Best Shopify Email Apps for List Hygiene in 2026
List hygiene is a recurring operating practice: record consent, suppress opt-outs, remove invalid addresses, review engagement, and understand why a segment is being mailed. A clean list is not simply a smaller list.
We prioritize suppression, source quality, engagement review, authentication, and clear separation between marketing and transactional streams. Confirm current vendor guidance and pricing from official sources before changing sending volume.
