# Invoices by mail

> Your own inbound mail address, and who is allowed to send to it.

Every administration has its own Glimps mail address. Anything sent to it is treated as an invoice.

Find the address under **Settings > Email**. Copy it, and give it to suppliers, or forward to it from your own mailbox.

## Who may send

Glimps does not accept invoices from just anybody, because your mail address is easy to guess once one supplier has it.

Three things decide it:

<AccordionGroup>
  <Accordion title="Your own team is always allowed" icon="users">
    Every user and administrator of the administration can mail invoices in. You do not need to add them.
  </Accordion>

  <Accordion title="Allowed senders" icon="user-check">
    Add a supplier, your bookkeeper, or anyone else who should be able to send.

    Add one address, such as `billing@vandijkverpakkingen.nl`. Or add a whole domain by starting with an at sign, such as `@vandijkverpakkingen.nl`. A domain entry covers subdomains too.
  </Accordion>

  <Accordion title="Accept every sender" icon="door-open">
    A switch that takes anything that arrives. Handy when invoices come from many one-off addresses.

    It also means a stranger who knows the address can push a document into your administration. The duplicate check and bank account check still run, but the invoice does land in your list.
  </Accordion>
</AccordionGroup>

<Warning>
  Adding one address of a supplier only allows that address. Add the domain if the supplier mails from several addresses.
</Warning>

## What Glimps does with the mail

1. The attachments are taken out. Only PDF attachments are read.
2. Each invoice becomes its own item in the list.

If a mail holds several invoices in one file, Glimps says so and asks whether to split it. See [How Glimps reads an invoice](/intake/reading-invoices#several-invoices-in-one-file).

## When a mail does not arrive

<AccordionGroup>
  <Accordion title="Nothing shows up in the list">
    Check the sender against your allowed senders. A refused mail does not create an invoice.
  </Accordion>

  <Accordion title="The attachment is not a PDF">
    Glimps only reads a PDF from a mail. A photo, a Word file, or a UBL file on its own does not create an invoice. Ask the sender for a PDF, or download the file and [upload it](/intake/upload) yourself.
  </Accordion>

  <Accordion title="The invoice arrived twice">
    That is the duplicate check doing its job. Open the newest one, decide which to keep, and delete the other. See [Checks](/invoices/checks#duplicates).
  </Accordion>
</AccordionGroup>
