Stop paying per inbox.
Bring Your Own AWS.

The bridge that connects AWS SES directly to Instantly & Smartlead. Get enterprise-grade deliverability and Unlimited Inboxes for a flat fee.

Compatible with Instantly.ai, Smartlead.ai, and all IMAP clients.

Why Agencies Switch to SESBox

We solve the "Missing Link" that keeps you locked into expensive providers.

Save 80% on Infra

AWS charges ~$0.10 for 1,000 emails. We charge a flat fee. No more paying $3 for every single inbox you create.

Ban-Proof Setup

Stop buying sketchy "Microsoft Accounts" that get banned in 90 days. AWS is enterprise infrastructure. You own the account.

Connects to Instantly

We provide the "Warm-up Capability" that AWS is missing. Connect to Instantly or Smartlead in seconds using standard credentials.

Why Agencies Switch to SESBox

Don't risk your business on cheap, grey-market accounts.

Feature SESBox (AWS) Cheap Resellers (MS)
Sending Capacity 6,000+ / day 500 / day (Limited)
Ban Risk Zero (You Own It) High (Shared Tenants)
Deliverability 98% (Sustainable) 99% (Until Banned)

Simple, Flat Pricing

Pay for the infrastructure, not the inbox count.
