# Add Individuals to an Email List

> This endpoint places a message on a queue and will return an Accepted response. 
The message will then be picked up by the queue and process adding individuals to a list.
Note that this could take up to 4 hours to be completed. Do not use this endpoint to add a single individual to a list, wait and do them in bulk instead. 
Doing a single individual at a time will block up the organizations queue and will increase processing time.
To retrieve individual id's, use the api/ContactIndividual/Query.
