In Winnr go to Email Users → Export, choose Snov, click Export, then Download CSV. In Snov.io, open your email-account settings and choose the import from CSV option, then upload the file. Snov takes up to 100 accounts per file and rejects renamed or reordered columns, so export in batches of 100 and only edit values.
Snov.io is a sales-prospecting and email-outreach platform with a built-in CRM and a unified inbox. Winnr provisions and warms the mailboxes; Snov handles prospecting and campaigns.

Check before you upload
- Batch size. 100 accounts per file at most. Count your ticked rows before exporting.
- Headers are fixed. Snov matches columns by exact name and position. Change values only.
- reply_to_email. Empty, so replies go to the sending address. Fill it only if replies should go elsewhere.
- Encryption. Leave both encryption types at SSL. Ports 465 and 993 only accept SSL connections.
Daily limit in Snov
Snov reads the per-account limit from Daily sending limit, pre-filled with 15. 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 up to 100 mailboxes in Winnr
Open Email Users and tick up to 100 mailboxes. Snov accepts at most 100 accounts per import, and with nothing ticked Winnr exports every mailbox in your account, which can be more than that.
-
2. Export in the Snov format
Click Export, choose Snov 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. Import from CSV
In Snov.io, open your email-account settings, choose the import from CSV option and upload the file. Do not rename, reorder or delete columns.
-
5. Repeat for the next batch
Tick the next 100 mailboxes in Winnr, export again and import that file, until every mailbox is in Snov.
-
6. Confirm every mailbox connected
Check every account shows as connected before adding it to a campaign.
Frequently asked questions
How many mailboxes can I import per file?
Snov caps CSV import at 100 email accounts per file. Split larger selections into batches of 100 and export each one separately.
What does Delay between emails 660 mean?
Snov waits 660 seconds (11 minutes) between sends from the same mailbox. At 15 a day that spreads sending over roughly two and a half hours.
Can I change the daily limit in the file?
Yes, but edit only the value in the Daily sending limit column, not its header. Snov rejects files whose columns were renamed or moved.
Should I use Snov'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 Snov's warmup off so the mailbox is not warmed twice. The file has no warmup column, so check the setting after import.
Does Snov read replies over IMAP?
Yes. Snov uses IMAP to sync replies and campaign stats, and the file includes the IMAP host, port, username and password.
Snov says an account could not connect. What now?
Check 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 import it on its own. If a fresh export still fails, see the mailbox authentication troubleshooting guide.
