Not just sending —
a complete mail server.
While you send email through the API, your team mail, calendar and contacts live on the same infrastructure. Thanks to open standards, whichever email app you prefer connects directly. And if you ever want to move to another platform tomorrow, your data comes with you.

Mail server features
All the power of a modern mail server + a Turkish-language interface.
Full-featured webmail
A personal email client opens right in the browser. Composing, foldering, labeling, search and attachment management are gathered in a single interface. An automatic setup profile is provided for mobile devices.
Shared inbox & calendar & contacts
Addresses like info@ and support@ are visible to the team with assignment support (Starter and up). Manage the company calendar and contacts in one place.
Resource booking
A booking calendar for resources such as meeting rooms, projectors and vehicles (Business and up).
Multi-layer spam + virus protection
Bayesian, rule-based and DNSBL filtering layers work together. Every incoming attachment passes through an antivirus scan. Greylisting and reputation scoring also run in the background.
Snooze + undo send
Snooze a message to a future time. Undo a send within a 30-second window after sending.
Mail-2FA + audit log
Step-up verification is applied to important emails. Every mailbox operation is written to an immutable audit record.
Migrating from a traditional workspace solution: CalDAV/CardDAV moves your existing calendar and contacts in a single pass. Your email history is pulled over via IMAP. An automatic setup profile is provided for mobile devices. The migration typically takes 1–3 business days and runs without interruption.
