EmailQo

Cold email only works if it reaches the inbox. Most outreach tools assume you’ll buy new domains, new inboxes, and a separate warmup service just to get started. EmailQo takes a different approach: it works with the email accounts you already have.

EmailQo warms up your sending reputation gradually, with real back and forth activity between accounts, instead of a sudden burst of outbound email that gets you flagged. Alongside warmup, it checks your SPF, DKIM, and DMARC records and flags misconfigurations before they cost you replies. If your domain shows up on a blacklist or your authentication setup has a gap, you find out from EmailQo instead of from your bounce rate.

Once your sending reputation is solid, EmailQo helps you run the actual campaigns: sequences, personalization, and reply tracking, all from the inboxes you already send from. There’s no need to provision dedicated sending infrastructure or hand your outreach to a black box warmup network you can’t inspect.

For agencies, EmailQo supports multiple client workspaces under a single login. Each client gets their own sending domains, sender accounts, and deliverability data, so you can manage outreach for several clients without juggling separate logins or exporting data between tools.

EmailQo also ships a set of free deliverability tools: an SPF checker, a DKIM checker, a DMARC checker, an email grader, and a warmup schedule calculator, so you can check your setup even before you sign up.

Who it’s for: founders running their first outreach campaign without a dedicated sales team, agencies managing email deliverability across multiple client accounts, and sales or marketing teams scaling cold email who want to keep using the accounts they already trust instead of standing up new sending infrastructure.

The goal is simple: fewer emails in spam, using the tools and accounts you already have.
