Zapmail Infrastructure Audit — Is your cold email landing in spam?

Scanning…

Audit for yourdomain.com

Reading your public DNS records…

Your domains are hosted on Cloudflare.

A recent large-scale blacklisting event took out roughly 25% of Cloudflare-hosted sending domains, including an entire competing infrastructure provider. If you send cold email from here, you are one list update away from silent deliverability collapse.

Stop guessing. Send from infrastructure that actually lands.

Pre-warmed, US-hosted Google & Microsoft mailboxes on isolated domains. Automated SPF, DKIM and DMARC. Zero suspensions in 2.5 years. Start sending from day one.

Why teams switch to Zapmail

The infrastructure layer of the cold email stack, built for people who send at scale and cannot afford to land in spam.

Pre-warmed inboxes

Skip the 3 to 4 week warm-up. Start sending on day one from real Google and Microsoft accounts, not shared SMTP relays.

Workspace isolation

One domain per workspace. One client's burned domain can never drag down another. Built for running many senders at once.

Automated DNS

SPF, DKIM, DMARC and custom tracking domains configured instantly and correctly. What used to take 45 minutes per mailbox takes minutes.

Zero suspensions

In 2.5 years, not a single Zapmail mailbox has been suspended. US and EU IPs on clean, isolated domains that stay in the inbox.
