Email hosting and SMTP relay
Business mailboxes on your own domain with webmail, IMAP and JMAP, and an authenticated SMTP relay with delivery events for your applications.
Frequently asked questions
Do I need to move my DNS to use email hosting?
No. If we host your DNS zone, we publish the MX, SPF, DKIM and DMARC records for you. If not, you add the records we show, and we check them every few minutes.
Which mail clients work?
Any IMAP client on port 993 and SMTP submission on 587 or 465, plus webmail. Autoconfig and autodiscover fill in the settings for Thunderbird, Outlook and phones.
How does the SMTP relay protect deliverability?
We DKIM-sign every message and only send from domains you have verified. We warm up new IPs gradually, and bounces feed a suppression list. Mail leaves from a load-balanced cluster instead of a single server.
