well as Teodor said that you can’t have repeats in mail body, it is simple to solve with a “variable” or by just joining all the query field records with a formatter
Variable - do a manual append
- define a variable before the query with Set Variable step and give it empty value
- do the query
- repeat througth the query and as sub steps:
- just mutate the variable with Set Variable but just append new values
Use a join formatter
- this one is very simple, right after the query do Set Variable and give it as value formatter join string with the record fields
As last step to both solutions - just use the variable in your mail body
Hope it is a bit clear
