Unibox is your centralized inbox for managing all lead replies from one place, no need to log into multiple email accounts.
It consolidates all replies from your connected email accounts into one master inbox.
Primary: Replies from your leads in campaigns or lists
Others: Replies from non-leads. You can disable the 'Save non-Instantly emails in Unibox' to not sync non-leads replies.
Instead of logging into your email provider for each account, or setting up email forwarding rules, you can access all the emails in Unibox.

Best Practices for Replying to Leads
As soon as you get a reply to an initial cold email, you need to come up with a response to keep the conversation’s momentum going or schedule a call.
Here is what you should do when you get a positive response to your cold email:
Understand your prospect’s intentions
reply as quickly as possible
Have a call within 24-48h, helps with show up rates
Make it all about them
Don’t overwhelm them with too much information
Answer all their questions
Responding to Interested Leads
We created a guide that helps you turn interested leads into clients. Read about it here.
Respond to Every Opportunity
Before you respond to leads, you want to qualify them. If they aren’t interested, you can put the lead into the "Not Interested" folder or remove them.
Don’t leave interested people hanging in the dark; respond to every single person who contacts your business. Building relationships is key to the success of any business. Regardless of whether or not these conversations will result in conversions, you should invest time in talking with those who show an interest in your business.
Even if the lead doesn’t look as interested as you’d like when you first read the email, it can actually turn into a client. So give every opportunity a chance.
