Test email in invoices not working

Hi Allyson,

We’re not naturally supporting SparkPost, we’ve got our own delivery-system built in (see guide: https://zerobscrm.com/kb/knowledge-base/mail-delivery-method-setup-smtp/)

If it’s working on one but not the other, perhaps there’s a bug there though. Does this persist if you set up SMTP via our wizard (and disable SparkPost?) In future please direct questions to the support ticket system here: https://zerobscrm.com/kb/submit-a-ticket/ (this helps us better manage support).

All the best
Woody
