In Winnr go to Email Users → Export, choose Woodpecker, click Export, then Download CSV. In Woodpecker, add email accounts through the SMTP/IMAP connection and choose its option to add them in bulk, using the file's values. Check the three tracking-domain columns first: they are filled with each mailbox's own domain.
Woodpecker is an outbound-email tool with per-mailbox sending controls and reply detection. Winnr provisions and warms the mailboxes; Woodpecker runs the sequences.
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.

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 Woodpecker format
Click Export, choose Woodpecker 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. Check tracking domains and limits
The Open, Click and Unsubscribe tracking domain columns are filled with each mailbox's domain. Change them to the tracking domain you set up, or clear them. The file also sets a daily sending limit of 15, the recommended cold-sending default.
-
5. Add the mailboxes in Woodpecker
In Woodpecker, add email accounts, choose the SMTP/IMAP connection and its add-in-bulk option, and provide the values from the Winnr file.
-
6. Confirm every mailbox connected
Woodpecker tests SMTP and IMAP for each mailbox. Check every mailbox connected before assigning it to a campaign.
Frequently asked questions
What is in the Woodpecker file?
SMTP email, SMTP login, SMTP password, SMTP server, SMTP port, SMTP from name, IMAP email, IMAP password, IMAP server, IMAP port, Footer, Bcc, Open tracking domain, Click tracking domain, Unsubscribe tracking domain, Sending wait time from, Sending wait time to and Daily sending limit. The wait time is 600 to 1200 and the daily limit is 15.
What daily limit does the file set?
The Daily sending 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 Woodpecker afterwards.
Does Woodpecker read replies over IMAP?
Yes. Woodpecker needs IMAP to detect replies and pause sequences, and the Winnr export includes the IMAP fields.
Should I use Woodpecker'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 Woodpecker'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.
