Inbox Rotation – Smart Sending Across Multiple Inboxes

Inbox Rotation is a feature that allows you to send your email campaigns from multiple email addresses (inboxes) instead of relying on just one. It’s a proven strategy to boost email deliverability, prevent domain blacklisting, and maintain high inbox placement rates — especially when you’re sending cold emails or high volumes.

Why Inbox Rotation Matters

Improved Deliverability

Emails sent across multiple inboxes are less likely to be flagged as spam.

Reduced Spam Triggers

Prevents high volume from a single sender, lowering suspicion.

Avoid Blacklisting

Rotating senders helps distribute the load and protect domain/IP reputation.

Higher Sending Limits

Send more emails daily without exceeding limits of a single inbox.

Inbox Diversity

Emails appear more natural to recipients and inbox providers.
