Frequently asked questions
What is GlowBox for SMB and sales teams?
GlowBox is the SMTP deliverability layer under your CRM: it warms mailboxes, routes sends through healthy inboxes, and monitors placement while your reps keep the same sequences.
Do we have to migrate tools or rewrite sequences?
No. If your CRM or sequencer supports custom SMTP, you paste GlowBox credentials and keep your workflows.
How does GlowBox improve replies?
By improving inbox placement—when fewer emails hit spam, more prospects see your message and can reply.
Is GlowBox only for cold email?
Cold outbound is the primary use case, but any SMTP-sent outbound—from nurture to follow-up—benefits from healthier routing.
