SparkPost (now Bird)
SparkPost was a transactional email platform whose brand has been retired following its acquisition by Bird: sparkpost.com now returns a permanent redirect to Bird's email product page, which we confirmed at source in August 2026. This catalog entry exists because search demand for the SparkPost name persists; the product itself is sold as Bird email today, and Bird's own catalog entry is the live listing. No separate pricing or deliverability test applies to the retired brand — any future test cycle would run against Bird.
Deliverability: not yet tested. We publish placement numbers only after running our own seed-list cycle — the method is on the how we test page — and tested services appear in the email deliverability ranking.
