What Mailivery does

Mailivery, operated by SourceIT Technologies, Inc. (a corporation registered in Illinois, United States), is a product-led SaaS platform focused on email deliverability. Its core service, Email Warm Up, connects customer mailboxes to a peer-to-peer network of real, aged email accounts across Gmail, Outlook, Zoho, Yahoo, and other providers, and uses AI-generated personalized content and process automation to send, open, reply to, and rescue emails from spam folders. The goal is to build sender reputation so that outbound sales and marketing emails land in the primary inbox rather than in spam or promotions. The platform bundles Blacklist Monitoring (70+ blacklists), Email Verification (three-layer validation), Inbox Placement Test, Intelligent Sending Behavior, Team Management, and a Spam & Reputation Analytics dashboard as integrated modules; a separate free sub-brand, InboxAssist, offers top-of-funnel tools.

Mailivery serves sales and marketing teams running cold outreach, agencies managing warm-up across multiple client domains, SaaS platforms embedding warm-up functionality into their own products via REST API, and new domain owners building initial sender reputation. Revenue mechanics are subscription-based with three public tiers (Starters, Professional, Business) priced per account rather than per mailbox - explicitly differentiated from per-inbox competitor pricing - plus custom Enterprise contracts for high-volume, API, and white-label deployments. A 25% lifetime affiliate program run through FirstPromoter supplements PLG with channel-driven acquisition. Distribution is primarily self-serve through app.mailivery.io with a 7-day free trial, supplemented by enterprise demo booking via TidyCal. The company is privately held and bootstrapped, with no disclosed institutional funding, and operates as a distributed/remote team of 1-10 employees supporting a claimed 1,000+ customer base.
