Recommended workflow in Outlio
Create or collect the accounts you plan to connect.
Confirm every domain has DNS authentication.
Connect accounts in Outlio one at a time and verify status.
Set conservative daily limits per sender.
Assign accounts to campaigns through inbox rotation.
Quality checks
- Group accounts by domain or audience.
- Keep a spreadsheet of provider, domain, owner, and daily limit.
- Do not mix accounts with very different sender identities in the same campaign.
Common mistakes to avoid
- Assuming one domain passing DNS means all domains are ready.
- Using inactive accounts in rotation.
Done well, this should leave you with
A cleaner Outlio setup, fewer avoidable campaign issues, and a more reliable path from setup to replies.
