1. Maildoso

At Maildoso, we focus on making cold email infrastructure fast, scalable, and easy to manage for B2B outreach. Instead of spending days setting up mailboxes and domains manually, we let users create hundreds  even thousands - of mailboxes in just a few clicks. Everything comes pre-configured and ready for outbound campaigns, so you can focus on sending emails rather than dealing with technical roadblocks.

We’ve built our platform with deliverability in mind. Our AI warmup tool works in-browser, performing real user-like actions that help keep emails out of spam folders. We also use IP rotation behind the scenes. If an IP runs into issues, we switch it out automatically to maintain strong sender reputation. Our clients have seen deliverability rates as high as 95% when sticking to plain-text messaging without links or images.

Pricing is straightforward and built for growth. We offer one of the most affordable options for cold email infrastructure. Domains are included at no extra cost - and they’re yours to keep, even if you cancel your subscription. That kind of flexibility is especially useful for agencies managing multiple client campaigns.

In addition to setup and infrastructure, we offer campaign audits and deliverability checks. Our team can test your emails for spam triggers, review your domain setup, and help optimize your outreach strategy. With tools like the Master Inbox and domain forwarding, we try to make managing high-volume cold outreach as simple as possible.
