A sender account is a mailbox — Google Workspace, Microsoft 365/Outlook, or any custom SMTP/IMAP address — connected to AskOptimus so it can send and receive sequence emails on your behalf.
Mailbox rotation spreads outgoing emails evenly across every connected sender account instead of one inbox. This keeps volume per mailbox low, which protects sender reputation and improves inbox placement.
Yes. AskOptimus connects to Google Workspace and Microsoft 365/Outlook with native OAuth, plus any provider over standard SMTP/IMAP — no app passwords required.
Every connected mailbox is checked for SPF, DKIM, and DMARC alignment, ramped with daily sending caps during warm‑up, and automatically paused if bounce or spam‑complaint rates spike.
Free accounts include 1 mailbox. Paid plans support 3, 10, or 20+ mailboxes depending on tier, with no cap on how many domains you can rotate across.
