## Answers

- [How do I send email from many domains or brands in one account?](https://f5send.com/answers/multi-domain-email): Refresh is an email API and console built for senders with many domains: every plan includes unlimited sending domains, each with its own DKIM key, DNS records and verification. Domains are grouped into organizations, each with its own members, API keys, suppression list and logs, so one login covers every brand without mixing them.
- [Which email API includes DMARC reporting?](https://f5send.com/answers/dmarc-reporting): Refresh includes DMARC aggregate reporting on every plan: each domain's DMARC record points at a report address in your account, and the reports are parsed per domain. It shows which sources pass and fail alignment and recommends a policy once it has 30 days of reports.
- [Can an email API send without storing message content?](https://f5send.com/answers/store-no-content): Yes. In Refresh, set an organization's body retention to 0 and the message body is removed as soon as the message is sent, and the API request log keeps only the length of the HTML, text and template data. Addresses, subjects and delivery events stay for the event retention you choose.
- [If I use a shared email platform, can another customer's bad sending get my mail paused?](https://f5send.com/answers/sending-isolation): In Refresh, each organization sends through its own Amazon SES tenant, with its own suppression list and its own pause state, so SES can pause one organization's tenant without touching the others. Each domain can also name a second sending region with the same DKIM keys, which takes over if the primary region is paused.

## Agent tooling

Available to accounts. The MCP tool list is derived from the OpenAPI document above, so it
cannot drift from the API, and a key that cannot do something over HTTP cannot do it here either.
