Custom receiving domains

Every inbox gets a Notix address that works straight away. You can also receive at any address on your own domain, such as orders@inbound.acme.com. Received mail lands in your shared inbox, in the API and in the email.received webhook.

Choose a domain to receive on

You can receive on a domain you have verified for sending, or on a subdomain of it.

Use a subdomain such as inbound.acme.com if anyone already gets email at the main domain, for example through Google Workspace or Microsoft 365. Receiving works through an MX record, and a domain has one set of MX records. Pointing the main domain's MX record at Notix would move all of your company's mail to Notix, and your team would stop getting it. Notix warns you and asks you to confirm before it lets you do that.

You cannot receive on mail.acme.com. That name already carries bounces for your sending domain.

Turn on receiving

1. 1

   Open the domain

   Go to Domains and open a verified domain. Only team admins can turn receiving on.

2. 2

   Pick the name and turn it on

   In the Receiving card, keep the suggested subdomain or type your own, then press Turn on receiving.

   Add the records

   Add the records the card shows at your DNS provider. Each one has a copy button. The values below are examples; copy the real ones from the card.

   Type	Host	Value	Priority	TTL
   MX	inbound.acme.com	inbound-smtp.eu-west-1.amazonaws.com	10	3600
   TXT	notixin._domainkey.inbound.acme.com	p=... (shown in the console)		3600

   The TXT record proves to Amazon SES, which receives the mail for Notix, that you own the name. When you receive on a domain that is already verified for sending in the same region, there is no TXT record to add.

   The MX record must be the only one for the name, or the one with the lowest priority number. Mail goes to the preferred server first.

4. 4

   Check the records

   Press Check records. Each record shows Found, Missing, Wrong value or Not checked. Receiving starts once the MX record points to Notix, the TXT record is found, and Notix has switched the name on. Until then the card says Waiting for records. DNS changes can take up to an hour, so press Check records again if it is still waiting.

Where the mail goes

Mail to any address on an active receiving domain is accepted:

• An address that belongs to an inbox goes to that inbox.
• Every other address goes to your team's first inbox. If you have no inbox yet, Notix creates one called Inbox.

Mail for a name whose receiving is off is not accepted, and nothing is bounced back to the sender.

Turn off receiving

Press Turn off in the Receiving card and confirm. Notix stops accepting mail for the name at once. Remove the MX record afterwards. Deleting the sending domain also turns off receiving on it.

Read the mail

Mail received on your own domain is read the same way as any received mail: in the shared inbox, with List received messages, or through the email.received webhook. Files that come with it are covered in Attachments.

A key restricted to one domain reads only mail delivered to that domain or its subdomains.
