Your invoices are sent by us and delivered to your customers from the email address invoices@mail.billdu.com with your company name first.
In the email message by clicking on the blue View invoice button a window opens, where your customer can see the invoice, download it, mark it as paid, pay it (if you've enabled online payments), create a cash receipt and much more.
If for some reason your customer doesn't see the invoice, by clicking on "Click here to download PDF" in the email message a PDF file will be downloaded.
The email communication between you and your customer can be found also in the Inbox.

Own email address/SMTP
Billdu enables to send emails from your own email address by using SMTP. You will need to know your exact SMTP mail settings. Contact your mail administrator or consult the documentation to your email client.
Note: It's not possible to use Inbox or get replies to your messages with this setting. The Inbox works only with Billdu's mailing system.
Note: When you use the SMTP method to send emails, invoices and other documents will be sent as PDF attachments.
How to set up your email address:
Navigate to Settings – Document Settings – Email settings
As an Email sending method choose SMTP
Enter your Login (mostly email address), password, SMTP server address, port and security settings (SSL/TLS). That information should be available in a user guide to your mail client. You can also contact your mail administrator in order to obtain those data.
Click on the Connection test to test if the connection was established successfully. If everything's correct, a green message 'SMTP test successful' appears. Now your email messages will be routed via your mail server and delivered from your email address
If an error message appears during a test or when sending an email, forward it to your system admin or consult a user guide to your mail client. The error message is a reply from your mail server informing you about the nature of the problem.
Note: It may be necessary to contact your system/mail provider to enable access for Billdu's mail server. We are using Amazon AWS located in Ireland.
