Assign Multiple Inboxes
Learn how to assign multiple inboxes in a Smartreach.io campaign to scale your cold email outreach with inbox rotation. Step-by-step guide included.
How To Assign Multiple Inboxes In A Campaign?
While creating any campaign during the channel setup step we need to add/assign multiple inboxes to a specific campaign.
Step-1: During the campaign creation process, navigate to Channel Setup. Under the email section, start by selecting the primary sending email account as mentioned below:
Step-2: Click on the + Add More icon.
Step-3: Next, click on Add emails.
Step-4: Select another email account that will be used as another sending email account/inbox and also initiate further changes under “Max emails per day from each sender email” which is 50 now and we can make it up to 500. For instance, if you set the max emails per day to 100 and you have 10 emails, you would be sending a total of 1000 emails per day.
Once it’s done click on Save Changes.

Your campaign will now use multiple inboxes, and the emails will be sent randomly. It's important to note that we can't specify which prospects will receive emails from specific sending accounts; the distribution will be entirely random.
For example If we have 100 prospects, 5 rotating email IDs, and a maximum of 20 emails per day from each sender email, SmartReach will select them randomly. Each email ID will then reach out to 20 prospects in a random manner.To get more clarity about inbox rotation Click here.
Frequently asked questions
- What is Inbox rotation?
Inbox rotation, or email rotation, means sending emails from different email addresses instead of just one. This helps you avoid reaching email sending limits, increases the likelihood of your emails ending up in inboxes rather than spam folders, and lets you handle various sender identities for different outreach campaigns or team members.
- Does Inbox rotation improve email deliverability?
Certainly!When we send emails from different addresses instead of just one, it helps us avoid getting flagged as spam.This is because sending too many messages from a single address can be seen as suspicious, doing this helps us to maintain the sender positive reputation and makes it more likely that your emails will end up in the main inbox.

You're allowed to include several email domains when sending from a single campaign.
