MailPilot is an email warmup and deliverability platform. It automates the process of building sender reputation for new or damaged domains by sending warmup emails through a network of real peer mailboxes - generating the engagement signals (opens, replies, archives) that inbox providers use to determine inbox trustworthiness. It also monitors live inbox placement, checks DNS authentication records, and alerts you when your deliverability drops.

How do I increase email deliverability?

To increase email deliverability: (1) Set up SPF, DKIM, and DMARC authentication records on your sending domain. (2) Run a 14–30 day email warmup program before sending at volume. (3) Keep bounce rate below 2% and spam complaint rate below 0.1%. (4) Send during business hours at consistent volumes - no sudden spikes. (5) Use plain-text email with personalized content for cold outreach. MailPilot automates steps 1–4 and monitors your placement in real time.

What is email warmup and why does it matter?

Email warmup is the process of gradually increasing your sending volume from a new or inactive mailbox to build sender reputation with inbox providers like Gmail and Outlook. ISPs track every sending domain - a brand-new address that immediately sends hundreds of emails looks identical to a spam operation. Warmup works by sending small numbers of real emails that get opened, replied to, and archived, signaling to ISPs that your domain is a legitimate sender. Without warmup, cold email campaigns from new domains typically land in spam.

Stop landing in spam. Start closing deals.

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%

ISPs decide in milliseconds. Without a warm sending history, new domains look identical to spam operations.

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.

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 up to 2 mailboxes, warm them up, monitor placement, run spam checks. No credit card, no trial clock. When you're ready to scale beyond 2 mailboxes, paid plans start at $19/mo flat - not per mailbox, not per seat. No math, no surprises.
