What exactly does SMTPFox do?
SMTPFox is the dedicated SMTP infrastructure built specifically for high-volume cold email and outbound campaigns. We give you clean dedicated IPs, one-click full authentication (SPF, DKIM, DMARC, custom tracking domains), unlimited warmups, FoxBox unified reply inbox, real-time reputation monitoring, and seamless integration with tools like Instantly, Smartlead, Lemlist, and more — so your emails land in inboxes consistently, even at 500k–1M+ sends per month.
How long does setup take?
Under 5 minutes. Connect your domain → we auto-configure everything (DNS records, dedicated IP, warmup, tracking domains). No manual DNS fiddling. You’re sending with perfect authentication almost instantly.
Do I need technical knowledge to use SMTPFox ?
Nope — zero. Our one-click setup handles all the heavy lifting. If you can add a TXT record (or we do it for you via API), you’re good. Most users go from signup to sending in under 10 minutes.
Will my emails really hit the inbox (not spam)?
Yes — 98–99% inbox placement is our standard for properly warmed domains. We use clean dedicated IPs per domain/campaign, automatic warmups, spam trap monitoring, and rotating relays.
Which tools does SMTPFox integrate with?
We work seamlessly with all major cold email platforms: Emailbison • Instantly • Smartlead • Lemlist • Woodpecker • Apollo • Outreach • Clay • Saleshandy • Reply.io • and more via SMTP credentials or API.
