Use GlowBox with your stack
Use GlowBox under any SMTP-capable tool.
The GlowBox “use-with” model is one SMTP pattern everywhere: GlowBox is the deliverability layer underneath your CRM or sequencer—your team keeps the same screens.
Keep your workflows, sequences, and automations. Swap the SMTP layer to GlowBox so email routes through the healthiest mailbox automatically—no UI change for your team.
HubSpot is live. More tools are queued—ask and we’ll prioritize.
- • Copy GlowBox SMTP host, username (pool name), and password.
- • Paste into your tool’s SMTP settings.
- • GlowBox routes via the healthiest mailbox at send-time.
- • Warmup, reputation, throttling, and monitoring happen automatically.

Frequently asked questions
What does “use with GlowBox” mean?
It means GlowBox sits under your existing tool via SMTP: you keep the same UI and swap mail settings so sends route through GlowBox pools.
Is HubSpot the only live integration?
HubSpot is highlighted today; HighLevel and other SMTP-capable tools follow the same credential pattern—ask us to prioritize yours.
Do I need engineering resources?
Usually no. If your tool supports custom SMTP, operations or revops can paste host, username, and password and validate with a test send.
Will GlowBox change my sequences or automation logic?
No. GlowBox only changes how mail is transported after your tool hands off the message.
