Yes - live SMTP verification against all three Polish freemail giants: Onet (onet.pl, op.pl), WP (wp.pl, interia.pl, o2.pl), and Gazeta (gazeta.pl). Each has distinct SMTP infrastructure handled separately.
RODO is the Polish implementation of GDPR. Enforced by UODO (the Polish data protection authority). It requires accurate contact data - invalid email addresses should be removed from your database.
Users migrate from Onet/WP/Interia to Gmail steadily. Lists built over 3-5 years without cleaning commonly show 15-25% invalid rates from Polish freemail decay alone.
