Sendpit compared to MailHog
MailHog is a local email testing tool that runs on your machine. Sendpit is a hosted SMTP sandbox that captures emails across environments and makes them visible to your entire team. Teams choose Sendpit when they need persistence, shared access, and CI/staging safety.
MailHog works great locally.
What about staging?
MailHog is a fantastic tool for catching emails on your local machine. Zero setup, instant feedback. But when you need shared visibility across environments—CI, staging, teammates—local tools hit their limits.
Sendpit is a hosted SMTP sandbox. Your whole team sees the same inbox, emails persist between deploys, and CI pipelines can send without local configuration.
What MailHog does well
MailHog is one of the simplest ways to capture emails during local development. Download a single binary, run it, point your app's SMTP config at localhost:1025, and you're done. Emails show up in a clean web UI at localhost:8025.
For solo developers debugging email templates or testing transactional flows, MailHog is a sensible default. It's free, open source, and requires no account or internet connection. If you're working alone on your laptop, it does exactly what you need.
The tool has been around for years and has a loyal following. There's a reason developers recommend it.
When local tools stop scaling
"Where did my emails go?"
MailHog stores emails in memory. Restart the process and they're gone.
"Can you screenshot that email?"
Teammates can't see your local inbox. Debugging becomes a game of screenshots.
"It works on my machine"
CI runners and staging servers need their own SMTP config. Local tools don't transfer.
"The QA team needs to verify that email"
QA can't access a developer's local MailHog. Emails sent from staging vanish into the void.
The moment you have multiple people working on the same project—or multiple environments sending emails—local tools start requiring workarounds. Self-hosting MailHog on a shared server is possible, but then you're maintaining infrastructure.
A hosted SMTP sandbox gives you the same capture-and-inspect workflow, but with built-in persistence, team access, and zero infrastructure management.
Local vs. hosted
Designed for its specific use case.
Hosted SMTP sandbox for teams.
Both capture emails. The difference is where the inbox lives and who can see it.
Same workflow, shared visibility
The core loop is the same: configure SMTP, send emails, inspect what arrives. The difference is that Sendpit's inbox is hosted, so your staging server, CI runner, and teammates all see the same emails.
You can inspect HTML, view headers, check links, and download attachments. Emails persist based on your retention settings. No process restarts, no lost emails, no screenshots in Slack.
One SMTP config works across local dev, CI, and staging. Everyone on the team sees what's being sent.
Emails are stored temporarily, encrypted, and automatically deleted based on your retention settings.
Choosing the right tool
MailHog makes sense if...
-
You're working alone on your local machine.
-
You don't need emails to persist between sessions.
-
You prefer offline-first, open source tools.
-
Your workflow doesn't involve CI or shared staging.
Sendpit makes sense if...
-
You need teammates or QA to see the same emails.
-
Your CI pipeline or staging server sends emails.
-
You want emails to persist and be retrievable.
-
You don't want to self-host infrastructure.
Many teams use both. MailHog for quick local debugging, Sendpit for shared environments. They solve different problems.
