Keeping another email provider
You don't have to switch everything at once. Faivelo can sit beside your current provider while you move, and some teams keep both for good.
Switching without a gap
Mailboxes can only be created once Faivelo's MX record is published for the domain (plus the DKIM records for sending). Faivelo's MX doesn't have to be the only one yet:
- Add the domain and publish Faivelo's records. You can add Faivelo's MX next to your old provider's with a larger priority number (lower priority), so mail keeps going to the old provider.
- Once the domain is ready for mailboxes, create them and import your old mail.
- Remove the old provider's MX. New mail now arrives at Faivelo.
While another provider's MX has the same or a higher priority than Faivelo's, the domain page shows that mail is still routed there, and the domain isn't fully verified. Mailboxes work, but campaigns, the transactional API and choosing the domain as a sending domain wait until Faivelo's MX is the one that wins.
Running both on one domain
Some providers (Google Workspace, Microsoft 365, Zoho) can route mail for some addresses on to another server, often called split delivery. On Faivelo's side: publish Faivelo's records with Faivelo's MX at a lower priority than the other provider's (as in step 1 above) and leave it there, create the Faivelo mailboxes, then point the other provider's routing for those addresses at mx.faivelo.com. Setting up the routing happens at the other provider, so follow their guide. The domain stays not fully verified in this setup, with the limits described above.
One limitation to know first: a Faivelo mailbox can't send to mailboxes on the same domain that live at the other provider. Faivelo treats the whole domain as its own and delivers mail for it internally, so a message from jane@yourcompany.com (on Faivelo) to sam@yourcompany.com (at Google) never reaches Google. Mail to and from everyone else works normally.
Using a subdomain instead
The cleanest way to run both is to give Faivelo its own subdomain, such as team.yourcompany.com, so addresses look like jane@team.yourcompany.com. Add it like any domain on the Domains page and publish its records under the subdomain. Your main domain's MX stays with your current provider, nothing about its mail changes, and the two never get in each other's way.
