Frequently Asked Questions
Is SmartReach really 100% free forever?
Yes, absolutely! The entire software is 100% free and source-available. Our business model is selling managed mailboxes and deliverability infrastructure, so this software tool is completely free for you to use forever with zero artificial limits.
Can I connect Google Workspace and Microsoft 365 inboxes?
Yes! You can connect standard SMTP and IMAP credentials from Google Workspace, Microsoft 365, Zoho Mail, Fastmail, or any custom mail server. SmartReach smoothly rotates sending across all of them.
How does the reply detection work?
SmartReach checks your incoming mailboxes automatically. As soon as a prospect replies, their campaign status is updated to 'Replied', future follow-ups are frozen immediately, and the full thread appears in your UniBox for you to respond.
Is there a limit on how many leads or mailboxes I can add?
No! There are no artificial paywalls, mailbox limits, or lead caps. You can import extensive CSV lists with your prospect contacts, map custom attributes, and connect as many mailboxes as your campaign requires.
How does SmartReach protect email deliverability?
By distributing outreach across multiple sender accounts, randomizing intervals between sends, respecting human working hours, and maintaining clean deliverability standards so your emails land right in the primary inbox.
