# Warmerly > Warmerly is cold outreach software built around deliverability: it warms up your Gmail and Outlook mailboxes until providers trust them, then sends your campaigns from them. It covers email warmup, multi-step sequences across email and LinkedIn, a unified reply inbox for email, LinkedIn and WhatsApp, a B2B lead database, email finding and verification, and daily SPF/DKIM/DMARC monitoring. It also works as warmup alone alongside Instantly, Smartlead, lemlist or Apollo. Warmerly runs Warmflow, continuous human-like email warmup, monitors placement and reports mailbox health via InboxPulse, and rescues messages from spam. It sends cold email campaigns and multichannel sequences (email, LinkedIn) from the same warmed mailboxes, with a unified inbox for replies from email, LinkedIn and WhatsApp. Email plans start at $19/month for 5 mailboxes ($49 for 25), with warmup included on every mailbox and no cap on campaign sends; there is a free plan with no card. OneMail hosted sending mailboxes, with DNS set up automatically, cost $2.99 per mailbox per month ($1.99 on Growth, $0.99 on Agency) and do not use a plan mailbox slot. Warmerly Link (LinkedIn warmup and outreach) is a standalone $50 USD/month per-account product with no trial or base-plan requirement. ## What is email warmup? Email warmup is the process of gradually sending and engaging with mail from a new or low-volume sending mailbox so that providers like Gmail and Outlook learn to treat it as a trusted human sender. A warmup tool such as Warmerly connects to your mailbox securely and runs continuous, human-like conversations (sends, replies with quoted history, stars, label, mark important, and spam-folder rescue) against an aged peer pool, building the baseline reputation a mailbox needs before any cold outreach is sent. ## Product - [Home](https://warmerly.com/): What Warmerly does, who it is for, and how it lands you in the inbox. - [Features](https://warmerly.com/features): Email warmup, cold email campaigns and multichannel sequences (email, LinkedIn), unified inbox with WhatsApp, lead database, email finder and verification, inbox-placement and DNS monitoring. - [How it works](https://warmerly.com/how-it-works): The warmup model: peer pool, human-like sends and replies, daily ramp, and placement tests. - [Pricing](https://warmerly.com/pricing): Email and WhatsApp tiers from $19/mo; Warmerly Link (standalone LinkedIn warmup + outreach) is $50 USD/month per account. - [Transactional email API](https://warmerly.com/transactional-email): A separate product: a REST API for an app's own email (password resets, receipts), kept apart from outreach and warmup.
