What is Sendpit?
Your emails work.
You just can't prove it.
Sendpit captures and inspects emails before they ever reach real users—so failures are caught early, not reported later.
Start Free — No credit cardThe email that never arrived
Your app sent a password reset. SMTP returned 250 OK. Logs look clean.
Three days later, a support ticket: "I never got the email."
This happens constantly. Emails fail after they leave your server—silently, invisibly, without a trace. Spam filters. Typos. Provider throttling. Blacklists you didn't know you were on.
And the worst part? You only find out when users complain. Or churn. Or tweet about it.
A safe place to break your emails
Point your staging SMTP at Sendpit. Every email your app sends gets captured—not delivered.
Then inspect it. Check the HTML. Verify the headers. See if the "unsubscribe" link actually works. Test attachments. Preview mobile rendering.
All without a single email reaching a real inbox.
See how it worksThree steps. That's it.
Create a mailbox
Get SMTP credentials in ten seconds. One per environment, one per team—whatever you need.
Point your app at it
Swap your SMTP host. Standard port, TLS supported. Works with any language, any framework.
See every email
Open Sendpit. Every email your app sent is there. HTML rendered. Headers exposed. Attachments downloadable.
No code changes. No SDKs. No vendor lock-in.
Email failures cost more than you think
Onboarding drops
If your welcome email doesn't arrive, your user doesn't activate. That's not a bug. That's lost revenue.
Support load spikes
"I never got the reset link" is your most common ticket. Every one of those took five minutes. Multiply that by your user base.
Trust erodes quietly
Users don't always complain. They just stop opening. Or switch to a competitor. You never see the churn coming.
Most teams don't lose users because of bugs.
They lose them because something quietly didn't work.
Built for teams that ship
Developers
Stop using your personal inbox for testing. Stop accidentally emailing production users from staging.
QA teams
Verify email flows without backend access. Screenshot the rendered email. Flag issues before they ship.
Product teams
Review transactional copy in context. Catch broken links, bad formatting, missing tokens—before launch.
Founders / Solo builders
You don't have a QA team. Sendpit is your QA team for email.
Not for everyone: Sendpit is for testing and development. If you're looking for a transactional email provider, marketing automation, or inbox deliverability tools—we're not that. And we don't pretend to be.
Let's be clear
Not an ESP. We don't send emails. We catch them.
Not a log viewer. We render and inspect—not just dump raw text.
Not error tracking. We don't monitor your app. We monitor your emails.
Not deliverability testing. We don't predict inbox placement—we help you make sure the email itself is correct.
You already test your code.
Why not your emails?
Every other system in your stack has visibility. Logs. Metrics. Alerts. Tests. Dashboards.
Email? You hit send and hope.
Sendpit fixes that. One SMTP change. Full visibility.
No credit card. Free tier available. Setup in under two minutes.
