// the challenge

What goes wrong without proper warmup

Welcome emails miss the inbox

New product domains have no sending history. Gmail and Outlook filter onboarding emails to spam - silently killing activation before users even get started.

Activation links never seen

If your email verification or password reset lands in spam, users churn before they ever experience your product. No warmup = invisible transactional email.

No visibility before launch

Most SaaS teams discover deliverability issues after launch when activation rates drop. MailPilot gives you placement data before your first real user signs up.

Silent SPF/DKIM errors

Sending via Postmark, SendGrid, or Resend with misconfigured authentication? Your emails look legitimate to your team but land in spam for recipients.

// how mailpilot helps

Everything you need to land in the inbox

Pre-launch domain warmup

Connect your transactional sending domain before your product launches. Build ISP reputation so your first onboarding email lands in the primary inbox - not spam.

Onboarding placement monitoring

Track inbox placement for welcome emails, activation links, and trial expiry reminders across Gmail and Outlook - not just delivery rate, but where they actually land.

Auth error detection

MailPilot continuously validates SPF, DKIM, and DMARC on every sending domain. You'll get an alert before auth drift causes deliverability failures at scale.

Reputation repair for established products

If your sending domain has accumulated spam complaints over time, MailPilot's structured re-engagement warmup rebuilds trust with ISPs through positive signal injection.

ESP & API integration

Works alongside Postmark, SendGrid, Resend, AWS SES, and Mailgun. Use the API to pull deliverability scores into your internal dashboards or alerting systems.

Subdomain warmup

Running separate subdomains for transactional, marketing, and product email? Manage warmup for each in parallel with isolated reputation scores per sending identity.

Up and running in 3 steps

Add your sending domain

Connect the domain your product sends from - whether it's your main domain or a subdomain like mail.yourapp.com. MailPilot audits your DNS and ESP auth config immediately.

AI warmup runs in the background

MailPilot exchanges warmup emails with real peer mailboxes automatically. No manual effort. Your deliverability score updates daily so you always know where you stand.

Ship knowing your emails will land

Launch your product or new email flows with confidence. Your onboarding emails hit the primary inbox instead of sending users on a "check your spam folder" scavenger hunt.
