ApolloOne provider is one point of failure
When every mailbox you own sits with one provider, one bad week reaches every campaign at once.
One change hits every campaign
A provider tightens its limits or flags a batch of accounts, and every mailbox you own feels it the same day.
Microsoft is its own project
Its setup, users and records all work differently from Google, so the second provider never quite gets set up.
A second screen to check
Each provider reports problems its own way, so a suspended Microsoft mailbox hides from the screen you watch.
Two providers, one way of working
You buy Microsoft mailboxes in the same order as Google ones, and Arcinbox sets up, connects and watches them the same way.
Set up for you, like Google
Arcinbox gets the Microsoft 365 side ready, publishes the records, creates the users, and sets their names, usernames and photos.
- SPF, DKIM, DMARC and MX on every domain
- Names, usernames and profile photos set for you
- Bought in the same order as Google
SPF, DKIM, DMARC and MX published.
