Dear Martin (and Lance, Daniel and Francis for the attachment code).

Thank you so much this!

It has not only solved my problem with much less work that I had expected, but also introduced me to the power of Gsuite apps.

When I use this for real I am going to need to sent out around 500 e-mails. Do you know if the system will cope with this, or will I have to split it up into batches?

Thank you for any advice
