Emails

MicroApps runs real email hosting on your own domain: proper mailboxes, the DNS records that keep your mail out of spam, and metrics so you can see what is flowing.

Availability

Email hosting is offered on request - contact us and we'll enable it for your account. Until then the account's mailbox limit sits at zero and creating one is refused.

Before you can create a mailbox

The domain has to be yours, proven. Publish the microapps-verify TXT record and let the domain verify first; until then, creating a mailbox on it returns Domain ownership is not verified. See Domains.

Mailboxes

A mailbox is a full email address like [email protected] with its own password and quota. Each mailbox has:

• Storage - a quota from 1 to 50 GB, changeable later.
• Forwarding (alias) - send a copy of every incoming message to another address. It cannot be the mailbox's own address.
• Catch-all - a mailbox flagged catch-all receives everything sent to addresses on the domain that do not exist. One mailbox per domain can hold the flag; turning it on elsewhere is refused until you turn it off on the first. A real mailbox always wins over the catch-all, so mail to an address that does exist goes where you expect.
• Status - ACTIVE or DISABLED, so you can pause a mailbox without deleting it. (A SUSPENDED state also exists, but that one is set by us, not you, and a suspended mailbox cannot be edited.)

A new mailbox is live within a few seconds of creation. It is worth waiting those few seconds before testing the login rather than concluding something is broken.

DNS records

Setting up email on a domain generates the records that make mail deliverable. Publish them at your DNS provider and we verify them for you:

Record	Does
MX	Routes incoming mail to our servers.
SPF	Says our servers are allowed to send for your domain.
DKIM	Signs your outgoing mail so receivers can trust it.
DMARC	Sets your policy and collects reports.
SRV	Two of them, so mail clients can auto-discover the IMAP and submission ports.

Deliverability (SPF, DKIM, DMARC alignment) is handled for you - that's the difference between mail that lands and mail that vanishes.

Connecting a client

Any standard mail app works. The username is always the full email address.

Protocol	Port	Security
IMAP (receiving)	993	SSL/TLS
SMTP (sending)	587	STARTTLS

One-click unsubscribe

Every message we send on your behalf includes a one-click unsubscribe link. When a recipient uses it, that address is added to your domain's suppression list and you stop mailing it - which keeps you on the right side of inbox providers. You can review the list and remove an address (to resume sending) whenever you like.

Metrics

Sent, received, and bounced counts, rolled up at the mailbox, domain, and account level, with daily breakdowns.
