Warmbly
Warmbly is an open-source cold outreach platform that brings email warmup, campaign sending, a unified inbox, analytics, and CRM together. Campaign sequences can branch based on opens, clicks, or replies, include A/B variants, and send follow-ups in the same conversation thread. Sending can be restricted to weekday working hours in a selected timezone. The inbox classifies replies, bounces, out-of-office messages, and clicks across connected mailboxes. Warmbly is available on the web and through an API, or can be self-hosted under Apache 2.0. When a self-hosted installation connects to Warmbly Cloud for warmup, campaigns, contacts, and inbox data remain on the self-hosted server. Integrations include HubSpot, Salesforce, Pipedrive, Close, Zapier, Make, n8n, Slack, Discord, Calendly, and Cal.com; Google Sheets lead sync is available on demand. The free warmup pool supports up to 10 mailboxes. Paid campaign plans include Starter at $23 a month billed annually, with 150 emails per day, and Grow at $71 a month billed annually, with 3,000 emails per day.
