Outbox — Private Gmail Outreach Platform

A responsible outreach workflow has more moving parts than composing an email. Contacts must be imported and deduplicated, audiences must be selected deliberately, personalization data must remain usable, Gmail accounts need secure authorization, and every campaign needs clear limits and readiness checks before launch. Follow-ups also need to stop when a recipient replies, while the operator needs enough history to understand sent, queued, skipped and failed work. Generic tools left these decisions fragmented or hidden behind features that did not match the client’s operating process.

I designed and built a role-protected Django application around the complete campaign workflow. Contacts can be created individually or imported from CSV with mapped custom fields, then organized through lists, tags or direct selection. A guided campaign builder connects audience, reusable rich or plain-text templates, sequence steps, Gmail sender identities and a final readiness review.

The sending layer applies account and campaign caps, controlled delays, dry-run testing, sender rotation and pause-on-reply behaviour. Gmail access uses OAuth and encrypted token storage. Dashboards and logs expose campaign status, remaining capacity, delivery attempts and reply-rate signals. New accounts remain inactive until an administrator approves them, preserving the product as a private business application even though its login URL is public.
