There are a couple different scenarios which could result in an e-mail with a document not arriving in Hubdoc.
- The unique intake email is missing the "@app.hubdoc.com" ending.
- The format sent to Hubdoc's unique email intake is not a PDF or an image file.
- An error message is attached to the email which is sent back outlining a more precise cause.
Ensuring these three things are completed will almost always mean that your documents will end up in Hubdoc!
If you are using a middleware email forwarding service, in rare cases, Hubdoc will return an error message to your email domain because it believes the email sender is a spammer. Middleware software may block Hubdoc's domain from future emails.
To resolve this issue please look for a 'White List' option and input the unique email intake “_________ @app.hubdoc.com” email address into the whitelist field. For more information about white listing email addresses, please see this article from SendGrid on how to complete this: https://sendgrid.com/docs/User_Guide/Settings/mail.html
