Is it possible to email all my customers in one go to let them know I am changing banks and send them my New Bank Account Details?

Hi John,

Solar Accounts doesn't have a way to email customers in bulk. The simplest
approach would be to export your Customers list to a spreadsheet, then open
the spreadsheet and copy the email addresses to the BCC field in your email
program. (Note: do not use the CC or TO field because then each
customer can see the email address of each other customer)

Thanks Mark
