mechanisms in the SPF record matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
Groove is a cloud-based email platform that enables organisations to send transactional and marketing email on behalf of their own domains. The service manages message queuing, delivery, bounce handling, and compliance, positioning itself as an alternative to in-house SMTP infrastructure or heavier enterprise solutions.
Its presence in email infrastructure is notably diffuse: Groove appears primarily in smaller organisations and mid-market sites rather than the largest global brands, and is most prevalent in the .com space. The frequent co-occurrence of Groove with Google Workspace in SPF records indicates a common infrastructure pattern among smaller organisations, suggesting that Groove complements rather than replaces Google Workspace in the email stack.

Groove's Multi-Tenant IP Architecture and Shared Reputation
Groove operates shared IP ranges across multiple customers, meaning each sender's reputation can be affected by the behaviour of other users on the platform. If other Groove customers experience abuse complaints, maintain poor list hygiene, or trigger spam filter blacklists, legitimate senders may experience deliverability degradation even if their own practices are sound. This dependency on collective reputation underscores the importance of robust bounce handling, complaint monitoring, and proper authentication (SPF, DKIM, DMARC) validation when delegating email delivery to any third-party service.
