Common questions
How many inboxes do I need?
Start conservative. Use the calculator to map daily send goals into inbox count, domain count, and provider mix.
Should I use Google Workspace or Microsoft 365?
Google is stronger for Gmail-heavy audiences. Microsoft 365 can lower cost and diversify infrastructure. Serious operators often use both.
What matters more than price?
DNS accuracy, send limits, replacement policy, support speed, and domain isolation matter more than saving a few cents per inbox.
