Setting up a 3x5 survey with embedded data/Branch Logic

Hi there,
I need to set up a survey which will have 15 iterations (3x5 design). The suggestion has been to use Branch Logic with Embedded data (still learning what these terms mean 😅).
The survey will open up with an email where I need to change the "Sender" name (3 variations). The Sender name has also been placed into some of the questions.
In addition, some of the questions/text will also have another variable (with 5 variations).
I will be launching the survey to ~1,500 people (~100 people per version). Are there resources on how I can set up a single survey that would allow each variation to be sent to a different cohort of people (same demographic throughout the ~1,500 participants).
I'm not sure if this is relevant, but I will be using Prolific to launch the survey and find participants.
Thank you!

You are correct, embedded data and branch logic are best.
Here is a simple example: lets say you want to survey men and women about their opinions on vehicles (cars vs. trucks) in different colors (red vs. yellow). This is a 2 x 2 design with 2 cohorts (men vs. women). Lets say you want to ask people how much they agree with the statement "I like my [car/truck] in the color [red/yellow]". You can use embedded data to randomly assign an attribute to vehicle and to color. (Do this in the survey flow, see https://www.qualtrics.com/support/survey-platform/survey-module/survey-flow/standard-elements/embedded-data/.) If you want this randomization to occur independently for men and women, you first need to capture gender and then branch based on gender before doing your randomization (also in the survey flow, see https://www.qualtrics.com/support/survey-platform/survey-module/survey-flow/standard-elements/branch-logic/).
Step 1: Capture demographic variables (might be passed via prolific, or captured on an introductory page)
Step 2: Branch based on demographic variables (in survey flow)
Step 3: Randomly assign conditions within demographic variable branches. (in survey flow)
