Frequently asked questions

What is a GlowBox “integration”?

It is standard SMTP: you add GlowBox’s host, pool username, and password in your tool’s email or SMTP settings. No marketplace app or API connector is required.

Which tools work with GlowBox?

Any outbound or CRM tool that lets you send email through custom SMTP—including HubSpot, HighLevel, Instantly, Apollo, Smartlead, and many others listed on this page.

Does GlowBox replace my CRM or sequencer?

No. GlowBox sits under your existing stack and routes mail through healthy mailboxes; your UI, sequences, and workflows stay the same.

How long does setup usually take?

Most teams paste SMTP credentials and send a test message in under ten minutes. Larger rollouts add time for pools and mailboxes, not for rebuilding workflows.
