cirrux

Can I send from my domain in Cirrux while my mail still arrives at my current provider?

Yes. Add the domain in Cirrux and set the ownership, DKIM, SPF and DMARC records, but leave the MX records alone. You can then send from Cirrux, while incoming mail keeps going to your current provider until you switch the MX.

Which server receives your mail is decided by your domain's MX records. Everything else Cirrux asks for is about proving the domain is yours and that Cirrux may send for it. So you can start sending from Cirrux before you move your mail, whether you're with Google, Microsoft, or the mail service of your web host.

The records

Add the domain under Domains in admin.cirrux.co and set these at your DNS provider, as described in Domains & DNS:

  1. Ownership (TXT): proves the domain is yours.
  2. DKIM (CNAME): lets Cirrux sign the mail it sends.
  3. SPF (TXT): add include:_spf.cirrux.co to the SPF record you already have, next to your current provider. A domain can only have one SPF record, so don't create a second one.
  4. DMARC (TXT): keep the one you have, or add the one Cirrux suggests if you don't have one yet.

Leave the MX records as they are. Cirrux then reports that MX doesn't point to Cirrux, which is expected while you run both side by side.

You can send as soon as ownership and DKIM check out.

Receiving

Mail keeps arriving at your current provider. To also read it in Cirrux, forward it from there, or import it over IMAP. When you're ready to move completely, switch the MX records to Cirrux and all mail for the domain arrives in Cirrux. Every address then needs a mailbox or an alias in your workspace.

Google Workspace and Microsoft 365 can also deliver to both at once: see the split delivery guides for Google and Microsoft 365.
