A high-performance, self-hosted outreach engine optimized for maximum deliverability and privacy. Scale campaigns seamlessly, connect unlimited email accounts, parse nested spintax, and protect your domain reputation—all powered by your local machine with secure cloud synchronization.
Raw desktop power combined with sleek cloud mechanics
Unlike web-based subscription outreach systems that charge monthly fees per inbox, Epta Sky Outreach Pro runs completely on your machine, giving you full command of your leads and data.
Connect as many custom SMTP, Gmail, Outlook, or IMAP nodes as you need. There are absolutely no limitations or extra monthly fees based on seat count.
Configure smart sending pacing utilizing `delay_min` and `delay_max` pauses. Set batch counts and custom `batch_pause` intervals to bypass filters and protect your domain reputation.
Local database records synchronize seamlessly with secure cloud storage. Protect and back up your email accounts, warmups, templates, and campaign logs in real-time.
Organize thousands of leads and accounts into separate client groups. Program targeted templates and specify unique sending speeds across different outreach categories.
Ensure perfect delivery and variety in every prospect email. Rotate intros, pitches, and Signatures seamlessly using nested spintax formatting (e.g. `{Hi|Hey|Hello}`).
Quickly import lead lists via structured CSVs containing hundreds of custom variables. Attach unique personalized dynamic documents directly to individual emails.
Experience the technology live before downloading
Test out the core capabilities of our spintax spinner and visual sending delay planner right here on the landing page.
Provide nested bracket options separated by vertical pipes. The spintax compiler picks options randomly at sending runtime, ensuring you never dispatch identical sequences to bulk leads.
Adjust the range slider to simulate your minimum pacing interval. Witness how Epta Sky's local scheduler spaces out personalized emails to prevent spam detection.
Local-first speed synchronized to the cloud
Epta Sky is engineered as a local-first desktop database powerhouse. It operates completely independently of internet uptime, executing lightning-fast transaction queues on your machine's SQLite DB using WAL (Write-Ahead Logging) optimization.
Zero lag operations. Campaigns, settings, parsed spintax configurations, and lead caches persist directly inside your device's optimized SQLite engine.
As soon as you authenticate via the secure portal, Epta Sky establishes an encrypted tunnel and automatically backs up your local campaign states and sequences.
Your valuable SMTP configurations, credentials, and API nodes are fully encrypted and kept within your private, dedicated cloud vault. They are never exposed.
Frequently Asked Questions
Everything you need to know about Epta Sky Outreach Pro security, synchronization, and platform operations.
Yes, absolutely! The desktop software runs completely locally on your personal hardware. You hook up your own SMTP/IMAP credentials and save records inside a highly cost-efficient private cloud vault. You never pay monthly subscription fees per connected inbox!
When you initiate authentication, the desktop client spins up a secure local listener on port `5050` and redirects you to verify via your system browser using industry-standard secure Single Sign-On (SSO). Once validated, an encrypted session token is securely passed back to your local client, enabling automated real-time backups.
Without question. All of your sensitive SMTP/IMAP credentials, lead lists, and settings are saved on your own hardware inside the local SQLite database. When cloud backup is active, data is uploaded securely straight into your private, dedicated cloud storage vault, meaning we have zero access or exposure to your credentials.
Epta Sky is extremely lightweight! Any standard machine running Windows 10 or 11 with at least 4GB of RAM and 100MB of free storage space can easily run the PyWebView desktop compiler and schedule campaigns without lagging.
