I'm looking for a solution to send file upload as email attachment. I found the below related link to achieve it. 

https://www.vegaitsourcing.co.uk/media-center/blog/how-to-send-an-email-with-attachments-using-episerver-forms 

I followed the same steps as given in this link but it's not working. model returns null value for some reason after form submission. I feel like i'm missing something to have the form submission value in the model. 

Could you please advise me on this to know what i'm missing here to get he model value, otherwise is there an other better approach to send file upload as email attachments.

also using this solution will cause any performance issue for the site ?  

IEnumerable<EmailTemplateActorModel> model = this.Model as IEnumerable<EmailTemplateActorModel>;

I'm using Epi forms version 4.25.1.0

Epi DXC version 11.8.1.0
