Does it work with my email provider?

The answer is almost certainly YES! Connect in seconds with OAuth or SMTP/IMAP.

The problem

Most emails fail before the recipient ever sees them.

1 in 5
emails never reaches the inbox
Even well-crafted campaigns from legitimate senders hit spam - not because of content, but because of sender reputation.
45%
of cold emails are marked spam before they're read
ISPs decide in milliseconds. Without a warm sending history, new domains look identical to spam operations.
7 days
to permanently damage a sending domain
Send too much, too fast from a cold domain. Your reputation drops, your domain gets flagged, and recovery takes weeks.

Who uses MailPilot

If you send emails, you need warmup.

Here's how different teams use MailPilot to land in the inbox.

PAIN POINT: Missing quota because prospects never saw your email.

Every cold email deserves a fighting chance.

Your reps craft perfect pitches that land in spam before anyone reads them. MailPilot builds sender reputation so every outreach reaches the primary inbox - not the spam folder.

  • More replies from cold outreach
  • Shorter sales cycles
  • Higher quota attainment
  • Outreach Readiness indicator

What makers said at launch

View on Product Hunt →

“Tried it on a small domain that was getting flagged and the DMARC monitoring caught a misaligned record I'd missed for months. The seed inbox placement report across Gmail and Outlook was honestly more detailed than what I've seen from pricier tools.”

Fikret Samacı
Product Hunt review

“Spun up MailPilot on a small subdomain and was surprised how quickly it flagged a DKIM misconfiguration I'd missed for weeks. The inbox placement reports across Gmail and Outlook are genuinely useful for catching warmup issues before they tank deliverability.”

Nazar Akkan
Product Hunt review

“The staged domain reputation repair approach is smart — it's the kind of detail most warmup tools skip and end up making things worse. Really thoughtful execution.”

Real results. Real inboxes.

What real people say about email warmup - and the placement numbers they got after doing it right.

“In the last 24 months, I've warmed up 250,000+ cold email inboxes. I've NEVER seen someone struggle from low deliverability when they follow a proper inbox warm-up protocol.”

“Most deliverability issues come down to poor sender reputation, high bounce rates, and spam triggers. Fix those fundamentals, and your emails will land where they should.”

honest take: most warmup tools show you a "score" that means nothing. mailpilot shows you actual inbox vs spam breakdown per ESP. that's the only thing that matters for cold email

Got questions? Fair.

What teams ask before connecting their first mailbox.

Most warm-up tools score themselves. MailPilot measures real placement in real inboxes - and tells you when your reputation is good enough to actually send. The warm-up is the part you don't see; the placement data is the part you trust.

Yes. OAuth integration for Google Workspace and Microsoft 365. Direct SMTP for everything else (SendGrid, Postmark, Amazon SES, your own server). One mailbox or ten thousand - same setup flow.

A fresh domain takes 14–21 days to reach 90%+ placement. An aged domain that's clean: 5–7 days. A damaged domain in remediation: 30–45 days. The dashboard tells you, hourly, where you stand and what comes next.

They are read, replied to, archived, and starred by real human-shaped behavior on real inboxes. Filter providers see normal conversation patterns. You see a reputation graph going up.

MailPilot runs continuous seed-list monitoring during your real sends. If a campaign hits Promotions on Gmail or Junk on Outlook, you get an alert with the specific signal that triggered it (content, authentication, IP, or sending velocity).

Yes - free means free. Connect 1 mailbox free, warm it up, monitor placement, run spam checks. No credit card, no trial clock. When you're ready to scale beyond the free plan, paid plans start at $9/mo flat (10 mailboxes on Starter) - not per mailbox, not per seat. No math, no surprises.
