(1)5.0/5

mailuj.io is a fully managed cold email outreach platform for the Polish B2B market. Unlike tools like Instantly or Woodpecker that require users to bring their own email accounts, mailuj.io registers the domain, configures SPF, DKIM, and DMARC automatically, provisions dedicated mailboxes on its own mail server, and starts warmup immediately — all from a single wizard. Users write the email copy; the infrastructure is handled end to end. Features include multi-step campaign sequencing, a Polish B2B lead marketplace (KRS-registered companies by PKD industry code), SMTP+API email verification, AI copy review, a unified inbox, and BLIK/Przelewy24 payment support for Polish customers.
