Email on your domain that lands in the inbox

Here's what it looks like in the panel

All your company email, in the same panel

Set up with best practices to stay out of spam.

• Guided DNS: When you register the domain it hands you the 4 records to add and verifies each one separately while you set them up.
• Mailboxes: Create, edit display name, password and quota, view and delete. The password is not stored in ArduMaker's database.
• Aliases: Domain aliases (info@ → juan@), personal aliases and temporary aliases that expire on their own.
• Bot accounts: API-driven mailboxes for your integrations, with a token you can regenerate whenever you want.
• Webmail and folders: Inbox, your own folders with an unread count, reading in plain text and HTML, and sending with attachments.
• Stats and access logs: Mailboxes, quota used, messages, last activity and SMTP/IMAP access logs per account.

Your email up and running

1. Register your domain: It gives you the 4 DNS records.
2. Add the DNS records: The panel verifies MX, SPF, DKIM and DMARC in real time.
3. Create mailboxes and aliases: For your team and for your apps.

How it works under the hood, and what to watch for

• There are four DNS records and each one does something different: MX says which server receives your email, SPF declares who can send on your behalf, DKIM signs it so the receiver can check it wasn't modified, and DMARC tells the receiver what to do if SPF or DKIM fail.
• The panel verifies all four separately and in real time while you add them. Without the three authentication records, your legitimate email ends up in spam: it is the most common reason a new domain doesn't reach its destination.
• The domain only becomes active once the DNS records are verified.
• Sending is capped at 5 emails per minute per account. Anything past that rate with no attachments is queued and goes out on its own.
• Attachments up to 25 MB per email.
• Each mailbox password is sent to the mail server and is not stored in ArduMaker's database.
• Bot accounts are API-driven mailboxes, with a token you can regenerate whenever you want. That is what you use so an app can send or read email without putting a person's password in it.
• Temporary aliases expire on their own, so there is nothing to remember to clean up.
• Deleting a domain removes all of its accounts and can't be undone.
• Real root over SSH: the panel is a shortcut, not a cage. Anything it does with a button, you can also do by hand.
