Workflow emails to outside of domain email addresses are flagged as SPAM

[dpavlov]

Hello,

so we use AppSheet to generate invoices and send them as PDF attachment. We send around 200 per month. 

A lot of these email are laning in the recipients SPAM folders. 

We use Google Workspace and all our recipients use Google Workspace as well. 

How can we fix that?

I think that there is no way.

Are using the default noreply@appsheet.com as the sender address? 
In that case, you might instruct your respective Workspace admins to add this email to the Approved Senders List.
