# Message A/B Testing

## Objective

Try out two different subject lines in a message to see which one achieves the best open rate. A/B testing is very easy to carry out with a scheduled Whiteboard. Multiple versions of a message are sent to a percentage of a group and the most popular version is then sent to the rest of the group.

## Prerequisites

Before you build the whiteboard, make sure you create the following in Mapp Engage:

- a segment that contains contacts who opted in to receive email communication from you
- two prepared messages with different message titles for testing

## Whiteboard

The sendout starts at noon. Two versions of the message are each sent to a different 10% of recipients randomly selected from the whiteboard audience. The main message is the one that has the higher opening rate and is sent to the remaining 80% of the audience after a two-day wait period.

**Show detailed configuration**

1. Configure the start job **Whiteboard Audience** by defining the date, time, Group and if needed, the segment. ![](https://cdn.document360.io/554b9b98-6720-4d8b-9919-c7b203d72648/Images/Documentation/4bf2c93a-98ed-4645-8102-e56db43effb6.png)
2. Add the job **Split Email Sendout**.
  - Select the **Test message 1** and **Test message 2** from the drop-down list.
  - Define the **Message selection criterion** of the main message.
  - Define the **Sendout delay**- the time that will pass between the test sendout and the main sendout. ![](https://cdn.document360.io/554b9b98-6720-4d8b-9919-c7b203d72648/Images/Documentation/4f3e5d81-de3a-4f93-9a7c-1e77acb2f1d8.png)

Build additional steps of the Whiteboard if needed.
