In Winnr go to Email Users → Export, choose AiCloser, click Export, then Download CSV. The file has an inbox name, the address, first and last name, and SMTP and IMAP host, port, username and password for each mailbox. Upload it with AiCloser's inbox import, then set each mailbox's daily limit there.
AiCloser is an AI outreach tool for one-to-one email conversations. Winnr provisions and warms the mailboxes; AiCloser runs 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 AiCloser format
Click Export, choose AiCloser 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 is short-lived, so if it has expired just run the export again. The file holds mailbox passwords in plain text, so keep it private.
-
4. Add the inboxes in AiCloser
In AiCloser, use its import for SMTP/IMAP inboxes and upload the Winnr file.
-
5. Set limits and confirm
The file has no daily-limit column, so set each inbox's limit in AiCloser. Check every inbox connected before starting outreach.
Frequently asked questions
What is in the AiCloser file?
inbox_name, email, first_name, last_name, imap_host, imap_port, imap_username, imap_password, smtp_host, smtp_port, smtp_username and smtp_password. inbox_name is the mailbox's display name.
What daily limit should I set?
10 to 20 cold emails per mailbox per day (15 is a good default), and 50 or under in total including warming.
Should I use AiCloser'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 AiCloser's warmup off so the mailbox is not warmed twice and stays at 50 emails a day or less in total.
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.
