Only thing I would bring up on this because I did do a mailshot last week for the 2 QS’s.
When sending it out, we only get the option to send it to ‘main contact’ or ‘All contacts’ of a business. So for example if we knew the DM/ correct contact at Client A wasn’t listed as the main contact, we’d have to select ‘all contacts’ but then we’d potentially risk sending the email to a lot of the wrong people.
From experience I’d suggest it should be more targeted than either one person who may not be correct or everyone where we know for a fact some people won’t be correct.
