How can I send an email to a specific number of contacts from a larger segment in Pushwoosh?

If you need to send an email to a specific number of contacts (e.g., 2000) from a larger segment in Pushwoosh, you can use one of the following approaches:

Manual selection (exact count)

1. Export the entire segment to a spreadsheet.
2. Use a spreadsheet editor or a script to randomly select the desired number of contacts (e.g., 2000).
3. Import that shorter list back into Pushwoosh as a new segment: go to Audience → Segments, click Create Segment and choose Import segment. The CSV must contain User IDs or HWIDs already registered in your project (unregistered identifiers are skipped) and be smaller than 100 MB. Details: Import a segment.
4. Send the email to that imported segment.

Percentage split in a Customer Journey (approximate count)

If you know the total size of the segment, add the A/B/n Split flow-control element to a Customer Journey and route only a percentage of users to the branch that sends the email. For example, with 40,000 devices in the segment, a 5% branch yields roughly 2000 recipients.

Notes on this method:

• The element supports up to 4 branches and the percentages must add up to 100%.
• It gives no precise control over the exact number of contacts, because the result depends on the current segment size.
• See A/B/n Split for configuration steps.
