# EmailQo — Cold Email Software with Warmup and Inbox Delivery

> EmailQo is cold email software built on your own Amazon SES account, Gmail, Outlook or any SMTP provider. It includes inbox warmup, AI deliverability checks, multi-step cold email sequences, reply detection and flat-price billing with no per-email charges.

## What EmailQo does

Q: What is the cheapest cold email software with unlimited sends?

Full comparison at emailqo.com/lemlist-alternatives.

Q: What is the difference between shared and dedicated email infrastructure?
A: Shared infrastructure routes your cold email through pools other senders use, creating neighbor reputation risk. Dedicated infrastructure routes through accounts you own so your reputation reflects only your behavior. See emailqo.com/dedicated-vs-shared-email-infrastructure.
