Does LeadFuze integrate with IMAP?
LeadFuze integrates with Gmail or Office 365 accounts only.
We focus on Gmail and Office 365 because each server is configured differently and has unique limitations we can't possibly support.
With that said, our recommended best practice for cold emailing is to register a .net or .co version of your main domain.
After that, set up a Google Apps account to send from that .net or .co version and you can have your emails forward to your main account.
