## Receiving

Mail sent to your domain or to your users' own inboxes, handed to your code as it arrives.

-   [Inbound email APIReceive email in your app over an API. Point an MX record at AI Inbx or connect Gmail and Outlook, and every message arrives as a signed, parsed JSON webhook.ThreadingAttachmentsMailboxesWildcard domains](/solutions/inbound-email-api)
-   [Email reply parserParse every email reply down to what the sender wrote: quoted text and repeated signatures removed, answers typed inside the quote kept where they were.ThreadingMailboxes](/solutions/email-reply-parser)
-   [Auto-reply detectionTell an out-of-office, a ticket acknowledgement or a bounce from a real reply. Every inbound email arrives with a category, decided from headers and content.MailboxesSuppressions](/solutions/auto-reply-detection)

## Sending

Mail leaving your product, paced and checked before it goes, from your domain or theirs.

-   [Send email APISend email from your domain or your users' own Gmail and Outlook with one API call. Opt-outs and pacing are checked first, and replies land on the thread.ThreadingMailboxesPacingSuppressions](/solutions/send-email-api)
-   [Scheduled email APISchedule an email up to 30 days ahead, then move or cancel it by id until its time comes. It is composed then, so suppressions and threads stay current.ThreadingSending hoursSuppressions](/solutions/scheduled-email-api)
-   [Email open trackingTrack email opens and clicks per domain or per send. Apple privacy prefetches and security scanner clicks arrive flagged as bots, each with its reason.Threading](/solutions/email-open-tracking)
-   [SPF DKIM DMARC checkCheck a customer's SPF, DKIM and DMARC records over an API. Live lookups at their own nameservers name the record that is wrong and the change that fixes it.Wildcard domains](/solutions/spf-dkim-dmarc-check)
