Set email sender in Landing Page via AMPScript

Question

I'm sending out on email when a user lands on a landing page, described in this post.

Now I would like to change the sender dynamically based on certain conditions. To do this I created a sender profile which uses variables in the FromEmail and FromName fields. Unfortunately tho, this seems to be ignored.

Sample from the landing page:

set @SenderEmail = Lookup('Ent.sender_DE', 'SenderEmail', 'parameter', @param)

And in the delivery profile settings I simply use this variable like so: <br>
%%=v(@SenderEmail)=%%

What am I missing to make it work? Or is there another way to simply set the sender via AMPScript in the landing page?

Answer 1

I managed to get it working simply by adding the field sender email field into the Data Extension the triggered send uses. After that instead of specifying the sender as %%=v(@SenderEmail)=%% I did it with the following syntax %%SenderEmail%% and it started working.

Still unclear for me tho, how can I use a variable in those fields unless it's not par of the underlying DE.

It was providing the default from name and email address on your emails because the AMPscript variable was empty. Your issue is that you need the variable defined in the email, not just on the landing page for the dynamic sender profile to work. The dynamic sender profile pulls from the emails AMPscript, not the landing page.

The only way to control the from name directly from the Landing page is via a triggered send API call, in which case you can define the from name and address in the API call.

Alternatively, you can pass the variable into the email or have the lookup inside the email itself which should fill the AMPscript variable call you have in the sender profile.
