What is Inbox Rotation?

Inbox rotation is a tactical approach employed by cold emailers, involving the distribution of email campaigns across multiple inboxes and domains rather than relying on a single sending email address. 

Not many out there let you send from multiple domains. SmartReach.io lets you do it.

Simply put is a technique where you send emails from multiple email addresses instead of just one. This way you do not have to create multiple campaigns for every email inbox.

This method ensures that the email-sending volume is spread across multiple email addresses or domains, reducing the risk of one inbox being adversely affected by deliverability issues.

Inbox rotation also helps you avoid hitting sending limits imposed by email providers. For example, the recent email sender policies released by Google & Yahoo.

It also improves the chances of your emails landing in inboxes instead of spam folders and manages different sender identities for various outreach campaigns or team members.

How does Inbox Rotation work?

By incorporating multiple cold email inboxes into your cold email software, such as SmartReach.io or any other tool providing inbox rotation, the system automatically rotates the sending inbox during campaigns. 

SmartReach.io has a human-like rotation to reduce the predictability of the inbox rotation.

For instance, if you have 1,000 emails to send and 10 inboxes, each inbox can be set to send 100 emails, preventing any single inbox from exceeding its sending limits. The sending will also rotate in patterns which cannot be detected easily

You could also add multiple domains like [email protected], [email protected], [email protected], etc to a single campaign.
