How can we include a PDF file that can be downloaded by the respondent?

We have a donation form and the client has asked that we be able to include an option for the donor that has corporate matching by their employer. 

Any suggestions?

Hello @JFedGMW - Can you give more details on what you meant by "include an option for the donor that has corporate matching by their employer"?

What does this option do? Are you hoping to apply conditions to your form?

I was wondering what other non-profits do. My recollection, having worked for a for-profit that did matching, was that you needed to present a receipt to the employer for them to match or complete one of the employer's forms. It would seem that we should use the "attach a PDF" feature in the autoresponse so that the donor could take that and present it to the employer. 

My reason for posting this was just to see what the experts (you) had to say. Thanks for the help.

It would seem that we should use the "attach a PDF" feature in the autoresponse so that the donor could take that and present it to the employer.

If your aim is to present a receipt (which I assume comes in a PDF format), instead of using the PDF ATTACHMENT option on the AUTORESPONDER email, use the ATTACH A FILE option.

The PDF ATTACHMENT feature will only include a PDF copy of their submitted data.

Another approach you can try is to add the PDF file straight on your form, or on your form's THANK YOU PAGE. This way, your users will be able to download it either before or after form submission.
