GlowBox lets agencies manage
outbound infrastructure cleanly,
predictably, and at scale.
GlowBox provides your agency with visibility,
deliverability and control.





For large companies GlowBox provides the capacity to send up to 1,000 emails per pool daily, and with several pools you can send thousands of emails per day.
We recommend our Annual Plan for agencies
Best balance of price, capacity, and scalability.
$600/year1 pool · 10 mailboxes · 500 emails/day total
Need more capacity? Add a second pool for $400 (instead of $600).
Save $120/year vs. Starter — more mailboxes, cheaper long-term scaling.
One payment, no monthly lock-in.

Onboarding Playbook
Spin up a new client in hours, not weeks:
- Create a pool per client to isolate routing, limits and reporting.
- Connect SMTP
- Start routing and monitoring immediately: add mailboxes as volume grows.
Capacity Math (Made Simple)
Pools define:
- How many emails can be sent safely
- When to scale infrastructure
- How many mailboxes are needed
- No guesswork. No surprises.
