About
Mailreef is a cold email mailbox infrastructure platform built by cold emailers to make delivery and scaling easy. Its mailboxes are designed to rival Google, Zoho, and Outlook while giving outreach teams a cold-email-friendly environment with dedicated mail servers, dedicated IP addresses, bring-your-own-domain support, and unlimited inboxes. It lets users create domains and mailboxes in one click, with SPF, DKIM, and DMARC automatically configured so teams do not have to manage DNS records manually. Mailreef is built for teams that need to scale cold email campaigns without wasting time creating accounts, setting up fake profiles, or dealing with mailbox blocks from traditional providers. Its infrastructure supports day-one campaign readiness through pre-warmed servers, pre-warmed domains, and pre-warmed mailboxes, helping teams start outreach faster while maintaining stronger deliverability foundations.

About
Sellvance is a GTM experimentation platform for B2B SaaS teams still searching for product-market fit. Validate an ICP, test an offer, or check demand for a feature by talking to real prospects.
Most cold email tools are built for volume. But zero replies can mean nobody wants your product, or that your emails never reached the inbox. Sellvance tells them apart. Every experiment gets a Signal Check: a delivery verdict (did the emails arrive?), an interest verdict (is the positive reply rate above your threshold?) and a harm verdict (unsubscribes). Until delivery is confirmed, Sellvance won't let you judge the reply rate.
Includes a 9.5M+ company database, enrichment with AI agents, AI-written messages, in-app domains and mailboxes, deliverability monitoring, and an MCP server to run campaigns from Claude.
Free Experiment Plan, no domain or mailbox needed. Paid plans from $199/month.
