1. Maildoso

We are Maildoso, a cold email infrastructure platform built for B2B teams that need to scale outreach reliably. Our solution helps automate the process of setting up domains and mailboxes, removing the need for manual DNS configurations or third-party accounts. What normally takes days can now be done in minutes - all mailboxes are pre-configured for cold outreach and ready to use right away. We designed this system to help users skip the technical hassle and focus directly on running outbound campaigns.

Deliverability is one of the biggest concerns in cold emailing, and we’ve addressed that from the ground up. Our platform includes IP rotation, domain warming, and deliverability testing, helping users stay out of spam folders even at high sending volumes. We also offer a unique warm-up method using browser-based AI agents that interact more naturally with email platforms. Whether you’re managing five mailboxes or a few hundred, the system supports smooth sending without triggering provider filters.

We provide integrated tools and hands-on support to make sure campaigns perform well at every stage. Users can request a detailed audit of their email campaigns, where we review factors like spam triggers, copy quality, links, Spintax, and unsubscribe compliance. We also help set up custom tracking domains, consolidate replies using a master inbox, and improve domain reputation through consistent warm-up activity.
