Email setup guides
Which DNS records each mail provider needs, in which order to add them, and how to check the result with live lookups.
Provider names identify the service a guide is written for. Apart from Zarfio, which is our own e-mail service, they do not imply partnership or endorsement. Values that a provider generates per domain are never printed here: copy those from the provider’s panel.
Google Workspace
Gmail on your own domain needs one MX record, one SPF record, a DKIM key that you generate in the Admin console, and a DMARC record.
Open the guideMicrosoft 365
Exchange Online gives every domain its own MX hostname and its own DKIM targets, so most values are copied from the admin center rather than from a guide.

Our email service
Zarfio is our own email service. The panel prepares the MX, SPF, DKIM and DMARC records for your domain; this guide covers the order of the steps and how to check each one.
Open the guideZoho Mail
Zoho Mail uses three MX records. The hostnames depend on the data centre your account lives in, so compare the table with what your admin console shows.
Open the guideProton Mail
Proton’s domain wizard walks through five records. MX and SPF are the same for every customer; the verification value and the three DKIM targets are generated for your domain.
Open the guideYandex 360
Yandex 360 for Business needs one MX record, an SPF record and a DKIM key that the organisation’s admin panel generates for your domain.

Enter your domain and choose a check. Each one is a live lookup from our server; a lookup that fails is reported as "could not be checked", not as a missing record.
