# Create an A/B campaign

An A/B testing campaign is an email campaign that lets you test two different versions of the same campaign on part of your mailing list and then automatically send the version that performed better to the rest of the recipients on your list. A/B campaigns help you test the subject line, campaign content, and/or campaign senders.

To create an A/B testing campaign:

1. On the menu bar, click **Campaigns**.
2. In the top right-hand corner, click **New** > **A/B testing**.
3. On the **Set Basic Settings** page, you can now create different versions for the following:

    ![Set Basic Settings page for an A/B testing campaign](https://doc.sitecore.com/api/markdown-image/send/en/users/sitecore-send/images/Create_AB_Send.png)

    - **Subject line** - test what is the best title for your campaign. Both Subject A and Subject B will be tested on a percentage of your list.
    - **Content** - test two different HTML files, that can contain different text, different images, and so on.
    - **From name** - test which sender name receives the most responses. For example, you can learn whether your recipients prefer the sender to have a person's name or the company's name.

    To continue to the next page, click **Next**.

4. On the **Choose email list** page, select one or more email lists, or [segment(s)](https://doc.sitecore.com/send/en/users/sitecore-send/email-lists/use-segments-to-create-targeted-campaigns.html "Use segments to create targeted campaigns") of an email list that contains at least 3 recipients and click **Next**.
5. On the **Design** page, edit your campaign design and click **Next**. You can:
    - Click **Start designing** to create your own design from scratch by using the [campaign editor](https://doc.sitecore.com/send/en/users/sitecore-send/campaigns/working-with-the-campaign-editor.html "Working with the campaign editor"). You can select a premade, customizable [template](https://doc.sitecore.com/send/en/users/sitecore-send/campaigns/working-with-the-campaign-editor/work-with-the-newsletter-template-library.html "Work with the newsletter template library").
    - Toggle the **Imported campaign template** switch to *On* to [import a campaign](https://doc.sitecore.com/send/en/users/sitecore-send/campaigns/work-with-campaigns/import-a-campaign.html "Import a campaign") using an existing campaign template from a URL or your computer, or by pasting HTML code.
6. On the **Set AB Settings** page, you can define which part of your email list will act as a test group. The recipients in the test group receive the different campaign versions and, based on how they react, the winning version is defined and this version is sent to the winning group (the rest of the email list).

    Drag the slider to determine how many recipients are in **Group A**, **Group B**, and the **Winning group**.

7. In the **Which winning version will be sent to the rest of your list** section, select one of the two following check boxes:
    - The one with the highest numbers of unique opens.
    - The one with the highest number of unique clicks.
8. In the **Run the test for** section, use the slider to set the duration of the test. Click **Next**.

    > [!note]
    > The maximum duration of the test is 24 hours. The minimum is 1 hour.

9. On the **Schedule delivery** page, plan when the campaign is sent out and click **Next**.

    > [!warning]
    > When you set the time, you must check the time zone in your account settings. For example, if you send your campaign at `16:00` and, in your account, your time zone is set to GMT+1, your campaign will be sent out at `17:00`.

    You can also scroll down to the **Resend campaign to non-openers** option and toggle it to **Yes** to resend the email message again to people who do not open it after a certain amount of time.

10. On the **Preview** page, review the overview of your A/B campaign. To edit a setting, click the *Edit*  link. Any fields with missing information are indicated by ![RedCrossInCircle.png](https://doc.sitecore.com/api/markdown-image/send/en/users/sitecore-send/images/RedCrossInCircle.png).

    When you are finished, you can either click **Send** to send your campaign, or you can save your changes for later by clicking **Save & exit**.
