Universal Connector
A provider-neutral engine for migration, synchronization and continuity between mail platforms. Gmail, Microsoft, IMAP, Stalwart and whatever comes next.
Active developmentInfrastructure and technology to move, operate, protect and decouple email from any single provider.
SecondMailer is the umbrella for a set of technologies built around email mobility, continuity and control. The backend can change. Your ability to move should not.
A provider-neutral engine for migration, synchronization and continuity between mail platforms. Gmail, Microsoft, IMAP, Stalwart and whatever comes next.
Active developmentEmail beyond the mailbox. A future abstraction layer for identities, routing, search, policy, synchronization and provider-independent operations.
Research / developmentWe work on the parts of email infrastructure that become painful precisely when they matter most.
Move mailboxes, domains and historical mail without treating IMAP copy as a strategy.
Self-hosted, on-premise and private-cloud architectures with control of data and standards.
Keep mail moving while providers, platforms or infrastructure change underneath it.
Separate historical mail from active mailboxes without losing searchability or ownership.
DNS, routing, reputation and message flow treated as one operational system.
Automation, recovery, observability and the unglamorous details that make email dependable.
Open standards.
Portable data.
No hostage situations.
SecondMailer starts from real operational problems: migrations, large historical archives, Gmail and Microsoft ecosystems, Stalwart, DNS, routing, deliverability and continuity.
The goal is not another mailbox subscription. It is to make email infrastructure easier to move, understand and control.
