Hi @smallears613: - Create a new (template) email - Specify internal name, subject and content - Click Save & Close - In email detail dropdown, click Add A/B Test - Change subject and content in the edit view - Click Save & Close again Now you can switch between the email variants and send test emails - they are delivered with different subject lines. ---

Yes, after hitting “Add A/B Test” you are in variant B. Just hit “Save & Close” again, then you are prompted the missing fields for your variant email (you have to - again - select your email type, which is kind of strange). After you edited variant B you can toggle between the variants at the bottom of the read-only email detail screen. ---

(A/B tests do not only consist of a section, but the email is basically duplicated and every field can be modified) ---

> [@petertl](#): > > Create a new (template) email Is A/B testing of emails limited to **template** emails? I’m looking for a way to A/B test an email that needs to be sent from a campaign and I don’t find the option to do that. Is it impossible to do A/B test with email campaigns?
