When I send invoices using online solar accounts, they don’t find the destination email address. Invoices are not being received therefore not being paid.
Help.

Hi Nick,

Firstly click menu Tools > Email Status, and check that your emails are
being delivered successfully. If they are delivered then it may be marked
as spam by the recipient's email system - emails sent directly from Solar
Accounts come from an address like user.1234567@solaraccounts.co.uk. I
recommend you follow up with an email from your nick@ndaelectrical.co.uk
account asking the customer to look out for an email message from @
solaraccounts.co.uk - you should only need to do this once for each
customer. As a last resort you can export the invoice to a PDF file and
use your email program to send it.

Thanks.
But why would it be going through as spam?

Hi Nick,

We're not sure why it is marked as spam - unfortunately the email system of
recipients is outside our control.
