Cold Cannon is a web-based cold email platform created for sales teams, agencies, freelancers, and outbound operators who want to manage outreach in one place. Instead of relying on separate tools for campaign management, warmup, and email workflo…

Every extra prospecting tool is a place your best replies go to die. Mailgent puts LinkedIn automation, cold email, AI responses, and a shared inbox in one workflow so a full multichannel campaign runs — and gets managed — without a browser full of tabs.
Outbound teams juggle five or six tools to run a single LinkedIn-plus-email sequence, and every extra login costs a reply. Mailgent collapses that stack into one workflow so a LinkedIn touch and an email follow-up become steps in the same timeline, and the replies land in one inbox instead of scattering across half a dozen tabs.
The core of the app is a sequence builder that treats LinkedIn actions and email actions as first-class citizens on the same timeline. Branching, delays, and inbox rotation sit inside that same builder rather than being bolted on as afterthoughts.
The tool is aimed at outbound-heavy operators who already know their playbook and want to stop babysitting it. Lead-generation and sales agencies get the multi-account layout to run several clients from one dashboard without switching browsers. Recruiters use it to keep candidate conversations from vanishing across three platforms — LinkedIn, Gmail, and whatever ATS they were pasted into. B2B SaaS teams and small SDR crews get most of the operational surface they'd expect from a five-tool stack, in one place. Consultants and B2B founders who can't justify a full-time SDR use it to keep pipeline warm without giving up two hours a day to prospecting drudgery.
Setup starts with connecting your LinkedIn profile and email accounts — Gmail, Outlook, SMTP/IMAP, and SendGrid are all supported. From there you build a sequence in the visual editor, mixing LinkedIn steps, email steps, delays, and branching. Prospects come in from a CSV, Sales Navigator, a LinkedIn search, or a list of people who commented on a post. Mailgent then runs the outreach against the account limits and pacing you set, rotating sends across mailboxes and optionally warming inboxes before it does. Replies land in the Unibox where you can answer them yourself, let the AI draft a response for approval, or turn on full auto-reply for standard follow-ups. Connections, opens, clicks, replies, and campaign performance surface in one dashboard rather than three.
Entry pricing starts at $149 and covers one LinkedIn account, 25 mailboxes, the multichannel campaign engine, unified inbox, analytics, auto-replies, and one Intent Agent. Two higher tiers open the door to three or five LinkedIn accounts and 75 or 150 mailboxes for agencies running heavier volume across clients.
