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. The file also sets a daily sending limit of 15 and a 600 to 1200 second wait between sends.
Woodpecker is an outbound-email tool with per-mailbox sending controls and reply detection. Winnr provisions and warms the mailboxes; Woodpecker runs the sequences.

Check before you upload
- Three tracking-domain columns. All three hold the bare sending domain. Replace them with your tracking hostname (add the CNAME in Winnr) or clear them. A domain that does not point at Woodpecker's tracking breaks open, click or unsubscribe tracking.
- Footer. Usually empty. Add your signature in Woodpecker or fill the column.
- Bcc. Empty. Fill it only if you copy sends to a CRM address.
Daily limit in Woodpecker
Woodpecker takes the per-mailbox cap from Daily sending limit, pre-filled with 15, and paces sends with the wait-time columns. Keep cold sending at 10 to 20 per mailbox per day and each mailbox's total, cold plus warming, at 50 or under. Warm new mailboxes for at least two weeks before they send cold.
What's next
Step-by-step
-
1. Select the mailboxes in Winnr
Open Email Users and tick the mailboxes you want in Woodpecker. To take one domain, filter by it and tick the header checkbox. With nothing ticked, the export includes every mailbox in your account.
-
2. Export in the Woodpecker format
Click Export, choose Woodpecker under Export Format (the search box finds it quickly), then click the Export button.
-
3. Download the CSV
Click Download CSV. The link lasts 15 minutes, so export again if it has expired. The file holds 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
Why are the tracking domains set to my sending domain?
Winnr fills all three with the mailbox's own domain as a starting value. Tracking only works on a hostname that points at Woodpecker's tracking, so set up a tracking CNAME and put that hostname in, or clear the columns.
What do Sending wait time from and to mean?
The gap between two sends from the same mailbox, from 600 to 1200 seconds (10 to 20 minutes). At 15 a day that spreads sending over roughly two and a half to five hours.
Why is there no IMAP login column?
Woodpecker's layout has IMAP email instead, which Winnr fills with the full address. That is the IMAP login for a Winnr mailbox.
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. The file has no warmup column, so check the setting after import.
Woodpecker's connection test fails for a mailbox. What now?
Check SMTP password and IMAP password for that row. A password changed in Winnr after you exported will not match the file. Export that mailbox again and re-add it. If a fresh export still fails, see the mailbox authentication troubleshooting guide.
