Move from Warmy to Bird deliverability tools

Warmy offers mailbox warmup and deliverability tools. Identify whether the job is preparing an individual mailbox, ramping a dedicated sending IP or monitoring production mail. Those jobs need different setup and evidence.

Record the mailboxes and domains involved, how mail leaves the application and which sending IPs you control. Retain the existing warmup settings, schedules and reports. If production mail remains with a connected mailbox provider, keep that integration separate from a decision to send through Bird.

Warmy's sending guide describes two different setups: connected mailboxes use SMTP/IMAP or provider OAuth, while the separate Seed List product has you send from your existing email platform. Record which one you use. SMTP warmup goes through your mail server; moving the monitoring tool alone does not move that sender or its IP.

Keep any retained mailbox connection in its current account. Bird's Email API credentials do not replace a Google or Microsoft mailbox authorization.

Write down any mailbox activity that still needs a separate tool. Choosing a Bird monitoring workflow does not automatically recreate every action performed by the previous warmup process.

Verify the sending domain and enable tracking. Run a seed test using the production content and route you intend to evaluate. Record the pool, cohort, provider and reporting window, then inspect the observed inbox and spam results.

If you are also moving the sender to Bird, verify authentication and the send path first. Avoid combining a new sender, new audience and a sudden volume increase into the same test.

For a dedicated Bird IP, follow the dedicated-IP warmup guide and review delivery, deferrals and bounces as traffic increases. Retain the audience selection and suppression rules around the send.

For a mailbox that remains hosted elsewhere, evaluate its warmup requirements against that provider's sending setup. A sending-IP workflow does not transfer the mailbox's history or replace access to its account.

Assign the daily monitoring to the team operating the sender. Keep the old reports and record the date of each change to traffic or tooling. Investigate a regression using the actual sending records and a repeatable seed test before increasing volume again.
