Email Users → Export → Reply.io. Winnr downloads a CSV with each mailbox's SMTP and IMAP credentials in Reply's format. In Reply, go to Email Accounts, click Add Mailbox (top right) and choose Import from CSV, then upload the file. Every mailbox connects and attaches to your campaigns, usually within a couple of minutes.
Reply.io is a multichannel sales-engagement platform (email, LinkedIn, calls) with a consolidated inbox. Winnr provisions and warms the mailboxes; Reply drives the outreach.

Frequently asked questions
Where exactly is the import in Reply?
Email Accounts → Add Mailbox (top right) → Import from CSV. Reply reads the SMTP and IMAP columns straight from the Winnr export.
Does Reply support SMTP or OAuth?
Both. Winnr mailboxes connect over SMTP/IMAP, which is what the CSV import uses — no OAuth needed.
Does Reply read replies over IMAP?
Yes. Reply pulls replies into its consolidated inbox using the IMAP credentials, and multichannel steps (email plus LinkedIn and calls) use the same mailbox for the email leg.
Reply's CSV has warm-up columns — do I need them?
They're optional. You can set Reply's warm-up per row, but if you're already warming on Winnr ($0.60/mailbox/month), leave those out to avoid double warming.
