How to connect multiple accounts from the same provider
Go to Integrations in mailfloss and click Add integration. Follow the connect steps for your provider to add the second account as a new integration. When the provider asks you to log in or for an API key, use the second account.

When the second account is connected, go back to Integrations. mailfloss groups the accounts under the provider's name, with one row per account. To add another account later, click the + Connect another link under the group (for example, + Connect another Ortto account).

Click an account's row to open it. Each account keeps its own settings and its own waiting list, so you set up each one separately.
To rename an account, open it and click the pencil icon next to its name at the top of the page. Pick a name that tells you which account it is.
And, you're done!
