Solutions / Audience segmentation

Send the right email to the right people

Slice any list with simple condition rules and send each group an email that fits. Better targeting means more opens, more clicks and fewer unsubscribes.

At a glance

Segments work with campaigns, autoresponders and A/B tests.

Overview

One list, many audiences

Sending the same email to everyone is the fastest way to lose subscribers. A customer in Pune does not need your Delhi store offer, and a free user should not get a renewal reminder.

GO MAILBOX lets you store any detail as a custom field, from city and signup source to plan type or last purchase. Then build segments with simple rules and send each one the message that matters to them.

FAQ

Segmentation questions

Segmentation FAQ

  • What is a segment?

    A segment is a slice of a list that matches rules you set, such as city, signup date or a custom field like plan type.

  • Do segments update on their own?

    Yes. Segments are rule-based, so new contacts who match the rules are included automatically at send time.

  • Can I import custom fields?

    Yes. Map any column in your CSV to a custom field during import and use it in segments and personalisation.
