Segmenting Contacts

Segments are similar to contact lists, except they update dynamically over time as information stored about your contacts or the criteria used to define your segments changes. When you segment your audience, you are able to create personalized Automation emails and Single Sends that directly address the wants and needs of your particular audience.

The Marketing Campaigns Segments API allows you to create, edit, and delete segments as well as retrieve a list of segments or an individual segment by ID.

Note that Twilio SendGrid checks for newly added or modified contacts who meet a segment's criteria on an hourly schedule. Only existing contacts who meet a segment's criteria will be included in the segment searches within 15 minutes.

Segments built using engagement data such as "was sent" or "clicked" will take approximately 30 minutes to begin populating.

Segment samples and counts are refreshed approximately once per hour; they do not update immediately. If no contacts are added to or removed from a segment since the last refresh, the sample and UI count displayed will be refreshed at increasing time intervals with a maximum sample and count refresh delay of 24 hours.

For more information on creating segments with the Twilio SendGrid Marketing Campaigns UI see "Segmenting your Contacts."

For help with Segmentation Query Language, see our Segmentation Query Language reference

Delete Segment

DELETE /marketing/segments/{segment_id}

This endpoint allows you to delete a segment by segment_id.

Note that deleting a segment does not delete the contacts associated with the segment by default. Contacts associated with a deleted segment will remain in your list of all contacts and any other segments they belong to.
