How emailing works and how to set up/change the outgoing email address on your iPhone, iPad or Android

Updated yesterday

Billdu sends documents from its mailing server - they come from our email address invoices@mail.billdu.com. Replies an email is routed to your email address.

We also display your business name in front:

If your customer doesn't want to open a link, by clicking on "Click here to download PDF" a PDF file is downloaded directly.

The email message comes with a blue View invoice button. When clicked, a window with your invoice opens. Your customer can download a PDF file, pay the invoice, (if you use online payments), create a delivery note, accept an estimate/quote or print it out.

How to use your own email

You can send documents from your own email address and as PDF files.

Navigate to ⚙️Settings - Client communication and turn on "Send with iOS mail" or "Send with mail app"

By doing this you may not get push notifications about opening an invoice.

iOS

Billdu uses your native iOS mail app to send emails.

Android

Billdu checks, if you use a Gmail app. Otherwise it opens a dialog with multiple emailing choices.

When you use your own email app, invoices and other documents are sent as PDF files by your email app. You can see all outgoing emails in your Sent folder.

How to change the outgoing email address

iOS

You can select from which address your emails are sent. Set a primary email address in your mobile device settings under Settings – Mail – Default account

Android

Billdu uses Gmail as the mail app of choice.

If you'd like to keep the Gmail app on your phone and still send invoices from another email, it's necessary to add an email address to Gmail.
