EmailQo
EmailQo is a cold email platform built around inbox placement. Instead of routing your campaigns through shared sending pools, EmailQo connects to your own Gmail, Outlook, Zoho, or Amazon SES account. Your sending reputation belongs entirely to you.
Every plan includes automatic email warmup and pre-send inbox health checks before every campaign goes out. Those checks cover SPF, DKIM, and DMARC validation, blacklist monitoring, spam trigger scanning, and enterprise spam filter simulation. Problems get caught before the send, not after open rates drop.
AI reply classification sorts incoming responses into interested, not interested, and out of office. Follow-up sequences pause automatically when a reply is detected so no prospect receives a follow-up after they have already responded.
Built for founders, sales teams, and agencies who are serious about inbox placement and want full control over their sending infrastructure.
