Why Sending From One Inbox Kills Campaigns
Gmail and Outlook cap daily sends per account. Hitting that limit — or sending high volume from one address — tanks deliverability and risks suspension.
- Gmail caps individual accounts at ~500 emails/day before throttling kicks in
- Sending high volume from one inbox damages its sender reputation quickly
- One inbox suspension can shut down your entire outreach campaign
- Managing multiple inboxes manually means juggling multiple tools and logins
- Most cold email tools charge per inbox — scaling outreach doubles your bill
How Inbox Rotation Works in mailtani
Add your inboxes, set weights, and mailtani handles distribution automatically.
Add your sending inboxes
Connect multiple inboxes via SMTP — different accounts, domains, or providers. Each inbox can be warmed up independently before being added to the rotation pool.
Configure rotation settings
Set daily send limits per inbox and rotation weights. mailtani distributes sends across inboxes automatically, staying under each account's safe threshold.
Monitor inbox health
Track delivery rate, spam rate, and open rate per inbox from the dashboard. Pause underperforming inboxes without stopping the whole campaign.
Scale Cold Email Without Burning Inboxes
Inbox rotation is included in every mailtani plan — no per-inbox fee.
Automatic distribution
mailtani rotates sends across your inboxes without manual intervention. Sends go out through whichever inbox has remaining daily capacity.
Per-inbox reputation protection
Each inbox sends a safe daily volume — never hitting throttle thresholds. Multiple inboxes mean one bad reputation event doesn't kill your whole campaign.
Per-inbox analytics
See open rate, spam rate, and deliverability metrics broken down by inbox. Identify which inboxes are performing well and which need more warmup.
Warmup + rotation together
Warm up a new inbox in mailtani and add it to your rotation pool once it's ready. Warmup and rotation share the same dashboard — no switching tools.
Scale without extra cost
mailtani doesn't charge per inbox. Add 5 or 50 inboxes to your rotation pool — the price stays the same.
Works across all providers
