Key facts

Why Tapfiliate appears in this category

Dutch affiliate-marketing SaaS sending tracked notifications.

We classify it as a email service provider 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.

Tapfiliate is an email service provider and affiliate-marketing platform that enables organisations to manage transactional and marketing email alongside affiliate programme administration; it appears in email infrastructure when senders authorise it via SPF include mechanisms. The service supports sending workflows for organisations whose mail needs combine transactional notifications, marketing messages, and affiliate-programme communications.

The presence of Tapfiliate in email headers indicates deployment by smaller or mid-market organisations rather than large enterprises, with concentration in the .com top-level domain and frequent co-occurrence alongside Google Workspace. This pattern suggests adoption primarily among small businesses managing their own sending infrastructure and affiliate systems, rather than the multi-provider mail stacks typical of large organisations.

SPF Authentication and Shared Infrastructure Reputation

When Tapfiliate appears in a domain's SPF record via an include mechanism, receiving mail servers recognise it as an authorised mail handler for that sender. This shared-infrastructure model means deliverability depends on both the sender's own domain reputation and Tapfiliate's standing with receiving ISPs; poor sending practices by other platform users can affect message acceptance for unrelated senders using the same service, making reputation monitoring essential.
