I'm sending to a big list and it has groups of users set up as Data Extensions. I want to do some dynamic content at time of send based on if the user is in a particular Data Extension. There is some overlap but I can deal with that with if/else. I was thinking of doing something like this:
%%[ IF UserIsInDataExtension("London_users") THEN ]%% (Content for London segment) %%[ ELSEIF UserIsInDataExtension("Birmingham_users")]%$ (Content for Birmingham segment) %%[ ELSEIF UserIsInDataExtension("Never_purchased")]%% (Content for Never purchased segment) %%[ELSE]%% (default content) %%[ END ]%%
Is there something like this in AMPScript , and if there's nothing exactly like this then can I do something which attempts a lookup from the Data Extension as a way of seeing if the user is in it?
