Migrate your tenant.
Zero emails lost.

Important: We are an email queuing service only. We do NOT migrate files, users, data, calendars, contacts, or any other tenant information. We specifically handle email queuing during your tenant migration to ensure no emails are lost while you move everything else. Think of us as a temporary mailbox that holds your mail while you're moving to a new address.

Tenant Migration Queue queues emails when your tenant is offline and releases them when ready. Email Forwarding provides zero downtime by immediately forwarding emails to placeholder addresses or .onmicrosoft.com accounts during migration. The Hybrid approach lets you forward critical addresses while queuing the rest.

Email Forwarding requires you to define every user and their forwarding destination, providing zero downtime for all configured addresses. Hybrid combines both approaches: you can forward up to 10 high-value email addresses (like CEO, sales, support) for zero downtime delivery, while all other users are automatically caught in the queuing system. This gives you the best of both worlds - immediate delivery for critical addresses without the need to configure every single user in your organization.

Emails can be held at your request for up to 45 days, giving you plenty of time to complete your tenant migration. Once delivered and you terminate the service, all emails are securely deleted according to our secure deletion policies.

No. Unlike other services, we have no limits on mailboxes, storage, or messages. Our flat fee covers unlimited usage during your migration. That said, if you're a massive enterprise, we'd appreciate a heads up before you start. Your price won't change, but it's nice to chat before something this important for your organization - we want to ensure everything goes perfectly for you.

Think of it as a DVR for your emails (for those who remember them). If delivery fails due to a configuration issue, you can essentially rewind time and replay the message delivery after fixing the problem - all before panic sets in. No more "those emails are gone forever" moments. Just fix, replay, and deliver.

We prevent NDR (Non-Delivery Report) notifications from being sent to original senders during migration. This avoids confusion and maintains professional communication with your contacts.

We are SOC 2 Type II certified. We also provide Data Processing Agreements (DPA), Cloud Services Terms, and complete responses to standard security questionnaires.

This is a completely self-service product. Complete your order and the migration service is ready to run immediately. Just follow the instructions in the email - you'll be queuing emails within minutes.

We support all email platforms including Office 365, Google Workspace, Exchange, and any other email server. We're completely mail server agnostic.

Once your emails are delivered and you terminate the service, all emails are securely deleted according to our strict data deletion policies. We ensure complete data removal with no retention beyond your service period.

Absolutely yes! Our suggestion would be to use a VPS provider like DigitalOcean, configure an email server like Postfix, request unblocking of port 25, test compulsively, and in the 4+ hours it takes (not including support requests to unblock port 25), you could have moved onto more important migration tasks. Plus, you'd lose our Message Replay safety net feature and 24/7 support. For $647, we handle all the complexity while you focus on what matters - your actual tenant migration.

This is an email migration, not a tenant migration. A tenant migration is a very specific issue where you can't assign the same domain to multiple accounts simultaneously on the same provider (like moving between Office 365 tenants). However, you CAN have the same domain on different providers. So for 365-to-Google or Google-to-365 moves, you typically just need to change MX records - no email queuing required. That said, some customers still prefer using our service during their migration window for extra safety and the ability to control email flow timing.

When configured correctly, SPF, DKIM, and DMARC records are properly identified and handled without any issues on delivery. Our servers maintain the authentication chain, ensuring your emails pass authentication checks and maintain their reputation during the migration process.
