In Winnr go to Email Users → Export, choose Instantly, click Export, then Download CSV. In Instantly, add new email accounts, pick the option for any SMTP/IMAP provider and use its bulk CSV import to upload the file. The file sets a 15-a-day campaign limit and leaves Instantly's warmup off, so a mailbox Winnr warms is not warmed twice.
Instantly is a cold-email sequencer with campaigns, a unified inbox and its own warmup. Winnr provisions and warms the mailboxes; Instantly runs the campaigns.
What's in the Instantly file
Columns, in order: Email, First Name, Last Name, IMAP Username, IMAP Password, IMAP Host, IMAP Port, SMTP Username, SMTP Password, SMTP Host, SMTP Port, Daily Limit, Warmup Enabled, Warmup Limit, Warmup Increment.
- First Name and Last Name come from the mailbox's display name.
- SMTP uses port 465 and IMAP port 993, both over SSL. The username is the full email address and one password covers SMTP and IMAP.
- Daily Limit is 15. Warmup is off; if you turn it on, it runs at up to 35 a day.
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 Instantly format
Click Export, choose Instantly 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. Decide on warmup
The file sets Warmup Enabled to FALSE, so the mailbox is not warmed twice. If Instantly does the warming instead of Winnr, change that column to TRUE before uploading, or turn Instantly's warmup on after import.
-
5. Upload to Instantly
In Instantly, go to Email Accounts, add new accounts, choose the any-provider (SMTP/IMAP) option and use the bulk CSV import to upload the file.
-
6. Confirm every mailbox connected
Instantly tests SMTP and IMAP for each account. Check every mailbox shows as connected before adding it to a campaign.
Frequently asked questions
What does the Instantly file pre-fill?
Daily Limit 15, Warmup Enabled FALSE, Warmup Limit 35 and Warmup Increment 1. The warmup values only apply if you turn Instantly's warmup on, and then keep a mailbox at 50 a day in total. Change these columns before upload if you want different values.
Should I use Instantly'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 Instantly's warmup off so the mailbox is not warmed twice and stays at 50 emails a day or less in total. The export leaves Instantly's warmup off; set Warmup Enabled to TRUE only if Instantly is doing the warming instead of Winnr.
Is there a limit on how many accounts one file can hold?
Instantly may cap how many accounts or how large a file one bulk import accepts. If the upload is refused for size, export smaller selections from Winnr and upload them one at a time.
Does sending through Instantly use my Winnr dedicated IP?
Yes. Instantly hands each message to the Winnr SMTP host in the file, so it goes out the same way as any other mail from your Winnr mailboxes, including through a dedicated IP if one is set up on your account.
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.
