InboxIgniter is an email warmup service aimed at agencies, marketers and sales teams that rely on cold outreach. When a new domain or mailbox starts sending at volume, inbox providers treat it with suspicion and route mail to spam. InboxIgniter solves this by automatically warming each mailbox: your accounts exchange messages with other real mailboxes in a peer-to-peer network, generating the opens, replies and conversations that make your domain look like an established, trustworthy sender.
The workflow is designed to be low-effort. You sign up, connect your mailbox through SMTP or API from providers like Gmail, Outlook, Yahoo, Yandex or Zoho, define your niche, and the platform starts warming in minutes. AI generates template content that matches your language and business context, and you can set warmup reply rates, sending frequency and schedules individually or in bulk. A dashboard shows deliverability scores, domain and email blocklists and reputation metrics so you can watch progress.
Pricing starts with a 14-day free trial with no credit card, followed by Pro and Enterprise tiers with monthly, quarterly and yearly billing. InboxIgniter also publishes free tools such as an SPF/DMARC checker, an SPF generator and a mailbox calculator, which are useful even if you only want to diagnose deliverability issues.
