In Winnr go to Email Users → Export, choose ManyReach, click Export, then Download CSV. In ManyReach, open your mailbox settings and use the bulk import to add the file's mailboxes. The file sets a daily sending limit of 15 and leaves ManyReach's warmup off, so a mailbox Winnr warms is not warmed twice.
ManyReach is a cold-email platform built for high-volume outreach, with a unified inbox. Winnr provisions and warms the mailboxes; ManyReach runs the campaigns.
What's in the ManyReach file
Columns, in order: Email, First Name, Last Name, FromName, Signature, ReplyTo, SMTP Username, SMTP Password, SMTP Host, SMTP Port, IMAP Username, IMAP Password, IMAP Host, IMAP Port, Daily Sending Limit, Auto Increase Sends, Limit Increase Percentage, Maximum Sending Limit, Minimum Delay [min], Warmup Enabled, Warmup Limit, Auto Increase Warmups, Warmup Limit Increase [%], Maximum Warmup Limit, Reply Rate [%].
- 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.
- ReplyTo is left empty.
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 ManyReach format
Click Export, choose ManyReach 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. Review the sending and warmup columns
The file sets a daily sending limit of 15, with the same maximum so it does not ramp up, and leaves ManyReach's warmup off. If ManyReach does the warming instead of Winnr, change Warmup Enabled to TRUE.
-
5. Import into ManyReach
In ManyReach, go to the Mailboxes settings and use the bulk import option to add the mailboxes from the file.
-
6. Confirm every mailbox connected
Check that every mailbox shows as connected in ManyReach before launching a campaign.
Frequently asked questions
What does the ManyReach file pre-fill?
Daily Sending Limit 15 with a Maximum Sending Limit of 15 and Auto Increase Sends FALSE, Minimum Delay 11 minutes, Warmup Enabled FALSE with a Warmup Limit of 30 (auto-increasing by 15% up to 30) that only applies if you turn warmup on, and Reply Rate 50%. Signature is the mailbox's Winnr footer.
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 ManyReach afterwards.
Should I use ManyReach'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 ManyReach's warmup off so the mailbox is not warmed twice and stays at 50 emails a day or less in total. The export sets Warmup Enabled to FALSE; change it to TRUE only if ManyReach is doing the warming instead of Winnr.
Does ManyReach read replies over IMAP?
Yes. It pulls replies into its unified inbox over IMAP, and the Winnr export includes the IMAP fields.
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.
