Quick answer

In Winnr go to Email Users → Export, choose MailLead, click Export, then Download CSV. The file has each mailbox's address, password, full name and separate SMTP and IMAP login, password, server and port. Upload it with MailLead's bulk mailbox import, then set each mailbox's daily limit there.

Winnr provisions and warms the mailboxes; MailLead runs the campaigns.

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. 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. 2. Export in the MailLead format

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

  3. 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. 4. Add the mailboxes in MailLead

    In MailLead, use its bulk import for SMTP/IMAP mailboxes and upload the Winnr file.

  5. 5. Set limits and confirm

    The file has no daily-limit column, so set each mailbox's limit in MailLead. Check every mailbox connected before starting a campaign.

Frequently asked questions

What is in the MailLead file?

email, password, imap_login, imap_pwd, imap_server, imap_port, smtp_login, smtp_pwd, smtp_server, smtp_port and fullname. Both logins are the full email address and both passwords are the mailbox password.

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 MailLead'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 MailLead'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.
