The fastest path is Winnr's direct sync: Settings → Tools → EmailBison → "Sync Emails" pushes your mailboxes straight into EmailBison with no file handling. If you'd rather use a file, go to Email Users → Export → EmailBison for a CSV in EmailBison's bulk-import layout, then in EmailBison open Email Accounts → bulk import and upload it. Either way every mailbox lands ready for campaigns, usually within a few minutes.
EmailBison is a private cold-email sequencer aimed at high-volume senders and agencies, with a unified master inbox for reply management. Winnr provisions and warms the mailboxes; EmailBison runs the campaigns.
What's next
Step-by-step
-
1. Filter to the mailboxes you want to export
Open the Email Users page in Winnr. Filter by domain, tag, or warming status to narrow to just the mailboxes for this campaign.
-
2. Click Export → EmailBison
Hit Export and pick EmailBison. Winnr builds a CSV in EmailBison's bulk-import layout, with SMTP and IMAP host, port, username, and password columns already mapped.
-
3. Open EmailBison
Log into EmailBison and go to Email Accounts (Senders). This is where all your sending mailboxes are managed.
-
4. Bulk import the CSV
Choose the bulk inbox import option and upload the Winnr CSV. Because Winnr mailboxes use standard SMTP/IMAP, they import directly without the Google/Microsoft captcha dance.
-
5. Verify connection status
EmailBison validates each mailbox and marks it connected. Confirm every row shows a green/connected status before assigning them to a campaign.
Frequently asked questions
Should I use the direct sync or the CSV?
Direct sync (Settings → Tools → EmailBison → "Sync Emails") is faster and skips file handling, so use it when you can. The CSV export is the fallback if you're loading into a separate EmailBison workspace or want to review the file first.
Does EmailBison read replies from Winnr mailboxes?
Yes. EmailBison connects over IMAP and pulls replies into its unified master inbox, so responses from your Winnr mailboxes all land there.
Should I warm on Winnr before importing to EmailBison?
Yes. Run Winnr's built-in warming ($0.60/mailbox/month) until reputation is established, then import. New mailboxes should not jump straight to cold volume.
Do Winnr mailboxes need OAuth or app passwords?
No. Winnr mailboxes connect over standard SMTP/IMAP, so EmailBison's bulk CSV import handles them directly — no OAuth flow and no app-password captchas.
