Can dynamic content blocks be A/B tested?

Yes, dynamic content blocks can be A/B tested, though the approach differs from static content testing:

Test the logic: Compare different personalization algorithms. Does recommendation engine A outperform recommendation engine B?

Test block presence: Does including dynamic content improve overall performance versus static alternatives?

Test block placement: Where in the email does dynamic content have the most impact?

Test personalization depth: Highly personalized blocks versus broadly relevant blocks.

Measurement considerations:

Track engagement with the dynamic block specifically (clicks on recommended products). Track overall email performance (total clicks, conversions). Analyze by segment since dynamic content may benefit some groups more than others.

Dynamic content tests are tests of algorithms and logic, not just content. They reveal whether your personalization engine actually helps.
