In Winnr go to Email Users → Export, choose Reply.io, click Export, then Download CSV. In Reply, go to Email Accounts, add a mailbox and choose the import from CSV option, then upload the file. The file sets a daily limit of 15 cold emails, the recommended default.
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.
Sending limits
Keep cold sending at 10 to 20 emails per mailbox per day (15 is a good default), and keep each mailbox's total, cold plus warming, at 50 or under. Warm new mailboxes for at least two weeks before they send cold, and longer on a brand-new domain.
What's next
Step-by-step
-
1. Select the mailboxes in Winnr
Open Email Users and tick the mailboxes you want for this campaign. Search or the Domain filter help you find them. If nothing is ticked, the export includes every mailbox in your account.

2. Export in the Reply.io format
Click Export, choose Reply.io under Export Format (type in the search box to find it quickly), then click the Export button.

3. Download the CSV
Click Download CSV as soon as it appears. The link expires after 15 minutes, so if it has expired just run the export again. The file holds mailbox passwords in plain text, so keep it private.

4. Import from CSV
In Reply, go to Email Accounts, add a mailbox and choose the import from CSV option, then upload the Winnr file.

5. Confirm every mailbox connected
Check every mailbox shows as connected, then attach the mailboxes to a sequence.
Frequently asked questions
What is in the Reply.io file?
Email, Daily Limit, Sender Name, SMTP Host, SMTP Port, SMTP Password, SMTP SSL (Optional), IMAP Host, IMAP Port, IMAP Password and IMAP SSL (Optional). Daily Limit is 15 and both SSL columns are TRUE. The email address doubles as the login.
What daily limit does the file set?
The Daily Limit column is pre-filled with 15, the recommended cold-sending default. Keep cold campaigns at 10 to 20 per mailbox per day and each mailbox's total, cold plus warming, at 50 or under. Change it before you import, or in Reply afterwards.
Do Winnr mailboxes need OAuth in Reply?
No. They connect over SMTP and IMAP with the address and password in the file.
Should I use Reply's warmup or Winnr's?
Pick one per mailbox. Winnr's built-in warming is $0.60 per mailbox per month; if you use it, keep Reply's warmup off so the mailbox is not warmed twice and stays at 50 emails a day or less in total. The Winnr export does not include any warm-up columns.
What connection settings are in the file?
Each row carries that mailbox's own SMTP host (port 465, SSL) and IMAP host (port 993, SSL). The username is the full email address, and the same password works for SMTP and IMAP. Mailboxes on different domains can use different hosts, so keep the values from each row rather than copying one host across every mailbox.
Some mailboxes failed to connect. What now?
The usual cause is an old password: a password changed in Winnr after the export will not match the file. Export those mailboxes again and re-import them. If a fresh export still fails, see the mailbox authentication troubleshooting guide.
