Is anyone embedding a white label email api inside their product?
Curious about the build vs embed decision for contact discovery inside SaaS products, specifically when the goal is to offer email lookup to customers without running the infrastructure yourself. The white label email api route makes sense for a lot of use cases, mainly because you get a clean data layer without owning the crawling, validation, and freshness problem, but the tradeoffs aren't always obvious before committing to an integration.
The embedding usually goes fine when all you need is a lookup endpoint, but things get complicated when customers start needing bulk operations at scale or when each customer needs their own usage quota instead of sharing a flat account limit. How are teams actually handling the quota attribution problem in a multi-tenant setup?
