Description

InboxFlow transforms your cold email setup from the very beginning. When you acquire your temporary domains, we handle the automation of SPF, DKIM, and DMARC configurations.

Furthermore, InboxFlow’s bulk-account upload capability enhances your cold emailing strategy significantly. We supply a CSV file that enables you to easily import and oversee multiple inboxes within your preferred sending platform. Wave goodbye to cumbersome, manual workflows and welcome an era of enhanced efficiency. By streamlining your cold email foundations, you can achieve exceptional deliverability rates with ease. Effortless management of your email outreach has never been more achievable.

Description

SubsiMail is a platform for self-hosted cold email sequencing, allowing users to manage prospect lists, templates, connected inboxes, and all campaign-related data directly within their own database rather than relying on a third-party SaaS solution. Designed as an alternative to platforms like Instantly, Smartlead, lemlist, and Apollo, it offers flat pricing based on connected inboxes instead of per-seat charges, ensuring complete ownership and export of data without any content review processes or external access to contacts and campaigns. The application operates seamlessly as a single Docker container on any $5 VPS, enabling users to connect to Gmail, Outlook, or any SMTP/IMAP inbox, create multi-step email sequences that incorporate merge fields and reply detection, manage user roles (admin, manager, view-only) while maintaining a comprehensive audit trail, and utilize integration through a REST API secured by personal API keys. Furthermore, the initial connected mailbox comes with a perpetually free option, making it an attractive choice for individuals and businesses alike. This unique setup empowers users with greater control over their email marketing campaigns while simplifying the management process.
