MailAdept is a subscription-based email deliverability consulting service for businesses that rely on email as a core growth, communication, or operational channel. Instead of offering a self-serve tool, MailAdept works as an extension of your team with a dedicated deliverability expert who helps audit infrastructure, fix deliverability issues, improve sender reputation, monitor email health, and increase inbox placement over time. The service is built for companies that need ongoing deliverability execution rather than one-time advice. MailAdept reviews the full email environment across marketing, transactional, and outbound email streams. That includes authentication, DNS configuration, routing, provider setup, domain structure, blacklist exposure, sender reputation, and sending behavior. The service helps resolve SPF, DKIM, DMARC, BIMI, routing, and reputation problems that reduce inbox placement, then continues monitoring the main signals that influence email performance daily. The service is designed for teams that cannot afford deliverability issues to sit unnoticed until they hurt performance. MailAdept specifically calls out common problems like marketing emails going to spam or promotions, transactional emails not reliably reaching users, and outbound domains degrading after a few weeks. It is best suited for SaaS companies with lifecycle and transactional emails, outbound teams managing multiple domains, agencies supporting client email performance, recruiters using email as a primary acquisition channel, newsletters, and high-volume senders that need continuous support without hiring internally. It is not positioned as the right fit for teams that only need a one-time DNS fix, want a self-serve sending platform, or do not depend on email as a critical business channel. MailAdept runs on a continuous workflow. It starts with audit and prioritization, then moves into foundation fixes, daily monitoring, and weekly review and adaptation. The company positions this as an ongoing support model because email deliverability is not static: sender reputation changes, authentication can break, sending behavior evolves, and domain health shifts over time. Pricing is custom, billed monthly per domain, and includes a minimum four-month commitment, continuous support, fixes, monitoring, optimization, and weekly review sessions with an account manager and deliverability expert.
