Our verdict on Quickly
Quickly is an open-source cold email platform for sales teams, agencies, and independent users that want to manage outreach on their own infrastructure. Its web and self-hosted deployments support multi-step sequences, configurable follow-up timing, Gmail and Microsoft 365 OAuth2 sending, inbox rotation, warm-up scheduling, send-time jitter, bounce detection, and automatic lead stopping. A unified inbox with threaded replies, AI reply classification, campaign analytics, and tracking extend it beyond basic sequencing.
The published product details show a free, MIT-licensed software model rather than subscription tiers. There are no software subscription fees, while hosting and third-party infrastructure costs are handled separately. Self-hosting uses Docker and PostgreSQL, so Quickly fits organizations that can manage deployment and infrastructure themselves. Its ecosystem covers Gmail, Microsoft 365, Outlook.com, SMTP relays, Amazon SES, Brevo, IMAP, n8n, and MCP clients. Webhooks and a REST API also support custom workflows and connections to external systems.
Quickly’s strongest focus is operational control for cold-email campaigns: inbox rotation, warm-up scheduling, reply detection, analytics, A/B testing, and automatic stopping after bounces are grouped in one application. Template variables and CSV import provide basic personalization, but the published feature set does not position it as a highly personalized outreach platform. Choose Quickly if self-hosting, open-source distribution, mailbox flexibility, and API access matter more than managed infrastructure. Teams seeking a fully managed service or deeper personalization should consider a different type of cold-email platform.
