You can't. What you would need to do is filter the merge by 'sender' email address and combine that with the approach described in: https://www.msofficeforums.com/mail-...tml#post109253

Hi Macropod

Many thanks for the quick response. I'm not sure how this would help as my query is nothing to do with "email"; it's a standard business letter whereby head office can respond and just change the FROM address at the top of the letter.

Hi Macropod

Thanks for your quick response. I'm not sure how this helps, perhaps I need to clarify this is nothing to do with "email". I'm in Head Office and trying to respond to a client using our branch address of the client's area.

Your initial post implied a merge to email was being done. If that's not the case, and you're sending letters, you can use an IF field to test the Sender's addresses and vary the content in the letter accordingly. See, for example, Mailmerge String Testing in the Mailmerge Tips and Tricks thread at the top of this forum:

Apologies for delay in responding.

I've looked into your suggestion and seemed to have resolved my issue using a nested IF statement, similarly for the Branch signatory at the bottom of the letter.
