Hi Heather,
Have you modified the Remittance layout in any way or do you use our standard version?
You can amend the text in the body of the email by selecting the Remittance layout > Edit.
In Report Designer select Report > Email Settings and you can change the wording in here. Also, please click on the To field and if you want it to send to the email address setup in the suppliers account, it should look like the below image.
If PURCHASE_DEL_ADDR.E_MAIL is written in the top box, remove it and click the bottom add button. In the expression editor, type PURCHASE_DEL_ADDR.E_MAIL > OK.
Once you've done this, click OK > File > Save > File > Exit. If save is greyed out, select Save As and save as a new layout. Ensure you use the new layout from now on.
