Mainflow now includes an exciting new feature—Conditional Content Blocks! This allows you to personalize emails by sending specific content to different groups of subscribers. Instead of creating multiple emails, you can design one email that dynamically displays relevant information based on conditions you set.
Similar to other content blocks, the Conditional Section allows you to group content into sections and apply conditions to them. These conditions determine what content is shown when the email is sent.
Conditional blocks work with tags to define which recipients see specific sections. To learn more about tags, check out the Segmentation Guide.
To apply this feature, Add a Conditional Section to the email content. You will then be able to set the condition to either Show IF in Selected Tag or Show IF NOT in Selected Tag see something similar to the below screenshot where 3 sections are used and set to show for 3 different tags. This email will generate content in such a way that only the Tag AAA users will see the 1st conditional section. The same applies to the rest of the 2 conditional sections.

Once you sent the email as an Email Campaign, you will then be able to see the actual email that was generated and delivered to the recipients as below:


Remember that, The Conditional Sections do not support nesting. You can add one single block to each conditional block from any of the Text, Media, Design, or Widget Blocks.
