I am trying to send the invoices to my customers but first I am checking with a demo customer if the mails arrive, unfortunately they are not arriving and I am not able to deliver the invoices to the customers.
I don’t know what you mean by the queue in .env,I have set everything as it is on the help page,I have enabled smtp senders in Google Workspaces and added the IP addresses to the Google Workspace whitelist however,Invoice Ninja tells me " the email was sent successfully" but it doesn’t reach the final email where the invoice should arrive.
That means the queue is enabled. To start I suggest changing it to sync to disable the queue. If it works without the queue there’s info here to enable it.
I don’t see any error in the file you mention, I don’t know what could be wrong because I have done all the configuration following the steps in the faqs of the web and it still doesn’t work.
