Cold outreach dies in the spam folder long before a prospect reads it, and Warmbly is the open-source platform that keeps your mailboxes warm, capped, and credible while campaigns run from the accounts you already own. Connect Google Workspace, Microsoft 365, or any SMTP and IMAP mailbox, and Warmbly checks SPF and DMARC records, scores mailbox health, then warms each account gradually, starting near 10 messages a day and ramping toward a 40-per-day ceiling instead of blasting from day one. Campaigns run as multi-step sequences spread across many mailboxes, with per-mailbox daily caps, minimum spacing between sends, and weekday sending windows, so volume grows without one account absorbing all the risk. Opens, clicks, bounces, and complaints stream into a deliverability view with suppression handling, while every reply from every mailbox lands in one unified inbox your whole team can work in real time. A built-in CRM tracks contacts, pipelines, deals, tasks, and meetings next to the conversations that created them. Visual playbooks react the moment a reply, booking, bounce, or warmup dip arrives: branch on intent or confidence, let an AI step read the reply and act only with the actions you allow, open the deal, post to Slack, update HubSpot or Pipedrive, and test the whole path on a canvas before it goes live.

Larasend gives Laravel teams a self-hosted transactional email platform that sends through their own Amazon SES or Cloudflare account while keeping the dashboard, delivery logs, and message data on their own servers. Send mail with a simple POST to the emails API, or point existing mailables and notifications at the Larasend transport with one environment variable and no code rewrite. Every message lands in an activity dashboard where you can filter by status, search recipients and message IDs, open a preview with headers and metrics, and resend failures in one click. Delivery, bounce, complaint, open, and click events stream back from the provider and update each message timeline, so a missing receipt becomes a traceable record instead of a support mystery. Suppression lists build themselves from bounces and complaints, and guardrails watch complaint rates and verified domains before reputation damage can spread. Scoped API keys with expiration and rotation keep each project separate, while workspace roles control who can view, send, and administer. When replies arrive, the shared inbox threads inbound and outbound mail into conversations your team can assign, snooze, annotate, and answer with attachments and drafts. Webhooks notify your other systems about deliveries and inbound mail, and reusable templates keep recurring notices consistent across projects.
